CHAPTER 4
WEB OPERATION & CONFIGURATION
Peer MEP:
This is only used if the 'Cast' is configured to Uni. The 1DM/DMR unicast MAC will be taken from the
'Unicast Peer MAC' configuration of this peer.
Way:
One-Way or Two-Way Delay Measurement implemented on 1DM or DMM/DMR, respectively.
Tx Mode:
Standardize:
Y.1731 standardize way to transmit 1DM/DMR.
Proprietary:
The proprietary way with follow-up packets to transmit 1DM/DMR.
Calc:
This is only used if the 'Way' is configured to Two-way.
Round trip:
The frame delay calculated by the transmitting and receiving timestamps of initiators. Frame Delay =
RxTimeb-TxTimeStampf
Flow:
The frame delay calculated by the transmitting and receiving timestamps of initiators and remotes. Frame
Delay = (RxTimeb-TxTimeStampf)-(TxTimeStampb-RxTimeStampf)
Gap:
The gap between transmitting 1DM/DMM PDU in 10ms. The range is 10 to 65535.
Count:
The number of last records to calculate. The range is 10 to 2000.
Unit:
The time resolution.
D2forD1:
Enable to use DMM/DMR packet to calculate one-way DM. If the option is enabled, the following action will
be taken. When DMR is received, two-way delay (roundtrip or flow) and both near-end-to-far-end and far-end-to-
near-end one-way delay are calculated. When DMM or 1DM is received, only far-end-to-near-end one-way delay is
calculated.
Counter Overflow Action:
The action to counter when overflow happens. The options available include “keep” and
“reset”.
Delay Measurement State
Tx:
The accumulated transmit count - since last 'clear'.
Rx:
The accumulated receive count - since last 'clear'.
Rx Timeout:
The accumulated receive timeout count for two-way only - since last 'clear'.
Rx Error:
The accumulated receive error count - since last 'clear'. The frame delay is larger than 1 second (timeout).
Average Delay Total:
The average delay - since last 'clear'. The unit is microsecond.
Average Delay last N:
The average delay of the last n packets - since last 'clear'. The unit is microsecond.
