Abstract

Apparatus and method for minimizing a retransmission of signals and messages when an errored message is received during an xDSL negotiation procedure of a communication session. A receiving section monitors received data related to a Frame Check Sequence of an xDSL negotiation procedure. When the receiving section determines that an errored message is received, a retransmission request device transmits a retransmission request message. The retransmission request message indicates which correct message was lastly received. However, if a predetermined number of errored messages occur, the communication session is terminated.
