Example: Adding an ISDN BRI Interface

In this example, you create the br-1/0/3 ISDN BRI interface and add the isdn-dialer-options dialer pool to the interface. You set the pool’s priority to 255. When configuring ISDN BRI properties, you set the calling number to 18005555555, the SPID to 00108005555555, the static TEI value to 23, and the incoming called number to 18883333456. Additionally, you set the ISDN switch type to ATT53, the Q.931 timer to 15 seconds, and you configure the TEI to negotiate with the ISDN provider when the device is powered on.

To configure an ISDN BRI network interface:

1. Create an ISDN interface.

   [edit]user@host# edit interfaces br-1/0/3

2. Configure the dialer pool.

   [edit interfaces br-1/0/3]user@host# set dialer-options pool isdn-dialer-group priority 255

3. Configure the ISDN BRI properties.

   [edit interfaces br-1/0/3]user@host# set isdn-options calling-number 18005555555user@host# set isdn-options spid1 00108005555555user@host# set isdn-options static-tei-val 23user@host# set isdn-options incoming-called-number 18883333456

4. Select the ISDN switch type.

   [edit interfaces br-1/0/3]user@host# set isdn-options switch-type att5e

5. Specify the Q.931 timer interval.

   [edit interfaces br-1/0/3]user@host# set isdn-options t310 15

6. Specify when the TEI negotiates with the ISDN provider.

   [edit interfaces br-1/0/3]user@host# set isdn-options tei-option power-up
