Generalized route selection

Issue 5 October 2002 1689555-233-506

Example

Assume a route pattern is set up with BCC 0 and BCC 2 set to yes in preference 1,

and BCC 1, BCC 3, and BCC 4 set to yes in preference 2.

A voice or Mode 2 data call accessing this pattern uses preference 1. A Mode 1,

Mode 3, or Mode 0 data call uses preference 2, regardless of what trunks are

available in the first preference.

Data modules and GRS

For all endpoints, the switch automatically determines its current operating mode

when a data module begins operations. The default is Mode 2.

Because call origination from a data module determines the mode used on the call,

you should press the Originate/Disconnect button if you change data options. This

way, the right mode is assigned to the next call.

Table 57 lists the BCC for different types of information and endpoints.
