RTD/RTT (CPRI/OBSAI Framed L2)
Round Trip Time (OBSAI)
Indicates the time required for a bit to travel from one point to another.
RTT indicates the round trip time measurement from the Base Station
going through the Remote Radio Head (including Delay 1,2) and
back to the Base Station. The RTT appearing on the diagram
corresponds to the average value.
Propagation Delay indicates the propagation delay measured from
the Base Station to the Remote Radio Head (RRH) or vice-versa
assuming that the cabling in both directions are in the same cable
bundle. The Propagation Delay appearing on the diagram
corresponds to the average value.
Last indicates the result of the last time/delay measurement.
Minimum indicates the minimum time/delay recorded.
Maximum indicates the maximum time/delay recorded.
Average indicates the average time/delay value.
Unit measurement selections are µs (default) and ns.
Delay 1,2 reports the internal delay introduced by the electronic
components in the Remote Radio Head (RRH).
