tsm_stat_req_vp_delay
Syntax:
tsm_stat_req_vp_delay chNum
Return the DSP Voice Playout Unit (VPU) statistics for the call on the
channel specified. This command applies only to the VGMCs. The variable
DimDspStat = must be assigned a value of 1 for this command to produce
output. The VPU operates on segments of 10 milliseconds of voice. The
following data prints:
•
number of lost segments during the call based on the missing
sequence number
•
number of segments replayed due to the lost packets
•
number of idle (noise) segments being played out due to either lost
packets or voice playout FIFO buffer underrun
• number of voice segments dropped due to the voice playout FIFO
buffer over-run
• total number of segments submitted by packetization unit for playout
•
average frame jitter seen from network (in Telogy 7.01 output only).
You can repeat the query for the duration of the call. The counts are reset
at the beginning of the next call.
The following table describes the command parameters.
