configuring vwic 1mft1 for voice
I've been trying to configure the vwic 1mft1 from the 2811 (cme) to 1760v(pstn). Been running into some roadblocks last night. I figured this morning at work I get 2 vwic 1mft1 from 2 2811's and connect them so I can get the command working.
These are the cmds I placed on both:
network-clock-participate wic 0
isdn switch-type primary-ni
controller T1 0/0/0
framing esf
linecode b8zs
pri-group timeslots 1-24
On one of the routers all 24 serial interfaces came up on the other I get this error:
% Not enough DSP resources available to configure pri-group on controller T1 0/0/0
% The remaining dsp resources are enough for 0 time slots.
% For current codec complexity, 2 extra dsp(s) are required to create this voice port.
Router(config-controller)#
I figure that I would get this error due to not having pvdms. Both don't have anything onboard. Odd part on the one that worked its running
c2800nm-advsecurityk9-mz.124-15.T3.bin
On the one that gives the me the error has this one:
c2800nm-advipservicesk9-mz.124-18.bin
My question is why would the serial interfaces come up on the one with the advsec ios without any pvdms? I even tftp'd the advip on the one with the advsec and sure enough I got the same error.

You are correct, the reason is that you don't have enough PVDMS to create a PRI. The serial interfaces do not require any DSP resources, that is what I love about those cards is that you can use them for both DATA & Voice. As for the IOS, I can't say for sure what the deal is, maybe the advanced IP Services is lacking in voice features, check the Feature navigator. Neither image works though right? I think you need at least two PVDM2 chips to make this work.
