It seems that your ISDN is using Backup interface command.
Check on your serial interface config, you should be able to see
some command as shown: "backup delay 30 300
backup interface BRI 0/0
Just remove the command from the interface, and your BRI 0/0 will become up,
up

Subject: ISDN interface problem
Hi there colleagues,
I have a problem with my ISDN interface on a Cisco 2610 router. I just had a
Telekom engineer at the site verify that the line is ok to the interface,
but he cannot see any lights burning on the intreface (B1 and B2 LEDs). When
I do a sh isdn status, I get the following:
Ener_Erkath#sh isdn status
Global ISDN Switchtype = basic-net3
ISDN BRI0/0 interface
dsl 0, interface ISDN Switchtype = basic-1tr6
Layer 1 Status:
DEACTIVATED
Layer 2 Status:
Layer 2 NOT Activated
Layer 3 Status:
0 Active Layer 3 Call(s)
Activated dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0
When I change the ISDN switchtype to basic-net3, it doesn't change the
status of the ISDN.
Here is the output from the sh int bri0/0:
Ener_Erkath#sh int bri0/0
BRI0/0 is standby mode, line protocol is down
Hardware is PQUICC BRI
Internet address is 10.90.1.70/30
MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec, rely 255/255, load 1/255
Encapsulation PPP, loopback not set
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0 (size/max/drops); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/0/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
21036936 packets output, 2224160372 bytes, 0 underruns
0 output errors, 0 collisions, 3 interface resets
0 output buffer failures, 0 output buffers swapped out
140 carrier transitions
Does anybody know if this could just mean that the interface is not
functioning at all ? What do the carrier transitions mean ? And what does
'standby mode' mean ?
I am also not able to bounce the interface (shutdown/no shutdown doesn't
change the status on the interface, it remains in standby mode).
Thanks for your help in advance !
Regards,
Georg
