RTD/RTT (CPRI/OBSAI Framed L2)
Round Trip Delay (CPRI)
Indicates the time required for a bit to travel from one point to another.
Delay T14
indicates the round trip delay measurement from the Base
Station going through the Remote Radio Head (including
Toffset
) and
back to the Base Station. The
Delay T14
appearing on the diagram
corresponds to the average value.
Cable Delay
indicates the cable delay measured from the Base Station
to the Remote Radio Head (RRH) or vice-versa assuming that the
cabling in both directions are the same. The
Cable Delay
appearing on
the diagram corresponds to the average value.
Last
indicates the result of the last delay measurement.
Minimum
indicates the minimum delay recorded.
Maximum
indicates the maximum delay recorded.
Average
indicates the average delay value.
Unit
measurement selections are
μ
s
(default) and
ns
.
Toffset
allows the configuration of the internal delay introduced by the
electronic components in the Radio Equipment (RE): 0
μ
s (default) to
66.67
μ
s.
Note:
A warning icon appears next to the
Toffset
value when this value is larger
than the
Delay T14
value measured indicating that the
Toffset
configured
value maybe invalid thus corrupting the
Cable Delay
values reported.
