TC8714-2
4-Wire E&M Analog & Dry Contact Gateway Channel Bank
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
