ACC Corp.
400 West Avenue
Rochester, New York  14611

Ladies and Gentlemen:

          We have acted as counsel to ACC Corp., a Delaware corporation
(the "Company"), in connection with a Registration Statement on Form S-3,
as amended (the "Registration Statement"), filed by the Company with the
Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as amended (the "Act"), relating to the issuance and sale by
the Company of up to 1,227,753 shares of Class A Common Stock of the
Company, $.015 par value per share (the "Common Stock").

          This opinion is being delivered to you in connection with the
Registration Statement.

          In connection with the foregoing, we have examined the
Registration Statement and the Preliminary Prospectus contained in the
Registration Statement (the "Preliminary Prospectus").  We also have
examined originals or copies, certified or otherwise identified to our
satisfaction, of such corporate records, certificates and other documents
and have made such investigations of law as we have deemed necessary or
appropriate as a basis for the opinions expressed below.

          As to questions of fact material to our opinions expressed
herein, we have, when relevant facts were not independently established,
relied upon certificates of, and information received from, the Company
and/or representatives of the Company.  We have made no independent
investigation of the facts stated in such certificates or as to any
information received from the Company and/or representatives of the Company
and do not opine as to the accuracy of such factual matters.  We also have
relied, without investigation, upon certificates and other documents from,
and conversations with, public officials.

          In rendering the following opinions, we have assumed, without
investigation, the authenticity of any document or other instrument
submitted to us as an original, the conformity to the originals of any
document or other instrument submitted to us as a copy, the genuineness of
all signatures on such originals or copies, and the legal capacity of
natural persons who executed any such document or instrument at the time of
execution thereof.

          Members of our firm involved in the preparation of this opinion
are licensed to practice law in the State of New York and we do not purport
to be experts on, or to express any opinion herein concerning, the laws of
any other jurisdiction other than the laws of the State of New York, the
laws of the United States of America and the General Corporation Law of the
State of Delaware.

          Based upon and subject to the forgoing, and the other
qualifications and limitations contained herein, and after (a) the
Commission shall have entered an appropriate order declaring effective the
above-referenced Registration Statement, as amended, (b) the shares of
Common Stock have, if required, been duly qualified or registered, as the
case may be, for sale under applicable state securities laws, (c) the Board
of Directors of the Company has approved the issuance and delivery of the
Common Stock in accordance with the provisions of the Underwriting
Agreement, the proposed form of which has been or will be included as
Exhibit 1.1 to the Registration Statement, as amended, and (d) the Common
Stock has been appropriately issued and delivered in accordance with the
provisions of such Underwriting Agreement, and the consideration therefor
shall have been received by the Company, we are of the opinion that the
1,227,753 shares of Common Stock to be offered pursuant to the Preliminary
Prospectus will have been duly authorized and validly issued and will be
fully paid and non-assessable.

          We hereby consent to the filing of this opinion as an exhibit to
the Registration Statement and to the use of our names as it appears under
the caption "Legal Matters" in the Preliminary Prospectus.  In giving such
consent, we do not thereby admit that we come within the category of
persons whose consent is required under Section 7 of the Act or the rules
and regulations of the Commission thereunder.

          We further consent to the filing of this opinion as an exhibit to
applications to the securities commissioners of the various states of the
United States, to the extent so required, in connection with the
registration of the shares of Common Stock.

          This opinion is intended solely for your benefit in connection
with the transactions described above and, except as provided in the two
immediately preceding paragraphs, may not be otherwise communicated to,
reproduced, filed publicly or relied upon by, any other person or entity
for any other purpose without our express prior written consent.  This
opinion is limited to the matters stated herein, and no opinion or belief
is implied or may be inferred beyond the matters expressly stated herein.

                                   Very truly yours,


                                   Nixon, Hargrave, Devans & Doyle LLP
