Hi All!
The problem is following:
till today we got PRI so:
(Router)---PRI---(Nortel PBX) ----PRI------(Telco)
we don't use Nortel PBX and don't want to pay a rent for it. So now we've connected:
(Router)----PRI------Telco
But now I get ISDN Se0/2/0:15 Q931: Ux_DLRelInd: DL_REL_IND received from L2 and have no communication
And L2 status changes periodically from TEI_ASSIGNED to AWAITING_ESTABLISHMENT
running config:
network-clock-participate wic 2
isdn switch-type primary-net5
controller E1 0/2/0

Have somebody hint how to solve the issue?

Hi
Try these commands:
network-clock-select e1 0/2/0
controller E1 0/2/0
clock source line
shut
interface Serial0/2/0:15
no isdn protocol-emulate network
shut
controller e1 0/2/0
no shut
interface Serial0/2/0:15
no shut
And see what you get... typically you don't emulate network when connecting to a telco.

Aaron

You should set clock source line, and ...
Oops, Aaron beated me to it.
08-25-2010 11:27 AM
made that changes, have the same problem

Check "show controllers E1", you may have a cabling issue.

Configure "network-clock-select 1 e1 0/2/0".
If still trouble, post config and outoput of "debug isdn q921" taken with "term mon".

Hi
What country are you based in?
Other things that may want changing are the crc4 setting, or possibly the net5 isdn type for another one if that was configured specifically for the Nortel...

Aaron,
Russia
I tried to change from no-crc to crc - controller didn't change to state up, isdn switch-type I did't change
08-25-2010 11:46 AM
Can you post your current config again?
08-26-2010 06:46 AM
L1 config shouldn't matter here if L1 is negotiating at all. If the system logs don't report L1 flapping when L2 goes down, then lincoding, clocking, and framing should be fine. As long as the controller runs clean with 'sh controller [t1|e1]' then that part is fine.
You mention you used to have this connected to a PBX, and are now going to the provider. That's your issue: yoiu are still configured as network side on the PRI, which means the gateway is going to expect to receive SABMEs. You need to be set to user side on this when interfacing with the provider:
interface Serial0/2/0:15
isdn protocol-emulate user
shut
no shut
If you still have issues after this, post a current:
sh ver
sh run
sh controller e1
sh isdn st
sh log | i %
Along with the output of 'debug isdn q921'.

Hi All!
I changed:
controller E1 0/2/0
isdn protocol-emulate user
shut
no shut
but it didn't help.
Telco support tells that "we must change mode from 'master' to 'slave' ", are the commands above make this?
Here are needed diagnostic data:

I can only assume that 'Master/slave' is referring to either network/user side (which we've discussed already) or in regards to clocking (which you are set to receive clock).
Can you run just 'debug isdn q921' instead of 'debug isdn q921 detail'? The latter doesn't decode what the outbound messages are. I want to make sure that the SABME messages are being sent to the provider. It looks like they are, and the T200 timer is the one that will pop, but I want to see the normal q921 debugs to be sure.
If 'debug isdn q921 shows us transmitting a SABME out the circuit, you need to get with your provider and have them tell you why they aren't responding with a UA.

Also, I see that the circuit has taken L1 errors. Issue 'clear counters' and make sure those counters stay at 0 during times where you know L1 isn't flapping.

Hi, Steve,
yes, SABME are sended to provider:
