334 Provisioning IP Trunk3.01 (and later) in TM 3.1
Figure 129
Example of a complex dialing plan
Gatekeeper-resolved endpoints
The IP Trunk3.01 (and later) application has two methods of resolving
addresses. The IP Trunk 3.01 (and later) node first checks the dialing
plan information using the Address TranslationProtocol Module (ATPM).
If no match exists, the IP Trunk3.01 (and later) node checks to see if a
Gatekeeper has been provisioned. If a Gatekeeper has been provisioned,
the IP Trunk3.01 (and later) node forwards the applicable H.323 messaging
to the Gatekeeper which attempts to complete the call. If a Dialed Number
(DN) does not match what is stored in the local dialingplan, and if there is
no Gatekeeper is provisionedor the Gatekeeper does not know the number,
the call fails.
Zones
A network zone is a logical grouping of CS 1000M systems with IP Peer
H.323 Gateways,IP Line 3.0, IP Trunk 3.01 (and later), and/or third-party
gatewaysor endpoints. Network zones can have geographical significance;
for instance, a company could configure one network zone for its east coast
offices and one network zone for its west coast offices.
Recommendation
Though not mandatory, Nortel recommends that zones be used for IP Trunk
3.01 (and later).
