check_snmp currently does not support operations on returned values.

workarounds:

1. take a look at contrib/check_maxchannels.pl  
(monitor ISDN lines and modems on Ascend MAX 200/4000/6000/TNT)


2. if you know the number of modems (should be relatively fixed per 
device :) you can include that in the "-u" label

eg: check_snmp -H host -C comm -o oid_of_unused -u " unused (of 48 modems)"


3. rework check_ifoperstatus to do the operations you are interested in..


of 1 maybe what you are looking for  ;)
