Re: Pulse Metering

Hi!
 
Your definition for pri is taken from the Enable Metering signal. My question was about the Metering Pulse Burst signal. It may well be that the definition of the pri in the Metering Pulse Burst signal is wrong.
 
Regards,
Bruno

Hi 
    In H.248.26: 
    

Pulse Repetition Interval 

ParameterID:        pri (0x0002) 

Type:                        Integer 

        Possible values:        Any positive integer 
        This parameter specifies the interval over which the pulses specified in the pulse count should be issued, 

6.5        Procedures 
        If the pulse count is greater than 0, then the MG shall determine the appropriate interval between pulses by dividing the pulse repetition interval value by the pulse count. In the event that the interval determined is not integral, then it is the responsibility of the MG to adjust the individual intervals to avoid long-term rounding errors. 

     So I think the pri parameter means total interval for all pulses specified in mpb signal.

I have a question about the Metering Pulse Burst signal defined in H.248.26 (01/2005). This signal has two parameters: Burst Pulse Count & Pulse Repetion Interval. The Burst Pulse Count parameter specifies the number of metering pulses to be applied as a burst on the line. The description of this parameter says that "The type, duration and pulse repetition interval for the metering pulses comprising the burst are provisioned in the MG". 

Considering that the pulse repetition interval is provisioned in the MG, I don't understand the reason why this signal has a "Pulse Repetition Interval" parameter. Furthermore the default value for the "Pulse Repetition Interval" parameter is "1" rather than "provisioned". 

Can someone shade some light on this? 

Thanks 
Bruno 

6.3.2.1.1 Burst Pulse Count 
Parameter name: Burst Pulse Count 
Parameter ID: bpc (0x0001) 
Description: This parameter specifies the number of metering pulses to be applied as a burst 
on the line. The type, duration and pulse repetition interval for the metering 
pulses comprising the burst are provisioned in the MG. 
Type: Integer 
Optional: Yes 
Possible values: 1 or more pulses 
Default: 1 
6.3.2.1.2 Pulse Repetition Interval 
Parameter name: Pulse Repetition Interval 
Parameter ID: pri (0x0002) 
Description: Interval from the leading edge of a metering pulse to the leading edge of the 
next metering pulse. 
Type: Integer 
Optional: Yes 
Possible values: 1 or more milliseconds 
Default: 1 _______________________________________________
