Subject: [ipcdn] IETF NCS Sig MIB draft 6 -> Issue for pktcSigDevToneWholeToneRepe atCount/pktcSigDevToneSteady when duration is shorter than TO

Satish,
 
Thanks for raising this issue. The intent of the pktcSigDevToneWholeToneRepeatCount and pktcSigDevToneSteady was to support telco industry standards. If a tone definition using repeat count objects results in a tone sequence that is shorter than the TO time, the repeat count takes significance. I checked the NCS spec on this issue and I don't see a clear indication of expected behaviour when a tone duration is shorter than an associated TO.
 
Do you have text you would like to propose as a solution for the description of these objects?
 
Comments?

>The MIbs specify the case where longer duration is set. However they do not specifically say what to do in the case >where setting the pktcSigDevToneWholeToneRepeatCount results in a tone duration which is shorter than the tone >duration which is specified through the timeout (TO)???    
 
>What is the expected duration behavior in this case?? Does the MTA has to observe the specified number of repeat counts?? or does it stick to the value in timeout(TO) MIB?  Please throw some light on expected behavior.

           "This is the repeat count, which signifies how many times 
            to repeat the entire on-off sequence. Setting this object 
            may result in a tone duration longer than the overall 
            signal duration specified by the time out (TO) object for a 
            particular signal. In this case, the tone duration defined 
            by the TO object for a particular signal always represents 
            the overall signal duration for a tone."
