Hello Richard,

I've found the following link


http://www.cisco.com/en/US/docs/ios/12_3/vvf_c/cisco_ios_isdn_voice_configuration_guide/isdn031.html


It says:

The EVM-HD-8FXS/DID baseboard network module provides eight Foreign Exchange Station (FXS) or direct inward dialing (DID) ports. This network module accesses digital signal processor (DSP) modules on the motherboard, instead of using onboard DSPs. You can increase the port density by plugging in up to two optional expansion modules in any combination:


•EM-HDA-8FXS-8-port FXS voice/fax expansion module


•EM-HDA-3FXS/4FXO-3-port FXS and 4-port FXO voice/fax expansion module


•EM-HDA-6FXO-6-port FXO voice/fax expansion module


•EM-4BRI-NT/TE-4-port ISDN BRI expansion module


If your router has this network module EVM-HD-8FXS/DID verify if you have installed the right expansion module EM-4BRI-NT/TE.


and also:

Patch Panel Installation


For the BRI interface port, you must install an appropriate patch panel. Patch panels are generally available from multiple cable and network adapter vendors:




Hope to help

Giuseppe

I have a vic2-4fxo installed, and was reading that I could use this as a BRI interface.

OK, I guess misunderstood what I had read. Would it be the same situation with the FXS interface?
