Features

The TC8714-2 is a 2-channel 2-/4-Wire E&M Gateway Channel Bank that allows network managers the flexibility of leveraging their existing T1/ E1 circuits by adding low cost analog or dry contact links as needed. It is economical, simple to install and comes standard with built-in power redundancy.

A low cost and immediate solution, the TC8714-2 is typically used to link or extend various 600 Ohm analog, audio and intercom devices (e.g. FSK modems, E&M, teleprotection relay controllers, etc.), and dry contacts over existing T1/E1 links.

  • Up to 2-ch 600 Ohm Analog & Dry Contact
  • 2-Wire or 4-Wire Analog
  • ESF/SF Framing Support for T1
  • PCM30/PCM30C Framing Support for E1
  • Very Low Latency
  • Dry contact detectors with Isolated Ground
  • Compatible with all dispatch consoles
  • Built-in Power Redundancy
  • Rackmount or Standalone
  • Extreme temp (-40°C to +80°C) optional

Applications

The primary use of the TC8714-2 is for the replacement of exisiting channel banks.

The TC8714-2 is specifically designed for remote sites with limited connectivity and providing a simple and cost effective solution
