7-8 E&M Ports
Model No.
Running Head
STATE
The State setting determines whether the port is active or inactive. An inactive port does not
occupy a time slot on a WAN link. 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. When choosing the
type of wan, you must also select the desired port of the WAN or OWAN port for transmission
over the T1 or E1 link.
It is not necessary to assign all E&M ports to the same WAN or OWAN link, nor to contiguous
time slots on a WAN or OWAN link.
TS
The TS setting identifies the time slot on the WAN link to which this port is assigned. Values
range from 1 to 24 for T1 links, and 01 to 31 for E1 links. For a display of the available time
slots, refer to the cross-connect map for the WAN link; see Chapter 4, System Configuration
and Operation in the System Reference Guide for information about viewing cross-connect
maps.
MODE
The Mode setting specifies whether or not a port uses E&M signaling, or if it operates in the
Transmission-Only (TO) mode. Use the to mode if you are connecting the port to a four-wire,
dedicated-line modem that does not require E&M signaling. Use e&m I, e&m II, e&m IV or
e&m V, depending on the type of e&m signaling desired. When choosing an E&M signaling
mode, all ports using E&M must use the same mode.
Rx TLP
The Receive Transmission Level Point (TLP) setting controls the amount of gain or loss added
to a signal after it is decoded to analog. To increase the signal level, set the Rx TLP field to a
positive number (i.e., the larger the number, the more gain is added). To decrease the signal
level, set the Rx TLP field to a negative number (i.e., the more negative the number, the more
the signal level is decreased). For example, an incoming signal at -5 dBm can be increased to
-2 dBm by setting Rx TLP to +3 dB. The Rx TLP range is -16.3 dB to +7.5 dB.
