Define the dialing plan information 333
Gatekeeper-resolved endpoints
The IP Trunk 3.01 (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 Translation Protocol Module (ATPM).
If no match exists, the IP Trunk 3.01 (and later) node checks to see if a
Gatekeeper has been provisioned. If a Gatekeeper has been provisioned,
the IP Trunk 3.01 (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 dialing plan, and if there is
no Gatekeeper is provisioned or 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
gateways or 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).
In the TM 3.1 Navigator window, the Gatekeeper zone can be found by
left-clicking on the CS 1000M system, selecting Properties, and clicking on
the Network tab. See
Figure 130 "Making a Gatekeeper zone" (page 334) .
When provisioning the applicable devices in TM 3.1, use network zones
to coordinate the Gatekeeper information. The Gatekeeper zones were
defined on the CS 1000M. For information on configuring zones on the CS
1000M systems, see IP Peer Networking Installation and Commissioning
(NN43001-313).
