E1 Trunk with Panasonic box, will VWIC2-2MFT-T1/E1 work?

[vadoodetm]

Hi,

I have a 2811 which I inted to insert a VWIC2-2MFT-T1/E1 module on it and create trunks with a Panasonic TDA600 pbx. The extension card on Panasonic is PRI30.

I need the router to translate channels on this trunk to SIP. A SIP trunk will be made between Cisco and another IP PBX. So my router will only be used as a gateway.

I wonder if this module suites this scenario and whether it is a good chioce for this. I have also heard that I will need PVDM2 DSP modules. I am not sure what this DSP module will serve in this particular scenario. I also see references to network module cards (like NM-HDV, NM-HD-2VE, and NM-HDV2) on the datasheet page for the VWIC module. My 2811 does not have any extra network modules on it.

You should be able to use that card. The DSPs would be used to convert from/to TDM and VoIP.

Thank you roger,

I still cannot tell if DSP is needed for my scenario.

You will need DSPs. The E1/T1 is a TDM card and the IP link would be VoIP.
