debug isdn

     Show ISDN related events, I/O message, trail information of Q931 or Q921 message. Using “no debug isdn” stop to show information.

      [no] debug isdn [event | packet | q921| q931]

parameter:

event

trail information of ISDN events

packet

ISDN input/output message 

q921

ISDN trail informatin of   Q921 message

q931

Trail information of ISDN Q631 message

command mode:

supervisor mode

explanation:

     After open ISDN debug switch, it will output ISDN event, original I/O message,trail message of Q931 or Q 921 message, and it can help user to diagnose

ISDN trouble.

Example:

      The following example will introduce conditions of debugging ISDN original I/O    message:

Router#debug isdn packet

ISDN BRI0/3: TX -> packet,  length=8

          fc ff 03 0f 61 28 01 ff

Router#show isdn status

Global ISDN Switchtype = basic-5ess

ISDN BRI0/3 interface :

    Layer 1 Status:

        ACTIVE

    Layer 2 Status:

        TEI = 89, State = MULTIPLE_FRAME_ESTABLISHED

The second layer is in multiple frame-established state.

No Active Layer 3 Call(s)

There are no active calls on layer 3.

Activated dsl 0 CCBs = 0

Activated DSL is 0, and allocated CCB number is 0.

Total Allocated ISDN CCBs = 0

All allocated CCB number are 0.
