I have a 4331 router with PVDM4-128. I will be using this router for CME. I also have a NIM module with 1 port T1/E1. I will be terminating E1 PRI circuit in this card.
After reading this link
http://www.cisco.com/c/en/us/support/docs/routers/4000-series-integrated-services-routers/118792-config-isr-00.html
, I have the impression that I also need to have the PVDM installed in the NIM module in order to configure this port for voice circuit termination. Can somebody confirm whether the PVDM in the card is the must?
Thanks, Khanal
