ITG Trunk 2.0 ISDN Signaling Link (ISL) Description, Installation and Operation
System requirements
ITG is available for Meridian 1 options 11C, 11C Mini, 51C, 61C, 81 and 81C
systems running X11 release 25 or later software. See Table 1, “Software
packages for Meridian 1 ITG ISL Trunk,” on page 22 for required software
packages.
ITG requires MAT 6.6 or later including Alarm Management. MAT Common
Services include the Meridian Internet Telephony Gateway applications.
Customers must have the NTAK02BB (minimum vintage) SDI/DCH card
(Option 11C) or MSDL card (Large Systems) for ISDN Signaling capability.
If the customer does not have either of these cards, or does not have an
available DCH port on them, the customer must order these cards to support
ISDN functionality.
A modem router must be installed on the E-LAN in order to provide remote
support access for ITG Trunk and other IP-enabled Nortel Networks
products. The Nortel Networks Netgear RM356 modem router integrates the
functions of a V.90 modem, a PPP remote access server, an IP router, and a
4-port 10BaseT Ethernet hub, and provides a range of security features that
must be configured to comply with the customer's data network security
policy. The Netgear RM356 modem router can be ordered through many
electronic equipment retail outlets.
Customers with ITG Trunk 1.0 Basic Per Trunk Signaling 8-Port ITG trunk
cards have the option of upgrading to ITG Trunk 2.0 ISDN Signaling trunks.
Port capacity remains 8 ports per card. 8 and 24-Port cards can be mixed in
the same ITG ISL Trunk node. The section “Upgrade an ITG Trunk 1.0 node
to support ISDN signaling trunks” on page 235 describes the upgrade.
