How do I view the status of an ISDN link

Run the display isdn call-info command.

<Huawei>display isdn call-info
Serial1/0/0:15 :
Link Layer: TEI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Network Layer: 0 connection(s)

If the Integrated Services Digital Network (ISDN) link is in the MULTIPLE_FRAME_ESTABLISHED state, the ISDN link is established successfully.
