Maximum PVDM on Cisco 2921

[b.paik]

Hi All,

First of all, Thank you in Advance for looking at my question.

My Query is: What is the maximum PVDM that can be installed in Cisco 2921. Cisco 2921 has 3 PVDM slots and until today i thought they could be filled with PVDM3-256 if required but someone in distribution threw me off by saying 256 is the maximum!. i would like to confirm that PVDM3-256 can be installed in each slots, which allows totaling of 768 (very expensive, i know).

I have a high demand to use PVDM's as i am doing RTP-SRTP and SIP-SIPTLS and also doing secure conferencing on the router.

Thanks again,

Regard,

B

Yes you can install 3 x PVDM3-256.

Use DSP Calculator for Sizing.
