[c-nsp] What to do about "Not enough DSP resources available" forpri-group?

[Oliver Boehmer (oboehmer)]

Peter,

if you want to do pure PRI data on the VWIC-2MFT-E1, please check the
URL
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124newft
/124limit/124x/124xc4/intserv.htm and use 12.4(9)T and later. However,
you still need DSPs (as mentioned in the above URL: "To support PRI data
calls, a VWIC-1MFT-E1 voice cards must have a packet voice data module
(PVDM)."
Guess for a pure data PRI, a NM-2CE1T1-PRI would have been a better
choice..
