●

The ERM-Mux/plus G64K Tributary Card provides 4 independent G.703 64Kbps Co-directional data channel capability. Each channel

can independently assign any 64Kbps timeslot from the aggregate E1. Individual Shielded RJ-45 connectors that conform to USOC

RJ-48C standard wiring provide the G.703 connections. Standard UTP or alternately shielded UTP are both acceptable cabling media.

These data channels may be linked to multiplexers, terminal equipment or satellite/micro-wave transmission equipment. In

Co-directional signaling, the clock signals are recovered from the received G.703 data stream. Only Tx and Rx pairs or a total of 4 wires

are required in 64Kbps co-directional transmission.

E&M Signaling PBX trunks

Provides E line, M line, SB (battery) and SG (ground) lines

Supports types I, II, III, IV or V

G.711 Codec

LED indicators for Power, Alarm, activity

Hot Swappable

●

The ERM-Mux/plus E&M Voice Tributary Card provides six independent Ear & Mouth Voice channel capability. Each channel can

independently assign any 64Kbps timeslot from the aggregate E1. Individual Shielded RJ-45 connectors provide the voice connections.

Standard UTP or alternately shielded UTP are both acceptable cabling media. These voice channels may be linked to PBX (Private

Branch Exchange) to facilitate voice to voice connections. The channels support selection of Type 1~5, support 2 or 4 wire operation

and have 0.5dB steps for signal attenuation. When using this card, an appropriate voice compatible power module must be used in the

ERM-MUX/Plus.
