Cisco 3640 / Wic T1 Problem

[Podolak]

Hello Everyone,

The problem that I seem to be experiencing is that with my Cisco 3640 (IOS 12.3) I can't seem to bring up my Wic T1 interfaces. I can bring up the fast ethernet but not that. I've also tested the Wic 1T's in a 2610 router with my T1 Connection and all of those variables seem to work. Any ideas?

Thanks,

-Mike

what do you mean you can't bring them up?

Do you get up/up or up/down? what protocol is it running - HDLC, frame, PPP, etc?

Is this for Lab or Production?

Are you connecting to a real T1 (or something that looks like a T1), or with a crossover cable (1&2 --> 4&5) to another router?

I'm asking because if you are connecting back-to-back, one of the routers must be set to be a DCE and provide clock (intf-type DCE, clock rate xxxx).

If you are attached to a real T1, but it's fractional (<1.544), you need to go to the serial interface and issue one or more "Service-Module" commands to define the channel group.

Also if it's a real T1, verify Framing (usually ESF) and line code (usually B8ZS).

Is the interface Up/Down or Down / Down?
Are you getting clock?

Post the interface dump for that serial if you can.

Gotta know

I will work on the interface dump.

The interface is connected to a real T1. And what I should have said was that I can't get the interface to even be detected by the router. Those these interfaces are detected ok in another router. I've updated the IOS as well.

it will show up as a serial interface like serial 2/1

Indeed it should but it does not

well then the only thing I could think of is IOS version (and IOS train) for that hardware,

 

[Podolak]

have thought the same. Sadly enough I've tried many different versions. Including 12.3(10) as well as Enterprise.

If these cards didn't work in a 2610 I'd be thinking dead cards but as that isn't the case I'm at a loss for what it could be...

call cisco.

can you do "show controller serial 1/1" or whatever the module/slot is?

 

[Podolak]

I can try that command out. I'll post back here with the responce.

Try "show controller t1 1/1" or whatever the module/slot is

 

[ScottMac]

What kind of netmod are you installing the WIC into?

The netmod is the larger module that fits into the slot/bay.

It should be something like 1E2W (which would be a 1 Ethernet, 2 WIC netmod).

You should also try pulling the netmod from the 2600 and trying it as a whole unit (netmod + WIC) in the 3600. You may have a flakey netmod, or one that is incompatible with with your WIC.

great point Scott!
