Method and apparatus for adjusting channel insertion timing

摘要

An information communication system having a plurality of terminal equipment units, a network termination unit, a receive (R) line, and transmit (T) line. The terminal equipment units are commonly connected to the R and T line so as to communicate with the network termination unit. The communication is achieved in the form of successive frame signals, each composed of at least successive channels. Each terminal equipment determines a delay time for channel insertion into the frame signal on the T line. the delay time is determined during a learning identification algorithm operation which takes the transmission delay time along the R and T lines into consideration.
