PDH multiplex by bit can adiust the transmitting code and filling code of VI bit to guarantee the second rate of 8 848 Kb/s,But the bogus out of synchrony appears.It will lose many messages and will disadvantage the remultiplex of connecting node,for the receiver firstly researches synchronously,and then makes the basic rate synchronous.To solve the abuse of multiple by bit,this article brings forward the project of PDH multiple.In this project,the message is transmitted by route.It will better fit the switching and multiplexing of message in high rate.And at the same time,it brings much more convenience for synchronousness of both sides.
