Apparatus for implementing the function of a virtual container-11 and a tributary unit group-2 in a synchronous digital hierarchy |
摘要 |
An apparatus for implementing the integrated function of virtual container-11(VC-11) and tributary unit group-2(TUG-2) is configured to transmit and receive a DS-1 network signal and a TUG-2 system signal through a synchronization process in a synchronous multiplexing structure. Data between a network and a system is converted by using only one Tx buffer and one receiving buffer in a transmitter and a receiver respectively. An input of a Tx FIFO buffer is a DS-1 signal of 1.544 Mbps, and an output thereof is a TU-11 frame of 1.728 Mbps including spaces for a path overhead and a pointer. An input of a RX FIFO buffer is the TU-11 signal of 1.728 Mbps in which the path overhead and the pointer are eliminated, and an output thereof is the DS-1 signal of 1.544 Mbps.
