Nortel Networks SRG 50 NN43001-307 - Manual (Page 133)

Network using Uniform Dialing Plan 133
In a typical network, a full region uses a single Home Location Code
(HLOC). However, it is also possible, where the number of users requires it,
to have two or more codes, although using one for the main office and one
for each branch office is unlikely at best.

Scenario 1: UDP throughout the network
Common details
In general, if an HLOC is shared between two or more systems, the
provisioning at the main office gets more complex, unless all branch offices
share HLOC with the main office. That is, if the main office has two or more
HLOC, and one or more of these (but not necessarily the same one) is used
by every branch office, then provisioning is relatively straight forward.
Table 10 "Configuration details for the general case" (page 133) describes
the network configuration and the steps that a call takes during its setup.
