System requirements

Note: In this document, TLAN refers to the Telephony LAN that
transmits the ITG voice and fax traffic. ELAN (Embedded LAN) refers
to the management and signaling LAN for the system site.
IP Trunk 3.01 (and later) depends on the managed IP network, not the
internet, because the managed IP network can provide adequate latency,
jitter, and packet loss performance to support VoIP with an acceptable voice
quality.
The Media Card 32-port trunk card and the ITG-Pentium 24-port trunk cards
are able to reside in any of the following Meridian 1/CS 1000M systems
running CS 1000 Release 4.0 software:
• Small Systems
• Large Systems
IP Trunk 3.01 requires OTM 2.1 (and later).
Customers must have the NTAK02BB (minimum vintage) SDI/DCH card
(Small Systems) 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. Earlier vintages are not supported, as the level of
MCDN functionality required to support ITG-compatible ISL is not available
on earlier vintages.
Install a modem router on the ELAN subnet to provide remote support access
for IP Trunk 3.01 (and later) 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.
