System and method for extending the ITU Q.922 LAPF virtual circuit disconnect logic to prevent unsynchronized virtual circuit establishment

摘要

A system and method for extending and modifying the ITU Q.922 LAPF disconnect logic to remedy or alleviate unsynchronized virtual circuit establishment instances between a first device and a second device are disclosed. The method generally includes transmitting a disconnect request message to the first device in response to a data link establish request and transmitting a request for connection to establish link message to the second device upon one of expiration of an awaiting-response timer, receiving a disconnect mode message from the second device and receiving an acknowledgement message from the second device.
