90 ITG engineering guidelines
IP Trunk 3.01 (and later) is targeted towards the Enterprise customer who
has a Meridian 1/CS 1000M system installed for providing corporate voice
services and an intranet for corporate data services. A customer is expected
to use the IP Trunk 3.01 system to move traffic from a PSTN-based network
to the intranet. Voice and fax services which depended on circuit-switched
and Time Division Multiplexing (TDM) technology are transported using
packet-switched and statistical multiplexing technology.
This chapter provides guidelines for designing a network of IP Trunk 3.01
(and later) nodes over the corporate intranet. It describes how to qualify the
corporate intranet to support an IP Trunk 3.01 (and later) network and how
to determine changes required to maintain the quality of voice services
when moving those services from the PSTN. It addresses requirements for
the successful integration with the customer’s existing LAN. By following
these guidelines, the IP Trunk 3.01 (and later) network can be designed
so that the cost and quality tradeoff is at best imperceptible and at worst
within a calculated tolerance.
Pre-installation analysis of the data network enables IP Trunk 3.0 (and later)
to be provisioned correctly. For proper analysis and deployment, obtain a
network diagram or a description of the network topology and hierarchy.
Nortel recommends using a data network analyzer (for example, Sniffer
TM
)
for evaluation and troubleshooting.
Audience
This chapter is intended for telecom and datacom engineers who design and
install the IP Trunk 3.01 (and later) node portion of the VoIP network. It is
assumed that the telecom engineer is familiar with engineering the Meridian
1/CS 1000 system and obtaining system voice and fax traffic statistics. It is
assumed that the datacom engineer is familiar with the intranet architecture,
LAN installations, tools for collecting and analyzing data network statistics,
and data network management systems.
For information on designing a Meridian 1/ CS 1000 network, refer to the
