I need some help:
I have to configure 3 BRIs to work together as a DDR backup for a leased-line, so a maximum of 384Kbps. The chasis is CS 2620, IOS is c2600-js-mz.121-10a. It looks line the ISDN is not brought up by the Diaer1 interface:
ISDN BRI1/2: isdn_is_bchannel_available: No Free B-channels
ISDN BRI1/1: isdn_is_bchannel_available: No Free B-channels
ISDN BRI1/0: isdn_is_bchannel_available: No Free B-channels
The ISDN lines have been tested and confirmed OK by the telco provider.
However, sh isdn status looks like foll:
lmil055#sh isdn sta
Global ISDN Switchtype = basic-net3
ISDN BRI1/0 interface
dsl 8, interface ISDN Switchtype = basic-net3
Layer 1 Status:
DEACTIVATED ????????????????????????
Layer 2 Status:
Layer 2 NOT Activated
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 8 CCBs = 0
The Free Channel Mask: 0x3 ???????????????????????
Number of L2 Discards = 0, L2 Session ID = 239
while the one that is NOT configured looks like:
ISDN BRI1/3 interface
dsl 11, interface ISDN Switchtype = basic-net3
Layer 1 Status:
DEACTIVATED
Layer 2 Status:
Layer 2 NOT Activated
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 11 CCBs = 0
The Free Channel Mask: 0x80000003 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Number of L2 Discards = 0, L2 Session ID = 0
Total Allocated ISDN CCBs = 0
When statring debug isdn q921/931/events and calling the ISDN numbers, it looks good, but the call is cleared, as it is voice. This seems normal.
Anyone, any ideas??? Thanx in advance for a hint.

The "sh isdn status" output would lead me to suspect the physical layer (cisco, cable, NT, etc). Since you do NOT have "isdn tei first" configured (although if you are in Germany that may be required), the physical layer should be up. The fact that you can attempt to make a voice call is interesting, too. Try adding the above command to the global config and see if that helps.

1st: the router is based in Italy, I am based in Germany, so I do not think this solves the problem
2. I have done a loopback call on the BRI interfaces, that is using 1 B-channel to call the other B-channel with "isdn call interface BRIx/y
3. I have checked and we could be experiencing several CISCO bugs like: CSCdu38445, CSCdu31091 and CSCuk24873.
Should we open a TAC case to confirm this??

Hello Mihai,
We have the same problem on 2610 running 12.1(12b), with configuring pool members. With rotary-groups it seems to run correctly.
Have you opened a case ? What are the results ?
Kind regards,
Bernard GUY

Hello,
we have had the same problems with IOS 12.1(11). Since we upgraded the Cisco's 2600 to 12.2(7) w have no further problems.

You're resurrecting a 10 yeard old thread.
Anyway, you can take "debug isdn Q.931" with "term mon", to check what happens.

If no debug output, you have controller or interface down, usually due to faulty circuit.

As indicated above already: Check controller and interface status.
