Re: Cisco 2821 - E1 PRI and PVDM issue

First of all you should upgrade you IOS as you're still running the initial version of 12.4-9T, likely buggy.

Then, you should have clock source line and network-clock-participate and -select.

Also note, the PVDM2-64 for voice, will not work with the channelized PRI card for data. It works exclusively with cards that have V in the part number, likve VWIC.

Finally, please do not put time pressure for answers, as this is a free forum, not a paid for service.
