Assignment; Right of First Refusal

20.1

Notwithstanding the foregoing, Airspan may assign or otherwise transfer this Agreement or its rights under it, or delegate its obligations, to any of its affiliates.

Page 18

(i)

Airspan shall provide to Axtel the soliciting or offering material used in connection with any contemplated sale of the FWA Business (the “FWA Information”) at the same time any such FWA Information is provided to any third party potential purchaser (the “Potential Purchasers”), subject to execution by the Parties of a non-disclosure agreement in a form and substance reasonably satisfactory to Airspan, but no less restrictive on Axtel than the non-disclosure agreement executed with the Potential Purchasers; and provided, however, that Airspan may not offer, solicit interest in or sell the FWA Business to any company which is a direct competitor of Axtel or does not have the necessary resources (human and/or technical), at Airspan’ reasonable judgment, to manufacture the Products and/or to provide the technical support required by Axtel, including without limitation, Teléfonos de México, S.A. de C.V. or any of its affiliates (the “Restricted Companies”);

(ii)

Airspan hereby grants to Axtel a right of first refusal (“RFR”) with respect to any offer received by Airspan from any third party which Airspan proposes to accept (including any revised offers), allowing Axtel to purchase the FWA Business on terms not less favorable than such offer, subject to Axtel having made, within forty five (45) days after Airspan shall have delivered written notice to Axtel of such offer or revised offer (the “Vendor’s Notice”), a single deposit for the amount equal to five (5) percent of the amount of the third party offer (the “Deposit”) into an interest bearing escrow account. Once Airspan has received the Deposit, Axtel shall have the right to perform a due diligence investigation of the FWA Business, and Airspan shall be obligated to promptly provide all the information and access that Axtel reasonably requires for the evaluation of the FWA Business; and

(iii)

in the event of any such sale to a purchaser other than Axtel, such new vendor shall assume all of Airspan’s obligations under this Agreement.

20.2

If Axtel exercises its RFR, Airspan and Axtel shall have ninety (90) days from payment of the Deposit to negotiate in good faith and enter into a purchase agreement pursuant to which Airspan will sell the FWA Business to Axtel, unless a longer period of time is stated in the offer received from the Potential Purchaser, in which case such longer period shall prevail (the “Offer Period”). If the Parties have entered into such an agreement by the end of the Offer Period, the Deposit shall be credited towards the purchase price of the FWA Business. If the Parties have not entered into such an agreement by the end of the Offer Period, Axtel shall forfeit in favor of Airspan the Deposit, and Airspan shall have the right to sell the FWA Business to any Potential Purchaser other than a Restricted Company, subject to the terms and conditions of Section 20.3 below; provided, however, that if the terms of the proposed sale are more favorable to such Potential Purchaser than the best offer (from Airspan’ perspective) presented by Axtel to Airspan during the Offer Period, then the RFR shall again apply to such sale, but Axtel shall not be obligated to provide any additional Deposit.

20.3

If Axtel shall decline in any instance to exercise its RFR or the Parties fail to enter into the purchase agreement as described in Section 20.2, Airspan shall have the right for a period of one year from the date of such declination or failure, to sell the FWA Business to a Potential Purchaser (except if such Potential Purchaser is a Restricted Company) without prior notice to Axtel, on terms which are not more beneficial to such Potential Purchaser than those set forth in Vendor’s Notice. If the foregoing conditions are not met, the RFR shall again apply to such sale; provided, however, that the 90-day term provided in Section 20.2 above shall be reduced to forty five (45) days and Axtel shall not be obligated to provide any additional Deposit.

Scope

1.1

This section defines the essential performance characteristics of the Airspan Internet Fixed Wireless Access system (Internet FWA). The scope of the section is confined to the airside equipment that supports wireless transmission in the local loop, i.e. that part of the system from the Base-station network interface to the subscriber premises terminal interface (telephone socket), together with associated network management operations systems in the element management layer. The specifications for the switch, service gateway and other associated backhaul equipment are therefore specifically excluded from this section.

2.1

General description

2.1.1

Intentionally Left in Blank

2.1.1.1

Purpose of Internet FWA

The Internet FWA system allows telecommunications operators to construct high quality telephone access networks between customers’ premises and local exchanges. The system uses cellular point to multi-point wireless technology as a replacement for traditional copper-based local loops. A major advantage of FWA technology is that it allows operators to create new access networks quickly and with minimum capital investment.

Each terminal in the Internet FWA system is capable of delivering PSTN circuit-switched services through two standard analogue telephone lines. In addition to the PSTN services, a packet-mode service may be used to deliver ‘always-on’ connections between one or more Internet Service Providers (ISPs) and the computer equipment of subscribers.

The Internet FWA system provides a frequency division duplex radio link to a subscriber transceiver system and operates in the 3.4 to 3.6 GHz band. The air interface utilizes time division multiplex on the downlink and time division multiple access on the uplink. The system comprises a network of Radio Base-stations (RBS) arranged on a cellular plan and these are connected to the PSTN or to the public Internet by a conventional back-haul network. Each base-station consists of one or more Integrated Transceiver Systems (ITSs).

2.1.2

Sub-systems

The Internet FWA system contains two Network elements (NEs):

·	Remote Service System (RSS)

·	Radio Base Station (RBS)

The Internet FWA system contains three Operations systems (OSs):

·	Radio Element Manager (REM)

·	RSS Installation System (RIS)

·	Field Engineering Terminal (FET)

Page 2

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

The Remote Service System (RSS)

This system provides the subscriber with two independent analogue exchange lines and optionally a packet data service interface. The system consists of the RSS Terminal Unit (RTU), an RSS Power and Connection unit (RPCU) and an RSS Data Adapter (RDA) or Dongle Data Adaptor

The RTU is mounted externally to the subscriber premises and contains a directional antenna, radio electronics and the two analogue line interfaces to carry PSTN services. The unit is powered from the RPCU indoor unit that plugs into the subscribers mains supply. A ‘drop cable’ connects the RTU to the RPCU. The RPCU contains two sets of telephone sockets for connection to the subscriber’s telephone equipment. In order to provide the optional packet data service, an RDA is supplied along with a special version of the RTU that contains the required data interface. The packet data service makes use of the HPNA standard to multiplex the data onto ‘line 0’ of the telephone wires. The RDA connects to the subscriber’s personal computer.

The Integrated Transceiver System (ITS)

One or more ITSs form the basis of the radio base-station and have been designed to serve an area of up to 5km radius in a typical urban environment and up to 20km in a rural environment.

Voice band circuits from the ITS are connected to the switch by means of E1 links running a V5.2 protocol. The packet data service is also routed over E1 links to the service gateway using L2TP (layer 2 tunnel protocol). The ITS can route any slot from the ‘circuit’ E1s to any slot on the airside interface.

In principle, an ITS can be provisioned as a 3, 6, 9, 12, 15 or 18 bearer configuration. RBS configurations specifically supported by installation and maintenance processes provide tri-sectored configurations with 18 or 27¹ ^{In
the Axtel application, the 27 bearer base-stations generally provide only 26
bearers due to limited availability of RF channels.} RF carriers, or a tri/hex-sectored RBS with 48 RF carriers. The 27-carrier configurations require the use of two ITSs, and the 48-carrier configuration requires the use of three ITSs. The 48 bearer base-station is designed to provide coverage in two ‘RF layers’, the first layer allowing a frequency re-use of one to be employed whilst a more conservative frequency plan is used in the other layer. Service to the individual RSS can be switched between these two layers depending on the interference environment experienced at that RSS.

Radio Element Manager (REM)

The Radio Element Manger (REM) is a high performance, high capacity management system and is used to perform the Operation, Administration, Maintenance and Provisioning (OAM&P) procedures for the Internet FWA network. One REM can manage up to 200 ITSs and 150,000lines. The REM is primarily composed of a server platform, a client platform, additional user PCs and a Network Communications Server. Their respective purposes are described below. The REM supports a total of 4 expert and 4 standard user sessions.

¹ In the Axtel application, the 27 bearer base-stations generally provide only 26 bearers due to limited availability of RF channels

Page 3

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

The REM server performs all provisioning related, object-related, event and alarm related processing, together with some of the GUI processing. Further, the server stores all object, event and alarm related data and state. As such, the majority of REM software executes on the server. The server also interfaces directly to a customer’s High Level Management System (HLMS) for subscriber provisioning.

The REM Client primarily acts as the host platform for the additional user GUI screens. It provides some of the GUI processing, and acts as a platform on which additional user scripts run.

PCs running Exceed software connect with the REM client to allow access for additional users.

The Network Communication Server (NCS) is an integrated terminal server and modem unit, which provides a connectivity solution from the REM to its network of ITSs. It also provides connectivity to the Remote Maintenance Terminal that is used during the subscriber hardware installation.

Field engineering terminal (FET)

The installing engineer will use this equipment during installation and commissioning of Base-station equipment. The FET application runs on a PC platform using a LINUX operating system. The FET is intended to connect locally into an ITS and allows control of the ITS as well as access to status information. Each FET requires a license key to enable operation and these are available from Airspan.

RSS Installation system (RIS)

The installing engineer will use this equipment to control the RSS during installation, to aid antenna alignment to the Base Station, to measure the performance of the RF link and to enable the connection. The primary component of the RIS is the Remote Maintenance Terminal (RMT).

2.1.3

External interfaces

The physical layer external interfaces of the Internet FWA system are:

·	Analogue line interface at the RSS

·	Packet data interface at the RSS

·	A.C. power interface at the RSS

·	PCM (E1) interface at the RBS

·	Packet data (E1) interface at the RBS

·	D.C. power interface at the RBS

·	External alarm interface at the RBS

·	Analogue line interface at the RIS. This is used to connect the RMT to the REM to download provisioning data.

·	Analogue line interface at the REM

·	Ethernet interface at the REM. This is used to connect the REM to higher-layer operations systems.

General description of the air interface

2.3.1.1

Physical layer

The physical layer of the Internet FWA air interface uses digital time division multiplex/time division multiple access (TDM/TDMA) with a 10-slot frame structure. Uplink and downlink carriers are paired, and separated by a fixed duplex spacing of 99.84MHz. A TDM/TDMA channel (i.e. one time-slot one on one RF carrier) is known as a physical channel. In the maximum configuration, one ITS provides 18 pairs of RF carriers, and 180 physical channels.

The uplink carriers are contained within the frequency band 3425 MHz to 3450 MHz, and the downlink carriers are contained within the frequency band 3525 MHz to 3550 MHz.

The modulation scheme for both the uplink and downlink direction is pi/4 shifted differential quadrature phase shift keying (p/4DQPSK) with a nominal symbol rate of [*] symbols/s. The gross data rate is [*] kbits/s per carrier.

Reserved channels are used to allow contention access by terminals. These access channels are not available for carrying subscribers’ voice or data traffic.

2.3.1.2

Channel plan

The Internet FWA system operates over 78 RF channels, with a nominal channel spacing of 307.2 kHz. The lowest uplink channel (Ch. 2) has a nominal centre frequency of 3425.8944 MHz. The highest downlink channel (Ch. 79) has a nominal centre frequency of 3549.3888 MHz. The fixed duplex spacing is equivalent to 325 times the channel spacing.

2.3.1.3

MAC layer for PSTN traffic

One physical channel is capable of carrying a single 32 kbit/s ADPCM circuit-switched connection, or one half of a 64 kbit/s PCM circuit-switched connection.

Page 6

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

2.3.1.4

MAC layer for the Packet data service

Physical channels can be allocated in groups of six to carry packet-mode traffic. One group of six physical channels is described as a packet channel.

2.3.2

RF performance of the ITS equipment

2.3.2.1

Maximum transmit power

The maximum transmit power from the ITS is not less than 28 dBm for each carrier, measured at the antenna port of the TMU.

2.3.2.2

Transmitter implementation loss

The transmitted signal from the ITS is a close approximation to an ideal p/4DQPSK signal. The additional carrier to noise margin required to demodulate the practical transmitted signal, compared to an ideal signal is less than 1 dB.

2.3.2.3

Spectrum due to modulation

The spectrum due to modulation at the output of the ITS is as follows:

Channel	Mean power (dBc)
N	0 dBc (by definition)
N ± 1	£ -24.5 dBc
N ± 2	£ -40 dBc
N ± 3	£ -50 dBc
Any other channel	£ -60 dBc or -60 dBm (whichever is greater)

The mean power is measured using an ideal receiver with root-raised-cosine filtering with transition factor (a) = 0.4, and with the receiver tuned to the centre of the appropriate adjacent channel.

2.3.2.4

Minimum receiver sensitivity

The receiver sensitivity for the ITS is not greater than -101.5 dBm, measured at the antenna port of the TMU, for a bit error ratio (BER) of 10^-3 before forward error correction. This measurement assumes an ideal transmitter.

2.3.2.5

Receiver selectivity

The ITS receiver selectivity is specified in terms of the level of interfering signal consistent with a bit error ratio (BER) for the wanted signal of less than 10^-3 before FEC. The interfering signal is assumed to be from a signal source with the ideal characteristics of the Internet FWA radio system, centered on the applicable adjacent channel. The wanted signal is assumed to be from a similar ideal source and set at a level 3 dB greater than the level required for BER = 10^-3 in the absence of interference. The carrier to interference levels are as follows:

Page 7

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

Channel	Carrier/Interference ratio for BER = 10^-3

N ± 2	£ -58.5 dB
Any other channel	£ -84.5 dBc

2.3.3

RF performance of the RSS equipment

2.3.3.1

Maximum transmit power

The maximum transmit power from the RSS is not less than 44.5 dBm EIRP in RF channels 8 to 73 inclusive, and not less than 41.5 dBm EIRP in the remaining channels. This transmit power specification applies to the complete RTU including the antenna.

2.3.3.2

Transmitter implementation loss

The transmitted signal from the RSS is a close approximation to an ideal p/4DQPSK signal. The additional carrier to noise margin required to demodulate the practical transmitted signal, compared to an ideal signal is less than 1 dB.

2.3.3.3

Spectrum due to modulation

The spectrum due to modulation at the output of the RSS is as follows:

Channel	Mean power (dBc)
N	[*]
N ± 1	[*]
N ± 2	[*]
N ± 3	[*]
Any other channel	[*]

The mean power is measured using an ideal receiver with root-raised-cosine filtering with transition factor (a) = 0.4, and with the receiver tuned to the centre of the appropriate adjacent channel. The measured power is averaged over duration of the time-slot containing the uplink transmission.

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

2.3.3.4

Minimum receiver sensitivity

The receiver sensitivity for the RSS is not greater than [*] dBm in RF channels 8 to 73 inclusive, and not greater than [*] dBm in the remaining channels. The received signal is measured at the connector of the RTU antenna, for a bit error ratio (BER) of 10^-3 before forward error correction. This measurement assumes an ideal transmitter.

2.3.3.5

Receiver selectivity

The RSS receiver selectivity is specified in terms of the level of interfering signal consistent with a bit error ratio (BER) for the wanted signal of less than 10^-3 before FEC. The interfering signal is assumed to be from a signal source with the ideal characteristics of the Internet FWA radio system, centered on the applicable adjacent channel. The wanted signal is assumed to be from a similar ideal source and set at a level 3 dB greater than the level required for BER = 10^-3 in the absence of interference. The carrier to interference levels are as follows:

Channel	Carrier/Interference ratio for BER = 10^-3
N	[*]
N ± 1	[*]
N ± 2	[*]
N ± 3	[*]
N ± 4	[*]
N ± 5	[*]
Any other channel	Blocking specification applies

2.3.3.6 RSS receiver dynamic range

The dynamic range of the RSS receiver is from the limit of sensitivity to -20 dBm, measured at the antenna connector of the RTU. Over this dynamic range the BER of the received signal (measured before forward error correction) is not greater than 10^-3.

2.3.3.7 RSS antenna gain

The gain of the RSS antenna is between [*] dBi and [*] dBi at the peak of the response. The nominal beamwidth is 14 degrees (i.e. ± 7 degrees). The rejection of cross-polar signals in the main antenna response is not less than 20 dB compared to a co-polar signal of identical level. The maximum level of side-lobe responses is [*] dBi, and this limit applies at azimuth angles from 22 degrees to 338 degrees with respect to the peak response.

2.3.4

Automatic power control

To minimise interference in the network, the system incorporates automatic uplink RF power control whereby the ITS attempts to maintain a constant received signal strength (RSSI) of -80dBm for each active call or packet connection. If the RSSI strays from this target, the ITS will send a message to the appropriate RSS requesting an appropriate modification to the uplink RF power. The ITS normally integrates the RSSI over a 30s period before deciding whether an adjustment is required although there is a faster attack period at the start of a call or packet connection. At the end of a call or connection, the RSS calculates a new RF power that will be used to initiate the next call or connection on the same RF channel.

Page 9

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

To maintain an appropriate initial uplink RF power level during extended periods of call inactivity, network test calls are automatically scheduled to each RSS on each of its operating channels. Just as is the case for normal calls, the uplink RF power is adjusted appropriately at the end of a network test call. The scheduling period is normally set to 23 hours.

2.3.5

Combining diversity

In ITS configurations with 2 or more TMUs per sector, the system is configured to execute two-path maximum ratio combining in the uplink. The implementation of this feature delivers the theoretical benefit of maximum ratio combining with less than 1 dB implementation loss.

The TMU receiver is wideband and covers all of the uplink spectrum. This means that the IF signals from 2 TMUs in the same sector differ only by virtue of being received from 2 physically separated antennas. The two I.F signals are fed to separate arms of each receiver pair of every TBM in the sector. The TBM hosts three such receiver pairs where each pair is configured to an appropriate channel. The maximum ratio combining algorithm is executed independently on each receiver pair.

2.3.6

Dynamic carrier list management

Dynamic carrier list management feature allows each RSS to modify the classification of individual RF carriers in response to periodic measurements of the received (downlink) signal. Each RSS notifies the ITS of changes in carrier classification, allowing the ITS to allocate channels with a priority reflecting the recent quality of downlink carriers. This feature has proven to be effective in combating the effects of static frequency-selective fading, and minimizing the impact of downlink radio interference from nearby RBSs in the same network. This feature is extremely valuable in networks where tri-sector and tri/hex-sector RBSs are built in adjacent or nearby cells.

2.4

Equipment configurations

2.4.1

RBS configurations

RBS configurations that can be constructed using SR14 consist of one, two or three ITSs. The table below lists the configurations that can be used.

Page 10

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

Base station configuration	ITS sector organisation	Circuit-switched E1s	Packet-switched E1s	Maximum number of E1 connections
18-carrier, tri-sector, Type I	6.6.6	6	0, 2	8
26-carrier, tri-sector, Type II	6.6.5	6	0, 2	11
26-carrier, tri-sector, Type II	3.3.3	3	0	11
26-carrier, tri-sector, Type III	9.8	6	0, 2	13
26-carrier, tri-sector, Type III	9	3	0, 2	13
26-carrier, tri-sector, Type IV	9.9	6	0, 2	13
26-carrier, tri-sector, Type IV	8	3	0, 2	13
27-carrier, tri-sector, Type I	6.6.6	6	0, 2	11
27-carrier, tri-sector, Type I	3.3.3	3	0	11
27-carrier, tri-sector, Type II	9.9	6	0, 2	13
27-carrier, tri-sector, Type II	9	3	0, 2	13
48-carrier, tri/hex-sector	6.6.4	5	0, 2	21
	6.6.4	5	0, 2
	6.6.4	5	0, 2

The column ‘ITS sector organization’ denotes the number of RF carriers than are enabled in each sector. No relationship is implied between the position of the elements of this list and the numbering of ITS sectors; thus a sector organization of 6.6.5 applies equally to configurations where the five-carrier sector is ITS sector 1, 2 or 3.

The tri/hex configuration is described as 6.6.4. The six-carrier sectors are associated with the hex-sectored antennas, and the four-carrier sector is associated with the tri-sectored antennas. By default, the tri-sector is ITS sector 1.

The following rules apply:

·	Where PDS is required at an ITS, two TPM-PDs must be fitted.

·	Each TPM requires one E1 connection between the ITS and the local exchange.

·	Each TPM-PD requires one E1 connection between the ITS and the service gateway.

Page 11

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

Some of the base station configurations make use of more than one ITS. PDS can be enabled or disabled on a ‘per-ITS’ basis, and so it is possible to create a multi-ITS configuration where only one or two of the ITSs has PDS enabled.

2.4.2

PSTN traffic capacity

The PSTN traffic capacity of the supported RBS configurations is detailed in the table below. Note these figures apply where PDS is not provided; the PSTN capacity of an ITS with PDS is necessarily lower.

Base station configuration	Reference capacity (E)
Base station configuration	Soft sector = 0%	Soft sector = 10%
18-carrier, tri-sector, Type I	[*]	[*]
26-carrier, tri-sector, Type III & IV	[*]	[*]
27-carrier, tri-sector, Type II	[*]	[*]
48-carrier, tri/hex-sector	[*]	[*]

The reference capacity is defined as the capacity at 1% probability of blocking for long ADPCM calls, with the optimum distribution of traffic loading between ITS sectors.

The soft-sector capacity assumes that 10% of the traffic loading arises from subscribers in the overlap regions between sectors, and that the soft-sectored load is distributed evenly between three overlap regions (3.3% of the total load in each overlap). In 26-carrier RBSs of type III and IV, and 27-carrier RBSs of type II, there is only one overlap region where a benefit is derived from soft sectoring; in these cases, the capacity gain is relatively small. In the tri/hex-sectored ITS, soft-sectoring is not enabled between hex-sectors.

One ITS with V5.2 interface can support a maximum of 2048 PSTN lines, and a maximum of 2048 RSSs.

2.4.3

Packet data traffic capacity

2.4.3.1

Number of packet channels at an ITS

Packet channels at an ITS can be configured subject to the following rules:

Page 12

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

·	Packet data can be supported by ITSs with sector arrangement 6.6.6, 6.6.5, 8, 9, 9.8, 9.9, 6.6.4 (tri/hex)

·	All packet channels consist of 6 physical channel pairs

·	An ITS that supports PDS has two TPM-PDs

·	One TPM-PD may support zero to four packet channels inclusive

·	One ITS supports a maximum of 36 physical channels (i.e. six packet channels)

·	The largest packet partition allowed in one sector is three packet channels

·	In bi-sector or tri-sector ITSs, if the ITS provides PDS then each sector must have at least one packet channel

·	In a tri-sector ITS, the sum of the number of packet channels in the smallest two packet partitions must not exceed four. This ensures that sectors will not be split across TPM-PDs.

2.4.3.2

Number of simultaneous PPP and MAC connections

The packet data service supports a maximum of:

·	700 packet data subscribers per ITS

·	[*] simultaneous PPP connections per ITS

·	[*] simultaneous active MAC connections per packet channel

·	[*] simultaneous active MAC connections per TPM-PD

·	[*] simultaneous active MAC connections per ITS

2.4.3.3

Traffic capacity of a packet channel

Each packet channel (consisting of six physical channels) provides a shared channel with an aggregate capacity for users’ packet data traffic of not less than [*] kbps in the downlink direction, and not less than 84 kbps in the uplink direction. PPP, TCP and IP headers applied at the users’ computers are assumed to form part of the useful throughput.

2.4.3.4

Peak throughput for a single PDS user

The peak throughput for a single user is approximately 96 kbps in the downlink direction (using the USB interface) and approximately 92 kbps in the downlink direction (using the RS-232 interface). The peak throughput for a single user is approximately 42 kbps in the uplink direction.

Note that these are peak figures, and apply when the user has exclusive use of three physical channels. In normal operation, the packet channel capacity is shared between a number of users, and mean throughput figures for individual users will be lower than these peak values. The operator must ensure that sufficient packet channels are configured to offer reasonable quality of service to packet data subscribers.

2.4.3.5

Reduction in PSTN capacity

The remaining PSTN traffic capacity at an RBS with packet data service is defined in the following table. These figures assume that 10% of the offered traffic is from soft-sectored terminals.

Page 13

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

Base station configuration	Reference capacity (E)
Base station configuration	One packet channel in each sector	Two packet channels in each sector
26-carrier, tri-sector, Type III & IV	194.0	178.0
48-carrier, tri/hex-sector	327.0	279.0

2.5

External interfaces

2.5.1

ITS to transmission system

The interface between the ITS and the transmission system is defined by ITU-T

G.703 11/2001, ‘Physical/electrical characteristics of hierarchical digital interfaces’. Only the interface at 2048 kbit/s is supported in Internet FWA.

As an additional requirement, Internet FWA requires that the long-term frequency accuracy of the E1 signal from the transmission system is better than 10^-7 (0.1 ppm). Transmission equipment does not normally re-time digital traffic, and so this frequency accuracy is usually dependent on correct configuration of the local exchange (for PSTN connections) or the packet data network.

Internet FWA complies with ITU-T G.823, ‘The control of jitter and wander within digital networks which are based on the 2048 kbit/s hierarchy’.

2.5.2

ITS to local exchange

The framing structure of the signal between the ITS and the local exchange is defined by ITU-T G.704 10/1998, ‘Synchronous frame structures used at 1544, 6312, 2048, 8448 and 44 736 kbit/s hierarchical levels’, and ITU-T G.706 04/1991, ‘Frame alignment and cyclic redundancy check (CRC) procedures relating to basic frame structures defined in Recommendation G.704’.

The voice coding for circuit-switched traffic complies with ITU-T G.711 11/1988, ‘Pulse code modulation (PCM) of voice frequencies’.

Signaling between the ITS and the local exchange uses the V5.2 protocol, defined in the ETSI V5.1 Specification ETS 300 324-1, V 1.2.2, ‘V-Interfaces at the digital local exchange (LE) - V5.1-Interface (based on 2048 kbit/s) for the support of access network (AN)’, and ETSI V5.2 Specification ETS 300 347-1, V 2.1.2, ‘V-interfaces at the digital local exchange (LE) - V5.2 interface (based on 2048 kbit/s) for the support of access network (AN)’. Only requirements for PSTN services apply to Internet FWA.

2.5.3

ITS to packet data network

Internet FWA requires that the E1 signal from the packet data network must comply with the framing structure defined in ITU-T G.704 (see above for a detailed reference). Time-slot zero contains a frame synchronization signal, and the remaining 31 time-slots are joined together to provide a connection with an aggregate capacity of 1984 kbit/s.

The layer-2 tunnel between the ITS and the packet data network uses a protocol stack consisting of the point-to-point protocol (PPP), Internet protocol (IP), user datagram protocol (UDP) and the layer-2 tunneling protocol (L2TP). These protocols are defined as follows:

Page 14

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

·	PPP: Internet engineering task force (IETF) STD 51, ‘The point to point protocol’

·	IP: IETF RFC 791, ‘Internet protocol’

·	UDP: IETF RFC 768, ‘User datagram protocol’

·	L2TP: IETF RFC 2661, ‘Layer two tunnelling protocol (L2TP)’

2.5.4

RDA to PC

The RDA provides a choice of two different serial data standards at the PC-RDA interface:

·	Asynchronous serial interface (commonly known as RS-232) as defined in ANSI/TIA/EIA-232-F-1997, Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, and

·	Universal Serial Bus (USB), using the ‘full-speed’ option, as defined in Universal Serial Bus specification, Rev. 1.1 and USB class definitions for communications devices, Rev. 1.0.

2.5.5

Shortly after the introduction of the New F6 RSS unit the RDA will be replaced with a dongle that will provide the same functionality as the existing RDA unit.

2.6.	Additional Specifications

2.6.1

In addition to the Product’s Specifications set forth in this Annex D, the Parties agree to include as part of this Annex D the Product’s Specifications that will be set forth in the Compact Discs to be named as: (i) Internet Fixed Wireless Access, MR 14.0.3 “Customer Documentation Suite” and (ii) Internet Fixed Wireless Access, Maintenance Release MR 14.0.3 System Line Up that will be delivered with MR14.03 in February 2003.

2.6.2

New RSS Unit

Summary of the RSS changes

The new Proximity RSS Unit shall have the same form, function and fit of both of the current RSS Equipment jointly (the F2 and F5 based RSS equipment), pursuant the specifications provided to Axtel by Airspan and Nortel Networks (as the former manufacturer). The New RSS Unit will be known as the F6.

The changes are summarised as follows:

·	Airspan shall supply a single variant of the RSS. In particular, all RTUs will contain a packet data interface suitable for interconnection with the existing RDA.

·	The 48 volt indoor power supply, known as the RPCU, shall be revised to remove unused functionality.

·	The RTU environmental specification shall be changed so that the low operating temperature limit will be -20 C rather than -40 C.

·	The New RSS will incorporate the original Drop Cable Connector (NTEG 99GR)

Page 15

Annex D -Product Specifications

Purchase and License Agreement for FWA Equipment-December 2004

Single variant RSS

In accordance with the Amendment Agreement No2, all New RSS Units will be supplied with a packet data interface, i.e. the RSS will be ‘packet data ready’. This will potentially enable Axtel to supply existing subscribers requesting the packet data service with an RDA or equivalent device without the need for replacing the RTU.

48 volt indoor power supply

It had been agreed that a revised solution for the indoor power supply will be supplied. A number of solutions are possible, but relative to the current RPCU, the following specification changes are included:

·	Eliminate the mains buzzer functionality, which is understood to be disabled by the Axtel installation teams.

·	Remove the 2 secondary RJ11 sockets: It is understood that a remote RJ11 Box is the preferred Axtel method of installation.

Restrict the mains input voltage to Mexican requirements: The current RPCU is designed for the global marketplace and operates with input voltages from 85volts to 270volts ac. The power supply will be redesigned specifically to suit Mexican requirements (88volts to 132 volts ac). Output power ratings will remain unchanged.

·	The RPCU plastics material will remain essentially unchanged, but will incorporate additional spacer/wider lugs and the blanking of the fins to reduce the likelihood of Water and Bug.

Should there be any changes in mechanical form of the power supply, these will be agreed with Axtel in due course.

Change to RTU lower operating temperature limit

The RTU environmental specification will be changed so that the low operating temperature limit will be -20 C rather than -40 C. This is believed to be acceptable for deployments in Mexico.

Single outer sheath drop cable

For the avoidance of doubt there will be no change to the existing specification, which already states the dual outer sheath drop cable.

F6 support in SR14.2

The F6 RTU will require a new software image and support for this will be provided in the SR14.2 system release.

Others

A separate label will be added to the RTU to distinguish between and F6 from other RTU’s

THE WARRANTIES EXPRESSLY SET FORTH IN THIS ANNEX “G” CONSTITUTE THE ONLY WARRANTIES MADE BY AIRSPAN WITH RESPECT TO THE PRODUCTS. SUCH WARRANTIES ARE IN LIEU OF ALL OTHER WARRANTIES AND CONDITIONS, WHETHER STATUTORY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

1.1	Airspan warrants that the Products will be free from defects in materials and workmanship and will function substantially in accordance with the applicable specifications during the warranty period of twelve (12) months from the respective Delivery Date (“Warranty Period”).

1.2

Airspan undertakes to promptly remedy pursuant the terms set forth in this Annex “G” all defects discovered in the Products within the Warranty Period and properly notified to Airspan in accordance with this Section. Repaired or replaced Products shall have a new warranty period of 180 days from the date of delivery to Axtel or up to the end of the original Warranty Period, whichever is longer.

1.3	Subject to the said Warranty Period(s), Airspan warrants that the Products, and any part thereof, will comply and function in accordance with the specifications set forth in Annex “D” of the Agreement and all of the requirements of the Agreement.

1.4

If an item of Product is or becomes defective during its Warranty Period, Airspan will at its option either repair or replace the item. In the event Airspan determines that repair or replacement as set forth in this Annex G cannot be made using commercially reasonable efforts (which determination shall be made within thirty (30) days after Airspan receives written notice from Axtel) Airspan will give Axtel a credit equal to the purchase price paid by Axtel for the Product, provided that Axtel has returned such Product to Airspan.

Assumptions for Repair Services

The following assumptions will govern the provision of repair Services for Products covered by the warranty in the Warranty Period:

Airspan will incur the expense of shipping the repaired unit or the replacement unit to Axtel using a method and carrier selected by Airspan. Airspan is responsible for loss of, or damage to, an FRU while it is in Airspan’ possession or in transit to Axtel, as well as to pay all applicable duties, taxes, and other charges associated with the importation of the repaired or replacement FRU into the country of destination.

Unless required for operational reasons and agreed upon with Airspan, the replacement FRU will be at the then-current hardware and firmware release levels as they are made Generally Available (GA) by Airspan. Upon a specific request of Axtel for repair of a quantity of RTUs with a specific software release version, the parties will work together to define a mutually agreeable process to satisfy such specific request, provided that such a process does not cause Airspan to incur any out of pocket expenses or material additional cost.

Page 8

Annex G - Warranty Services

Purchase and License Agreement for FWA Equipment (December 2004)

·	Warranty on FRU repaired by Airspan shall be limited to one hundred and eighty (180) days from delivery of the repaired FRU or to the end of the original warranty period, whichever is longer.

·	The defective FRU returned to Airspan becomes the property of Airspan and, subject to Airspan’ receipt of the defective FRU, its replacement becomes Axtel’s property.

·	Airspan reserves the right to reject the return of any FRU that does not clearly display the specific part request Return Material Authorization (“RMA”) number or does not include the associated completed Airspan fault report forms.

Airspan will from time to time assess Products offered and supported. The assessment will be based on technology, market development, product deployment, and support requirements and may identify certain Products that will be discontinued. Airspan reserves the right to terminate any service purchased by Axtel for products that have been discontinued. Subject to the terms and conditions of the FWA PLA, continued support for any discontinued products beyond the effective date of discontinuance may be provided in accordance with the terms and conditions as stated in the FWA PLA.

·	The service will be furnished by Airspan or a party authorized by Airspan.

As part of the repair service, Airspan will monitor all faulty product returns for No Fault Found (“NFF”) from Axtel. All repair cases resulting in “no fault found” will not be charged to Axtel. In the event that such Product presents again in the field within 180 days of return date the same failures as noticed by Axtel, Airspan shall repair or replace, within 60 days of receipt of the FRU, such Product at its cost and expense.

·	If, in the judgment of Airspan, the returned FRU has been damaged by misuse, accident, modification or failure to maintain the proper physical or operating environment or improper maintenance by Axtel, then Airspan will return the defective un-repaired FRU to Axtel at Axtel’s expense.

·	It is critical that Axtel regularly ship all defective Products to Airspan, as and when defects are detected, to avoid the accumulation of defective Products that will impact Airspan's ability to meet the target turnaround times.

·	In the case of Product replaced at Airspan discretion, and which would be returned with a different Serial Number to Axtel, the proper documentation shall be provided by Airspan for Axtel’s asset controls to evidence which serial number is replaced.

Case Progress Status

Airspan Technical Support use the following status to differentiate the case conditions during the evolution of the case investigation. A set of status, its related meaning and its relationship with the case age, are defined in the table below:

Status	Description	Airspan Clock
Newly Opened	This status is the default. It signifies that no work has been done on the case.	Start
WIP Level 1	This status is used when a NTS Engineer is actively working on the Case.	Not Stopped
WIP Level 2	This status is used when a Second Level Support Engineer is actively working a case * Second Level Support: Software Support, Product Support.	Not Stopped
Escalated To Design	This status is used when a Design Engineer is actively working on the case	Not Stopped

Page 15

Annex G - Warranty Services

Purchase and License Agreement for FWA Equipment (December 2004)

Status	Description	Airspan Clock
Answer From Design	Design Engineer has concluded its investigation and has replied back to the NTS Engineer	Not Stopped
With A Axtel	During the course of conducting their research, the NTS Engineer may need additional information or activity from the Axtel. The "With a Axtel” status is assigned when the NTS Engineer is waiting on a Axtel response in order to continue investigation	Stopped
Interim Solution	If a temporary solution is provided that eliminates Axtels pain until a permanent solution can be delivered, RQMS requirements allow the case to be set to an “IS” status during this window of time if approved by the Axtel. In calculating case age, this interval will be discounted if the permanent fix was delivered on the negotiated commitment date. If the permanent fix does not resolve the reported problem, case status shall be changed to Work in Progress (Level 1 or 2). If the case is returned to a Work in Progress (Level 1 or 2) status after using the IS, the IS time period will be added to the RQMS age of the case.	Stopped
Future Deliverable	Axtel agrees to live with the problem condition and that the fix will be delivered as part of a future Airspan product release (software release, maintenance release, documentation release or hardware revision. Requirements to use this status include Axtel consent; fix identification, and delivery commitment. This status code does not add time to the RQMS age of the case unless the solution fails and the case is moved back to Work in Progress (Level 1 or 2) status. If the case is returned to a Work in Progress (Level 1 or 2) status after using the FD, the FD time period will be added to the RQMS age of the case.	Stopped
Solution Delivered	Solution Delivered or available for testing and verification. If the delivered solution does not resolve the reported problem, the status will be changed to Work in Progress (Level 1 or 2). If the case is returned to a Work in Progress (Level 1 or 2) status after using the SD status, the SD time period will be added to the RQMS age of the case.	Stopped
Pending OEM Vendor	The case has been handed over to an OEM Vendor for resolution	Not Stopped

2.2.7
