Creating a Dial Plan
OVERVIEW
The ATLAS Dial Plan acts as the numbering plan for switched connections. This
menu defines to ATLAS the phone numbers and features associated with dial-up
ports. ATLAS supports Robbed Bit Signaling (RBS) T1 interfaces using DTMF
dialing, Primary Rate ISDN (PRI) and Basic Rate ISDN (BRI). In order to operate
as a switch, ATLAS must be able to terminate network connections (Network Ter-
minations) and emulate the Network into other termination equipment (User Ter-
minations).
Understanding the Application
In order to create a switched Dial Plan successfully, the topology of the configura-
tion must be understood. First you have to understand which of the connections
are acting as Network Terminations and which are acting as User Terminations.
The examples provided in Figure 7-1 and Figure 7-2 are used to clarify these defi-
nitions:
