TMB1PD1 overview

Huawei OSN1800V 32*E1/T1 processing board TMB1PD1.

The TMB1PD1 board is a TDM processing board. When the TMB1PD1 board is used together with the TMB1DMS interface board, 32 E1 or T1 signals can be transmitted and received on the OSN series of equipment.

The TMB1PD1 has no port. The TMB1DMS functions as its interface board and provides signal input and output ports for the TMB1PD1. One TMB1DMS works with two TMB1PD1 to achieve tributary protection switching (TPS) protection.

    The board is good, but the delivery is too slow and the lead time is too long.
