The TC8612 offers a simple and effective method to transport dry contacts over T1/E1 replacing complex T1/E1 channel banks for small scale applications and providing a plug and play solution.
It is economical, simple to install and comes standard with built-in power redundancy and extensive diagnostics.
Diagnostics include DIP switches for Local & Remote Loopback and other application configuration switches. Each unit also provides multiple LEDs for Alarm, Power, Vcc, T1/E1 Status, and RLY & DET status LEDs for each channel.
