Hi,

I have been searching through the newsgroup for similar and relevant
isdn bri layer 2 issues, and did come up with some hits. I just
wanted to confirm some things as I'm not getting much joy from my
telco or isp (always great when you have two different providers for a
service, wasnt my choice!)

We moved premises, and had the isdn service moved with us. I've had
a technician from the telco come out and "confirm" that the service
exists (ran Layer 1,2,3 tests with their handset utility).

I've got a 2621XM with a WIC-1B-S/T that I wish to use (isdn will
eventually be the backup link, but im not worried about that aspect
yet as I'd LOVE isdn to work first). I have thrown what was known as
the working configuration onto it from a non dead 1003 router.

sh isdn status displays the following:

Global ISDN Switchtype = basic-net3
ISDN BRI0 interface
dsl 0, interface ISDN Switchtype = basic-net3
Layer 1 Status:
ACTIVE
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

looking at the log with debug isdn error, debug isdn q931 and debug
isdn isdn q921 enabled shows this:

000136: *Mar 1 00:17:29.011 UTC: ISDN BR0/0 **ERROR**:

sh dialer displays:

Dial String Successes Failures Last DNIS Last status

0294681000 0 7 00:02:34 failed
Default

manually dialing using isdn test call interface bri0/0 0294681000 and
logging dialer shows:

000126: *Mar 1 00:13:32.659 UTC: BR0/0 DDR: Attempting to dial
0294681000
000127: *Mar 1 00:13:38.959 UTC: BRI0/0: wait for isdn carrier
timeout, call id=0x8003


Is this a telco problem (service provision), or an isp related issue?

TIA

Greg

[debug cutted]

My guess would be that you have set the wrong switch type. If you
connect ISDN telephone can you use the line?

ISDN telephone works on the line - the problem was that the telco had
set the line to point-to-point rather than point-to-multipoint.
Router can connect now, just sorting out some routing issues now.

Thanks for your response.

Dear Team,

We have resolved the service provider issues,Voice call & data transection is perfctly ok.But we have getting Layer 1 deactivated.NT-1 side is perfectly ok.

Kindly give the suggestion for this.
