Dial Plan
Configuration
You configure the dial plan after you install the VTL license. See “
License
Installation” on page 81 for information about VTL licenses.
To configure the dial plan for VTLs, you must define:
■ Routes within the dial plan
■ Digit sequences to be used to select those routes
■ Operations to be performed for each route
Example: Dial Plan with Site-Unique Extensions
In Figure 8
, each of the three sites uses a unique extension range. In the
Internal table in the Chicago system dial plan, the entries shown in
Figure 10
control the routing of calls if a user dials an extension in the
2000 through 2999 range (Atlanta extensions) or the 3000 through 3999
range (Dallas extensions) respectively. The dial plans for the Atlanta and
Dallas NBX systems would contain similar, but not identical entries.
An explanation of each line in the dial plan follows Figure 10
.
