TC3846-6

2W/4W E&M 600 Ohm and Dry Contact over IP Gateway

TC3846-6
Rollover or Touch for Expanded View. Scroll to Zoom.

Features

The TC3846-6 links or extends up to 4 channels of 600 ohm 2/4-wire analog and dry contacts across Layer 2/3 Ethernet/IP, CE, or MPLS networks. For cost savings and scalability, units can be ordered with only 1 or 2 channels of analog and dry contacts and later expanded in the field to 2 or 4 channels.

  • 1, 2, 4 channels (expandable) of 2W/4W E&M 600 ohm over IP
  • Uncompressed audio ensures flat audio response allowing crystal clear audio and 100% passing of in-band audio signaling
  • Extremely low latency ensures compatibility with all voting and simulcast systems
  • Compatible with all dispatch consoles
  • FSK, FFSK modem capability
  • Meets or exceeds IEC 61850-3, IEEE 1613 & NEMA TS-2 standards
  • Extreme operating temp (-40°C to +80°C) option
  • Member of JumboSwitch Product Family

How it's connected:

Here is a typical application radio system - simulcast with dispatch and voter

Analog & Dry Contact over IP with voter/comparator application

The JumboSwitch series is a TDM over IP/Ethernet based solution designed to emulate time-division multiplexing over packet switched networks (PSN). TDM over IP/Ethernet is a TDM pseudowire (PW) technology making it possible to provision E1, T1, E3, T3, STS-1 and serial data services across PSN's such as IP, MPLS or layer 2 Ethernet Networks.

"Over the past thirty-five years I have used similar boxes from other vendors for similar applications. But I have never seen one that would produce such a linear, uniform audio transmission from one end to the other - especially across an IP link."
- Martin T. Vinson, N.C.T., A.S.C.E.T.

Applications

Radio system using Simulcast with dispatch and voter

A typical radio system in a simulcast voting network. Using a TC3846-6 at each of the remote sites, 4W from these sites are converted and sent back to dispatch through a packet-based network, then converted back to 4W to communicate with the voter and dispatch console. A single card at dispatch can communicate with up to 4 remote locations.

Typical radio system simulcast application

Broadcasting in a campus security or Public Address (PA) network

The TC3846-6 can also take 1 input and broadcast by cloning the signal over its other open ports, ideal for PA networks that are looking to migrate their transport to a packet-based network.
