The IDM 120PD provides mutual backup transmission services for dual E1 interfaces, suitable for applications where critical services are transmitted through two different E1 channels.

The IDM 120PD adopts a dual-E1 dual-transmit with best-signal selection mode to select the output E1. The device monitors the line status of both E1 interfaces in real time and selects the optimal output based on the line bit error rate.

This device can transmit various 64K or N*64K services.
