Hello all,

I would like to install My E1 ,on cisco ISR 4321 , but it not work , it give me the message error:

The motherboard PVDMs are supported on all Cisco 4000 Series ISRs except the ISR 4461. They can be plugged directly into the single slot on the router motherboard or into the Network Interface Module (NIM) that supports T1/E1 ports. A PVDM4 module plugged into the motherboard delivers IP-based voice services such as conferencing, media optimization, and transcoding only.

A PVDM4 module plugged into the T1/E1 NIM would be used for voice T1/E1 connectivity. Any excess channels can be reused toward other IP-based services supported on the motherboard slot. Enhanced DSP architecture accommodates a new packet-processing engine optimized for rich-media voice applications, while concurrently supporting the TDM-IP voice framework.

You need PVDM on NIM card. couple of time, we received router with PVDM installed on motherboard even we ordered it on NIM. if you don't need the PVDM on motherboard for IP based services  you can remove it from mother board and install it on NIM card(recommended by professional people). 

how to install the PVDM is mentioned in the below document.
