Did anybody ever configure a Madge/Teleos/Initia AccessSwitch 20?

[ericw12]

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 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.. but I am not sure... I would appreciate any help! The following is some configuration and debug information.

You don't seem to have defined any ppp authentication between the 2 routers? Is this your attention? If not, configure 'ppp authentication chap' on both BRI interfaces and setup a username with the same shared password on both routers.

Hi guys!

My bad. It is working now. It is the SPID I did't configure in the switch for simplicity, and it must have one for 5ess

Thanks!
