WAITING TIME GITTER DROPPING CIRCUIT OF SYNCHRONOUS MULIPLE APPARATUS

摘要

The circuit decreases waiting time jitter generated in a reverse mapping unit during stuffing. The circuit includes a line driving unit (15) for transmitting and for receiving DS3 asynchronous signal, a stuffing and synchronizing unit (1) connected to the line driving unit to map DS3 asynchronous signal to VC32 signal, a de-stuffing and reverse-synchronizing unit (18) connected to the line driving unit to map VC32 signal to DS3 asynchronous signal, and an interface unit (17) for supervising the stuffing and synchronizing unit (1) and the de-stuffing and reverse-synchronizing unit (18).
