Chapter 7 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:
