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 the following examples 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 550 is emulating the network on those connections (see Figure

Example 2 Point-to-Point Connection Dial Plan Configuration
In this example, ATLAS 550 A operates as the network while ATLAS 550 B terminates the network. That is, ATLAS 550 A emulates the network and its PRI interface acts as the User termination. The PRI interface of ATLAS 550 B acts as the Network termination (see Figure
