64 System description
For further information on ISDN Signaling Link (ISL), refer to System
Management Reference (NN43001-600), ISDN Primary Rate Interface
Installation and Commissioning (NN43001-301), and ISDN Primary Rate
Interface Maintenance (NN43001-717).
Inter-card signaling paths
The Leader, DCHIP, and Follower cards communicate using their ELAN
network interface IP addresses.
Figure 19 "IP Trunk 3.01 (and later) card
signaling paths" (page 64) illustrates the IP signaling paths used inter-card
and between the cards and the system in the ITG offering.

IP Trunk 3.01 (and later) card signaling paths
In Figure 19 "IP Trunk 3.01 (and later) card signaling paths" (page 64) ,
the DS-30X connection is part of the IPE shelf’s backplane. The ISL DCH
connection is a cable that runs from the "octopus" breakout cable, on
the back of the IPE cabinet, to one of the MSDL’s RS-422 ports. The
Leader/Follower card messages normally travel over the TLAN subnet. The
DCHIP messages travel over the ELAN subnet - a 10BaseT LAN connected
to each IP trunk card and the TM 3.1 PC. A separate 10/100BaseT LAN
transmits the voice/fax data to the remote VoIP systems.
Dialing plans
Dialing plan configuration allows customers to set up routing tables to route
calls to the appropriate destination, based on dialed digits. The dialing plan
is configured through the Electronic Switched Network (ESN) feature, using
