Rx Error The accumulated receive error count - since last 'clear'. This is counting if the frame delay is
larger than 1 second or if far end residence time is larger than the round trip time.
Av Delay Tot The average total delay - since last 'clear'.
Av Delay last N The average delay of the last n packets - since last 'clear'.
Delay Min. The minimum delay - since last 'clear'.
Delay Max. The maximum delay - since last 'clear'.
Av Delay-Var Tot The average total delay variation - since last 'clear'.
Av Delay-Var last N The average delay variation of the last n packets - since last 'clear'.
Delay-Var Min. The minimum delay variation - since last 'clear'.
Delay-Var Max. The maximum delay variation - since last 'clear'.
Overflow The number of counter overflow - since last 'clear'.
Clear Set of this check and save will clear the accumulated counters.
Far-end-to-near-end
one-way delay
The one-way delay is from remote devices to the local devices. Here are the conditions
to calculate this delay. 1. 1DM received. 2. DMM received with D2forD1 enabled. 3. DMR
received with D2forD1 enabled.
Near-end-to-far-end
one-way delay
The one-way delay is from the local devices to remote devices. The only case to calculate
this delay is below. DMR received with D2forD1 enabled.
Delay Measurement Bins
A Measurement Bin is a counter that stores the number of delay measurements falling within a specified range,
during a Measurement Interval.
Measurement Bins for
FD
Configurable number of Frame Delay Measurement Bins per Measurement Interval.
The minimum number of FD Measurement Bins per Measurement Interval supported is 2.
The maximum number of FD Measurement Bins per Measurement Interval supported is 10.
The default number of FD Measurement Bins per Measurement Interval supported is 3.
Measurement Bins for
IFDV
Configurable number of Inter-Frame Delay Variation Measurement Bins per Measurement
Interval.
The minimum number of FD Measurement Bins per Measurement Interval supported is 2.
The maximum number of FD Measurement Bins per Measurement Interval supported is 10.
The default number of FD Measurement Bins per Measurement Interval supported is 2.
Measurement Threshold Configurable the Measurement Threshold for each Measurement Bin.
The unit for a measurement threshold is in microseconds (us).
The default configured measurement threshold for a Measurement Bin is an increment of
5000 us.
Delay Measurement Bins for FD
A Measurement Bin is a counter that stores the number of delay measurements falling within a specified range,
during a Measurement Interval.
If the measurement threshold is 5000 us and the total number of Measurement Bins is four, we can give an example
as follows.
Bin Threshold Range
bin0 0 us 0 us <= measurement < 5,000 us
bin1 5,000 us 5,000 us <= measurement < 10,000 us
bin2 10,000 us 10,000 us <= measurement < 15,000 us
bin3 15,000 us 15,000 us <= measurement < infinite us
