Introduction
The TIEL board (tie line E & M) provides four analog tie trunk circuits for E&M signaling for Hicom 150 E OfficePro. The circuits can be configured for one- or two-way operation. They convert incoming analog signals into PCM (pulse-code modulation) signals and convert outgoing PCM signals into analog signals for tie-trunk traffic.
Speech Paths
The speech paths can be set to four-wire or two-wire mode. Four-wire connections should be used for high transmission quality on analog networks (this description deals only with four-wire mode).
The advantage of separate speech paths for the incoming and outgoing directions is that the stability (echo) of a connection is not adversely affected. In addition, repeaters in the transmission equipment compensate for attenuation loss on the line.
E&M Signaling Paths
The E&M signaling paths carry the signals that control connection setup and cleardown. Various interfaces can be selected, depending on the requirements of the remote system or transmission equipment. These interface types have different numbers of wires and different potentials.
Starting Up a Tie Trunk
Before you can start up a tie trunk, you must determine the type of interface supported by the two systems. Type 2 is preferable because it virtually excludes problems with longitudinal voltages.
