ISDN problem with a Madge/Teleos/Initia AccessSwitch 20

[ericwang12]

I am trying to configure it as the ISDN switch, and route calls for two Cisco routers, but I couldn't get it working. I am hoping someone here has been worked with one of the AccessSwitch...

I can see the Layer 1 and 2 are up, but the layer 3 won't work properly. One weird thing is both of the router got the same TEI, they are all 64. I am thinking I might screwed somewhere like dial-plan or something in Madge, but I am not sure... I would appreciate any help! The following is some configuration and debug information.

############

Router R5, connect to BRI Port 2

I am a little confused where your comment is that the router is on Bri port 2 but the config says BRI0:

Router R5, connect to BRI Port 2

interface BRI0

perhaps you can clarify that?

I note that your config does not include any authentication. I assume that you have not done that yet in the interest of simplifying the config to get it to work. But you probably want authentication once you get this issue resolved. (and I do not believe that your present problem has anything to do with authentication.)

The show isdn status indicates that the router and switch seem to be talking normally. But the debug q931 shows a serious problem:

Cause i = 0x82B4 - Service operation violated.....

I am not sure what causes that but suspect it is something in your setup of the switch. Perhaps you can tell us a bit about the switch.

Thanks Rick!

My bad, I got this thing working now. It is the 5ess implementatioin in this thing demands at least one SPID is configured properly. I did't configure the SPID in the switch side for simplicity initially.

Again, thanks for helpping, appreciated!

I am glad that you got it working.

Thanks for posting back to the forum and indicating what the solution was. It makes the forum more useful when we see descriptions of problems and then see what resolved the problem.
