ISDN Commands
11-90 ISDN BRI and PRI Commands
Example
The following example selects a switch type on the BRI 1/1 interface:
XSR(config)#interface bri 1/1
XSR(config-if)#isdn switch-type basic-net3
leased-line bri
This command sets up an ISDN BRI port for leased‐line operation. Leased‐line service at 64 or 128
kbps via BRI is provided in Japan and Germany. The 56 and 112 kbps speeds are provided for
eventual North American deployment of this service.
Once a BRI interface is configured for access over leased lines, it is no longer a dialer interface, and
signaling over the D‐channel no longer applies. Although the interface is called interface BRI, it is
configured as a synchronous serial port and all serial port commands are available.
This command creates a serial interface that is configured as a standard serial port. It can be issued
once for speeds equal to and higher then 112 as both B‐channels are bound to the created serial
interface. For 56 and 64 bps speeds, the command can be issued twice to create individual serial
interfaces :1 and :2 for B1 and B2, respectively.
After you enter the command, you must exit BRI configuration mode and configure the channels
by entering
interface bri [board/port:1] or interface bri [board/port:2] . These Bearer
ports are configured as regular synchronous serial interfaces.
Syntax
leased-line bri speed {56 | 64 | 112 | 128 | 144}
Syntax of the “no” Form
The no form of this command cancels leased‐line BRI by deleting the earlier created serial interface
and returning to the basic‐net3 ISDN switch‐type:
no leased-line bri
Default
CMD/switch type basic‐net3
Mode
BRI Interface configuration: XSR(config-if)#
Note: The shutdown/no shutdown channel commands are overridden by the interface bri
shutdown/no shutdown commands.
56 | 64 Two streams are supported, one on each B‐channel.
112 | 128 |144 One stream is supported over the bonded B1 + B2 or B1+ B2 + D‐
channels.
