Using ISDN

When you have ®nished con®guring the ISDN interface, you can use thelist command to display your con®guration.

Con®guring the ISDN Interface

T1/J1 PRI Interface

Specify the following T1/J1 parameters:

1.For the T1/J1 PRI interface, line build out speci®es the attenuation of the signal transmitted by the router's T1 port. Specify the lbo (line build out) based on the information provided by the service provider.

a= -00.0 dB b= -07.5 dB

c= -15.0 dB

d= -22.5 dB

For example:

set int lbo a

2.Specify the code, either B8ZS or AMI. B8ZS is default. The service provider provides this information.

For example:

set int code AMI

3.Specify ZBTSI- Zero Byte Time Slot Inversion, either ENABLED or DISABLED. The default is DISABLED. The service provider provides this information.

For example:

set int ZBTSI enabled

4.Specify the esf-data-link. Select one of the following based on the service subscription:

ANSI-T1.403 ANSI-IDLE AT&T-IDLE

Default is ANSI-T1.403

For example:

set int esf-data-link ansi-idle

E1 PRI Interface

For the E1 PRI interface, specify the following parameters:

1.Specify the code, either HDB3 or AMI. HDB3 is default. The service provider provides this information.

For example:

set int code HDB3

2.Specify the crc4, either ENABLED or DISABLED. Default is ENABLED. The service provider provides this information.

For example:

set int crc4 enabled

Adding Dial Circuits

Dial circuits are mapped to ISDN interfaces. You can map multiple dial circuits to one ISDN interface.
