Hi Aamir,
Let me try a blank shot just to give you a pointer. Last time I solved a
similar problem, I painfully searched the docs in vain for clues
Check if you have to explicitly assign an SPID. If you did, then remove or
add the leading numbers; or maybe the SPIDs you assigned are too long; or
maybe the SPIDs and the dial numbers don't agree.
Alternatively, play with "isdn switch-type basic-net3", where you don't need
SPIDs - if your simulator allows that. With this switch-type, your simulator
will give you the error when the dial number you assign is too long (3-digit
numbers should be OK - I use the simulator "vconsole").
On another instance, this time on a live network, it turned out that the
pervice provider assigned a point-point line to us (or so he said), so I
couldn't dial. And if I did, then I got the "Unfound B-channel" error.
BTW, ISDN is not on the CCIE RS Lab blueprint anymore :-)

Hi there ppl,
I just bought one ISDN simulator, connected two routers, but on one router
when i do debug it gives me when i ping the remote router:
Success rate is 0 percent (0/5)
AMW#
*Mar 1 01:07:08.379: ISDN BR0 Q931: TX -> RELEASE pd = 8 callref =

Cause i = 0x8090 - Normal call clearing *Mar 1 01:07:08.403: ISDN
BR0 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x93 *Mar 1 01:07:08.427:

*Mar 1 01:06:38.467: ISDN BR0 **ERROR**: host_disconnect: isdn_info NULL on

What is this Unfound B-channel? Could this be a simulator problem. Any
response is appreciated.....
Thanks
Aamir
