Have you set the controller on it, probably isn't providing clocking properly? You might want to find out what you need to set everything to from your provider.

controller T1 5/0
framing esf
linecode b8zs
channel-group 0
timeslots 1-24
 
Ignore my previous example, here try this as an example of what you need to setup for your controller.

controller T1 0/0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24 speed 64
 
Made a mistake, should be 1-23
My fault on that there....

channel-group 0 timeslots 1-23 speed 64


Would also need to set the D channel

serial 0/0:n

n= 1-23 suggest 23 This is so you can set the D channel for the ISDN PRI. So in all truth the command would look like this:

serial 0/0:23

 
***tschouten:

Why do you have clock source internal?

I have the clock source as line

***gunthnp:

the no fair-queue - I believe that is the default - should I remove it?
 
Is your service provider (providing clocking) or not? This is why I said you should contact them and see what they have set up. Most likely they arenot providing your clocking so you need to setup clock source internal.
 
This problem doesn't have anything to do with queueing, so the no fair-queue could stay or go.. It appears to be an integrated csu/dsu, so there shouldn't be any controller t1 lines in there (it's all handled by service-module t1 under the interface config mode). Since the physical layer isn't up, are you sure it's plugged in properly and your service provider isn't looping the smartjack (I've had this happen a few times)? Can you do a show service-module ser0/0 and paste it in here?
 
I won't be able to get that today...will do that on Wed...thanks for your insight. Will reply asap.
 
right but no fair come up if the line is down when you set it up you need that off but the porblem is phy is the t1 on I have had the phone company more then once removeed a line when they should not have

gunthnp
 
Well, my suggestion is that there's a wiring problem. Is this an extended demarc? (i.e. is there just a little 2-inch square rj-45 jack that you connect into (extended demarc), or do you plug directly into the NIU--a box containing cards with lights on them (non-extended demarc)?) When you plug your router into the T1, what lights come on? If the CD light does not come on, then your router is not getting an electrical signal from the telco.

When you call them, and everything's plugged in, have them try to loop your DSU and see what they say.
 
****Response to the wiring:****
Question: When you plug your router into the T1, what lights come on? If the CD light does not come on, then your router is not getting an electrical signal from the telco.

Answer: The T1 at the Secaucus NJ location is plugged directly into the Router port and the Data Center Port.
The lights do come on.

Hmmmm... well, let's look at the service modules: the one in Secaucus reports loss of framing while the other shows line code violations and line errors as well as loss of framing. This could indicate problems at the Gloucester router. Just to clarify: on the WIC on the router, the CD light is green, and the AL light is off?

Also, I'd try removing the &quot;service-module t1 remote-alarm-enable&quot; command from either end, it's not really necessairy and might cause problems.

Another thing you can try is a &quot;debug service-module&quot;, &quot;debug ppp error&quot;, &quot;debug serial interface&quot; or &quot;debug interface serial0/0&quot; and see if it dumps anything interesting. Note that you may need to use the &quot;terminal monitor&quot; command if you're not directly connected at the console.

Is this a private-line T1? If so, if you've got control of the routers on either end, try setting the encap to HDLC rather than PPP on both, see if that makes a difference.

Another thing I noticed from the outputs you pasted, the ethernet addresses of both routers are the same, which won't cause a problem with your T1, but will give you problems routing since your subnet addresses aren't unique.

Hope this helps
