Delay Measurement
Setting Description
Enable
Delay Measurement based on transmitting 1DM/DMM PDU can be
enabled/disabled. Delay Measurement based on receiving and handling.
1DM/DMR PDU is always enabled.
Priority The priority to be inserted as PCP bits in TAG (if any).
Cast
Selection of 1DM/DMM PDU transmitted unicast or multicast. The unicast
MAC will be configured through 'Peer
MEP'.
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.
Ended
Single: Single-ended Delay Measurement implemented on DMM/DMR.
Dual:
Dual
-
ended
Delay Measurement implemented on 1DM.
Tx Mode
Standardize: Y.1731 standardize way to transmit 1DM/DMR.
Proprietary: Vitesse proprietary way with follow-up packets to transmit
1DM/DMR.
Calc
This is only used if the 'Ended' is configured to single-ended.
Round trip: The frame delay calculated by the transmitting and receiving
timestamps of initiators. Frame Delay = RxTimeb-TxTimeStampf
Flow: The frame delay calculated by 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.
Synchronized
Enable to use DMM/DMR packet to calculate dual-ended 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 delays are calculated. When DMM or 1DM is received, only far-end-

way delay is calculated.
Counter
Overflow Action
The action to counter when overflow happens.
