Found the following from some forum...
any one have any idea on whether the below works? i mean without buying expensive isdn simulator ?
Previously it was not possible, but now it is !!! (if you have the correct IOS).
- Here is a sample configuration with Voice-BRI interface BRI1/0 description So-Bus to R1 - We are NetworkSide no ip address isdn switch-type basic-qsig isdn protocol-emulate network isdn layer1-emulate network isdn incoming-voice voice !
- For Data-BRI the config should be similar.
- For PRI (T1 or E1) , you'll have to define the layer clocking on the T1/E1 controller with "clock-source line internal)
You need to build special cables by crossing TX and RX pairs please go to the CCO or the pin-out description for T1/E1 and BRI (you cannot user an Ethernet cross-over cable !)
Have fun, the feature is great and avoid you to buy a PBX
