Installing a Signaling Server
and TLAN subnets of a CS 1000E and CS 1000M system respectively. It also
contains instructions for connecting a maintenance terminal to the Nortel CP
PM Signaling Server.
The NTDW61BAE5 model of the Nortel CP PM Signaling Server was
designed for use in a CS 1000E system. As such, it is inserted into a slot of
the Media Gateway (MG 1000E or MG 1000B). The Media Gateway also
hosts the Media Gateway Controller (MGC) that has Ethernet ports for
connecting to the ELAN and TLAN subnets of your CS 1000 system.
However, it is common in a CS 1000E system for the Call Server to be
connected to the MGC through these ELAN and TLAN Ethernet ports. If the
Call Server is not connected to the MGC through these Ethernet ports, the
NTDW61BAE5 model of the CP PM Signaling Server uses them to connect
to the ELAN and TLAN subnets of the CS 1000E system. If the Call Server
is using the MGC ELAN and TLAN Ethernet ports, the Nortel CP PM
Signaling Server is connected directly to the ELAN and TLAN Ethernet
switches from the faceplate ELAN and TLAN Ethernet ports.
The NTDW66AAE5 model of the Nortel CP PM Signaling Server was
designed for use in a CS 1000M system. As such, it is inserted into a slot of
a Universal Equipment Module (UEM). UEMs do not have built-in ELAN
and TLAN Ethernet ports. These Ethernet ports must be installed on the back
of the UEM to enable the Nortel CP PM Signaling Server to connect to the
ELAN and TLAN subnets of your CS 1000 system (see Procedure 52:
"Installing ELAN and TLAN Ethernet ports on the back of a CS 1000M
UEM" on page 182.)
Figure 49 shows the faceplates of the two models of the Nortel CP PM
Signaling Server with labeling for all components (NTDW61BAE5 on the
left and NTDW66AAE5 on the right).
