E&M Special Services (E&M) Plug-in Card

SKU: 0110-0238 Category:

The Tellabs 1000 MSAP E-lead and M-lead signaling (E&M) plug-in card is a special services channel unit. The E&M card supports one subscriber line circuit for E&M types I, II, III, IV and V and two subscriber line circuits configured for operation in E&M types I or V. The special services plug-in card also supports DX signaling (switched or fixed bias) and can provide subscriber line circuits for Tandem modes I and II (switch and station side) and Pulse Link Repeater (PLR) types I and II.

Flexible

The E&M plug-in card can provide either 2- or 4-wire service. It can only provide 4-wire service when provisioned in the Tandem or DX modes. The E&M plug-in card has a fixed impedance of 600 ohms. Voice frequency gain is provisionable in 0.1 dB increments.


Many uses

This special services card has expanded functionality with additional support for equalization and signaling, and is fully GR-57 compatible. The primary application for the E&M card is interoffice trunking from a PBX to a switch.
