Simulate ISDN over BRI Port!

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
