Configures the Isdn Pri controller

© 2004 Cisco Systems, Inc. All rights reserved. bcran v2.1—6-5

Use the isdn switch-type command to specify the CO PRI switch to which the router connects. With Cisco IOS Release 11.3(3)T or later, this command is also available as a controller command to allow different switch types to be supported on different controllers. If configured as a global command, the specified switch type applies to all controllers, unless a switch type is specifically configured on an individual controller.

An incompatible switch selection configuration can result in failure to make ISDN calls. After changing the switch type, you must reload the router to make the new configuration effective.

Telco isdn switch-type commands are shown in the table below. isdn switch-type Command

Unlike BRI operation, ISDN PRIs do not use SPIDs. Therefore, there is no requirement to configure SPIDs, regardless of the ISDN switch type used by the PRI.

Use the controller {t1 | el} slot/port command in global configuration mode to identify the controller to be configured. Use a single unit-number to identify the AS5000 Series controller. These commands are shown in the table below.
