Step 2 Confirm that the current ISDN switch type matches the actual switch type that you
are using. In the output example, the switch type is “basic-5ess.”
Step 3 Confirm that the “Layer 1 status: ACTIVE” message appears in the command
output. In the output example, the status is “ACTIVE.”
Step 4 Confirm that the “State = MULTIPLE_FRAME_ESTABLISHED” message
appears in the command output. The output example shows this message.
In some cases, you might see a “State = TEI_ASSIGNED” message instead of the
“State = MULTIPLE_FRAME_ESTABLISHED” message. This message also
means that the ISDN line is correctly configured.
Step 5 To continue configuration, reenter global configuration mode.
Tips
If you are having problems, do the following:
• Make sure that you entered the no shutdown command for the ISDN
interface while in interface configuration mode. This enables the
configuration changes that you made on the interface.
• Make sure that any external Network Termination 1 (NT1) equipment is
functioning correctly. Refer to the documentation that came with the NT1.
• Check with the ISDN service provider to make sure that the ISDN line is
correctly configured.
