Chapter 7 E&M Ports 7.1 Introduction This chapter provides information regarding the configuration and troubleshooting for the E&M Voice Circuits. The E&M ports manage the flow of toll-grade voice traffic through the IMACS-200 system. Each port encodes an analog (voice, VF) signal to a digital bitstream at the local integrated access system for transmission over a T1 network. Each port also decodes the digital signal to analog at the remote system.
Model No. Running Head Type I signalling is achieved by connecting a ground on the SG lead. Type I E&M signalling is then achieved by operating the E and M leads to achieve off-hook and on-hook signals.Figure 7-1 illustrates a typical Type I interface. Figure 7-1.
Figure 7-2 illustrates a Type II E&M signaling interface where the connecting equipment (normally a PBX or other inter-office carrier systems) originates on the M-lead. The connecting equipment provides a contact closure between the M and SB leads at the interface to send an 0ff-hook (originate) and an open between the M and SB leads at the interface to send an on-hook.
Model No. Running Head Type IV E&M is arranged exactly like Type II E&M, except that a mechanical relay is used for the M relay as in Type I E&M, see Figure 7-3. Figure 7-3.
Type V is symmetrical and allows two signaling nodes to be connected back-to-back, as illustrated in Figure 7-4. This is the most common interface type used outside of North America. Type V uses two leads for supervisor signaling: E, and M. During inactivity the E-lead and M-lead are open. The PBX (that acts as trunk circuit side) connects the M-lead to the ground in order to indicate the off-hook condition.

Set this field to stdby (standby) for ports that will not be used or that are not yet configured. Or, set it to actv (active) for ports that are ready for use. WAN The WAN setting identifies the WAN or OWAN link assigned to this port.
Tx TLP The Transmit TLP setting controls the amount of gain or loss added to the voice signal coming in from the local CPE before it is encoded to digital PCM. To increase the incoming signal level, set the Tx TLP field to a negative value (i.e., the more negative the number, the more gain is added). To decrease the signal level, set the Tx TLP setting to a positive number (i.e., the more positive the number, the more the signal level is decreased).
