Router 1751 and PVDM-256K-4

[gclemente]

Hi

i have a router 1751 equipped only with a Vic-2bri-NT/TE; i will use only one interface (so only two voice channels, one BRI); have i to use one PVDM-256k-4 or two PVDM-256k-4 (or one PVDM-256k-8) if i use only two voice channels and not all four voice channels that are available?

thank you for your support

It seems that you do not need an extra PVDM, according to the following url : http://www.cisco.com/univercd/cc/td/doc/pcat/1750.htm, you must support 2 voice channels with only one PVDM, but i have never tried that.

Best Regards!
