Route Analysis

The route analysis is a process of table query and data analysis. Figure 1 illustrates the process for analyzing how to route an outgoing call over ISUP trunks.

Failure Source Name and Failure Processing

Failure Source Name

A failure source name denotes the source of a call. The system can perform different failure processing operations based on different call sources. When a call from a certain call source fails, the system can select a corresponding failure processing mode based on the failure source name.

Call Prefix and Dialed Number Set

Call Prefix

A call prefix is a prefix of a called number. It refers to one digit or several sequential digits starting from the first digit of the called number. It can also be equal to the entire called number. In other words, a call prefix is a subset of the called number.

Route Selection Source Name and Route Selection Name

A route selection source name is the name of the classification of the outgoing route selection policy configured for a call source. A route selection source name maps a call source. When different outgoing route selection policies are configured for different subscribers of an MSC, different route selection source names can be defined for different call sources. A route selection source name is configured in the Call Source table (ADD CALLSRC).

Office Direction and Route

Call Source

A call source refers to the subscriber or incoming trunk that originates a call. A call source name is specified for each call source. Generally, there are three types of call sources: A interface, Iu interface, and incoming trunk.

Telnet Command

The Telnet Client command prompt accepts the following commands:

Command	Description
open	Use open hostname portnumber to establish a Telnet connection to a host.
