I've a Cisco 2621xm with, NM-2V, VIC 2B-NT/TE and 2 VIC-FXS.
When booting I get the message that the router doesn't have enough DSPS (Cannot support all voice channels on VICs). Thus I have only 2 voice channels (1/0/0 and 1/0/1) instead of 4 (+1/1/0 and 1/1/1). What is the problem?
You have six voice channels in the NM-2V: four channels in the VIC 2B-NT/TE and two channels in the FXS. NM-2V only supports four channels. It is likely that the 2600, in this moment, only sees the four channels in the VIC 2B-NT/TE.
I think that you would have the VIC 2B-NT/TE in one router and the 2 VIC-FXS in other ´router.
If you put the BRI module in the 1st slot it will use all the DSP resource. If you put the FXS port in the 1st slot it will work, leaving enough DSPs for 1 of the BRI ports to work in the 2nd slot. OK if you only need 1 BRI port.

If you want to download them you have to prefix "file get " and you can add one of the options (re...
