Exhibit 99.1

ASC Reports Fourth Quarter and Full Year Results

Vienna, VA, February 28, 2002 - Advanced Switching Communications, Inc. (NASDAQ: ASCX) today reported its results for the fourth quarter and full year 2001.

For the three months ended December 31, 2001, the Company reported revenue of $0.4 million, a net loss of $17.1 million and a net loss per share of $0.40, compared to revenue of $13.4 million, a net loss of $2.1 million and a net loss per share of $0.05 for the three months ended December 31, 2000.

For the year ended December 31, 2001, the Company reported revenue of $15.5 million, a net loss of $54.1 million and a net loss per share of $1.28, compared to revenue of $37.4 million, a net loss of $14.4 million and a net loss per share of $0.78 for the year ended December 31, 2000.

The net loss for the three months and the full year ended December 31, 2001 includes an $800,000 charge for a reduction in force completed in the fourth quarter and a $6.1 million charge to reflect the impairment of assets in connection with the Company's winding down of operations.

As of December 31, 2001, the Company reported assets totaling $82.9 million, including $77.8 million in cash and marketable securities -- and virtually no debt. At the end of December 2000, the Company reported assets of $137.3 million, including $112.5 million in cash and securities.

In addition, as part of its plan to wind down operations, ASC implemented a 90 percent reduction in its workforce earlier this month. This reduction will reduce the company's expenditures and assist it in its efforts to preserve its cash reserves. ASC expects to incur a charge of approximately $4.0 million in the first quarter of 2002 to cover costs associated with the workforce reduction. In connection with its planned liquidation of net assets, the Company also expects to incur costs of at least $1.5 million that will be recorded as a charge in the first quarter of 2002.

The Company also announced that, on February 21, 2002, a complaint was filed in the United States District Court for the Eastern District of Virginia against the Company and certain of its current and former officer and directors. The plaintiffs in this action claim to own a total of 100 shares and purport to act on behalf of a class of other shareholders. The complaint alleges violations of the federal securities laws in connection with the Company's initial public offering and subsequent public statements. The Company believes the claims asserted in the complaint are without merit and intends to contest these claims vigorously. However, the outcome of the suit cannot be predicted. The existence of these claims could delay the making of any distributions to the Company's stockholders or reduce the amount available for distribution in connection with the proposed plan of liquidation.
