Activation of multiple xDSL modems with half duplex and full duplex procedures
Abstract
Method for terminating a startup session of a full duplex or half duplex communication to be established between a central terminal and the remote terminal. When predetermined data is transmitted upon reception of an ACK message transmitted by one of the central or remote terminals, a data transmission in the startup session is suspended. If the other one of the central or remote terminals receives the predetermined data and thereafter detects a predetermined period of silence, the startup session is terminated.
