Overview
Voice with E&M Signaling Multiplexed onto T1 Wide Area Networks
The T1 MUX E&M has One, two, three, or four E&M balanced 4-Wire 600 ohm Voice Frequency interfaces with Push to Talk Relay transfer signaling that are multiplexed onto a T1 WAN interface.
Interconnect 600Ω analog, audio and intercom devices such as Radio Wireline, FSK modems, E&M, teleprotection relay controllers, etc. and dry contacts over T1 links.
The T1 MUX E&M employs high resolution Analog to Digital circuitry that maintains the quality of the original audio signal. The PCM CODEC converts 600 Ohm Analog Voice Band into Pulse Code Modulated m-Law G.711.
Public Safety Radio Tower Wireline Audio over T1 WANs
A primary application for the T1 MUX E&M is the conversion of Voice Grade E&M circuit interfaces with Push to Talk, that connect Public Safety Radio Base Stations to concentrator hubs.
4-Wire leased line analog networks interconnect VoiceBand Communications for Utilities Municipalities and Public Safety Agencies.
Applications
Leased Line Discontinuation
Many telecom providers are discontinuing their leased lines, such as Verizon and AT&T, and now offering T1 services as an alternative. When T1 lines are available, the T1 MUX VF can seamlessly provide a solution.
