To verify an ISDN configuration, perform the following tasks:
Display the status of ISDN service on the ISDN interface. For example, you can display ISDN BRI status on the br-6/0/0 interface and ISDN PRI status on the ct1-2/0/0 interface.
From the operational mode in the CLI, enter show isdn status.
user@host> show isdn status
Interface: br-6/0/0 Layer 1 status: active Layer 2 status: CES: 0, Q.921: up, TEI: 12 Layer 3 status: 1 Active calls Switch Type : ETSI Interface Type : USER T310 : 10 seconds Tei Option : Power Up
user@host> show isdn status
Interface: ct1-2/0/0 Layer 1 status: active Layer 2 status: CES: 0, Q.921: up, TEI: 0 Layer 3 status: 8 Active calls Switch Type : NI2 Interface Type : USER T310 : 10 seconds Tei Option : Power Up

The output shows a summary of B-channel interfaces and the active ISDN calls on the interfaces. The first example shows the two B-channels on an ISDN BRI interface—bc-2/0/0:1 and bc-2/0/0:2. The second example indicates B-channels bc-2/0/0:1 through bc-2/0/0:23, the 23 B-channels on an ISDN PRI interface. Determine the following information:
Verify that the dialer interface is correctly configured. To determine the ISDN interfaces on which calls are taking place, see Displaying the Status of ISDN Calls.
