Transition Networks SISPM1040-3xxx-L Web User Guide Delay Measurement 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 the transmitting and receiving timestamps of initiators and remotes. Frame Delay = (RxTimeb-TxTimeStampf)-(TxTimeStampb-RxTimeStampf) Interval : The interval between transmitting 1DM/DMM PDU in 10ms. The range is 10 to 65535. Last-N : The last N delays measurements used for average last N calculation. Min value is 10. Max value is 100 Unit : The time resolution (uS for microseconds or nS for nano-seconds). 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-tofar-end and far-end-to-near-end one-way delay are calculated. When DMM or 1DM is received, only far-end-tonear-end one-way delay is calculated. Counter Overflow Action : The action to counter when overflow happens (Keep or Reset). Delay Measurement State Tx : The accumulated transmit count - since last 'clear'. Rx : The accumulated receive count - since last 'clear'. 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'. 33763 Rev. G https://www.transition.com Page 354 of 496
