Telecommunication systems

摘要

A telecommunication system ( 1 ) provides bi-directional communication between TDM signals on one side and ATM signals on the other. An ATM aggregate ( 10 ) receives and transmits ATM signals, and a TDM interface ( 2 ) receives and transmits TDM signals. A format converter has an ATM bus ( 9 ) and a TDM bus ( 4 ) connected to their respective interfaces. Service-specific adapters ( 5 - 8 ) are connected between the buses.
