Problems with ISDN PRI and Cisco 2811 with WICs

[tsadi]

ive configured cisco 2811 routers, each with a WIC installed. Router "A" has a multiport WIC installed (2 ports) and router "B" has a single port WIC installed.

Both configurations are the same, except for the router with the dual-port WIC which have an extra controller and serial interface.

this is how it looks:

no ftp-server write-enable
isdn switch-type primary-net5

controller E1 0/0/0
channel-group 0 unframed

The ISDN line "should" be ready for use but i get "line down, protocol down" on both routers serial interface...

sadly im home and have no way of troubleshooting on this right now, but is there something obvious that i wrongly configured or missing. i pasted the relevant part of the config.

i did a little test before i left the site, i took an already working ISDN line cable from a NT box, and plugged it into my WIC port2 and immedialy the line and protocol went up/up, the same happent in the other end. i took and unplugged a random ISDN "cable" and plugged it into that router as well and same thing happent "line and protocol went up/up" in a 1sec.

im not strong on WAN and ISDN so when the custumer said that the new isdn line (PRI) was the same as the old, i simply copied the command "isdn switch-type primary-net5" on to the new router...

what im looking for is if i did something worng that causes the interfaces to stay down/down or maybe its the ISP who did not prepare the ISDN line as promised or maybe its a patch/cable problem.

ive found some good debugging/troubleshooting commands ill use on tuesday when i can enter the site, but i really hope this is not my fault. obvisouly.

Your ISDN isn't configured at all if that's the all the relevant parts of your config. All I see is a dual G703 E1 configuration.

What kind of ISDN module are you using? What's the Cisco part number?

Before i changed anything, this router had a single-port WIC installed and was connected to a NT box running ISDN PRI. Everything working fine and still is. I simply switched the WIC with a dual-port WIC module and added another controller/serial and connected nr 2 port on the module to new NT box, same kind (ISDN PRI). The old ISDN line is still working fine but i have link and protocol down/down on nr 2 WIC port.

So with this configuration, WIC 0 works fine and WIC 1 doesn’t. If i take the ISDN link from WIC 0 and put it in WIC 1, WIC it goes up/up. That is why i suspect there is something wrong with the new ISDN line/NT or some other cable issues between the routers and not the configuration.

But yes, there is no other configuration; however WIC 0 is working fine.

Isdn switch-type is set to primary-net5 and framing is set to unframed on the controllers.

Before i added the new WIC i checked the configuration to see what i needed to make the new WIC work. The “sh running” is here:

end

This is the conf as it was before i added the new WIC. I don’t see why I would need more ISDN configurations to make the second port work, something im missing?
