CREATING DIAL PLANS—EXAMPLES
The ATLAS
Dial Plan
acts as the numbering plan for switched connections.
This menu defines to ATLAS the phone numbers and features associated
with dual-tone-multifrequency (DTMF) dialing, Primary Rate ISDN (PRI),
and Basic Rate ISDN (BRI). To operate as a switch, ATLAS must be able to
terminate Network connections (Network terminations) and emulate the net-
work onto other termination equipment (User terminations).
Understanding Dial Plan Configurations
Understanding Dial Plan configurations results in the successful creation of
a switched connection. This understanding includes determining which of
the connections are acting as Network terminations and which are acting as
User terminations. Use Examples 1 and 2 to help clarify the definitions for
these two types of terminations.
Example 1
PSTN Connection Dial Plan Configuration
In this example, access to the PSTN is provided by a single PRI line. There-
fore, this line is configured as a Network termination. The remaining cir-
cuits, which feed various types of switched equipment, are configured as
User termination because ATLAS is emulating the network on those connec-
tions (see Figure 9-3).
