Group Members
³
Member indicates the timeslot number.
³
SQ (Sequence Indicator): Indicates the received member sequence
indicator.
³
Differential Delay: Indicates the differential delay value for each
member. The graphical representation shows the differential positive
and negative delays for each member. A delay value bar at the left side
of the vertical line represents a negative delay while the one on the
right side represents a positive delay. A member having a negative
delay compare to another one having a positive delay indicates that
this member is faster than the other one. The differential delay is
measured compared to the reference member.
Note: The differential delay measurement accuracy is ±125 μs for HOP and
±500 μs for LOP except for TU-3, which has an accuracy of ±125 μs.
