Structured Payload/Test Signal
Description Wideband services such as high speed data links and LAN
interconnection require a bandwidth greater than 56/64 kb/s but less
than DS1/2 Mb/s e.g. 112 kb/s or 336 kb/s. These wideband signals are
sent in a DS1/2 Mb/s frame by sharing the signal between multiple
timeslots.
N x 64kb/s and N x 56 kb/s structured payload/test signal allows the test
Timeslots to be chosen for error measurement even when the Timeslots
are non contiguous.
HOW TO: 1 Choose the required Test Signal rate.
2 Choose the Framing pattern of the 2M or DS1 PAYLOAD.
3 Choose the test timeslots within the structured payload using
and softkeys. As each
timeslot is chosen an * marks the chosen timeslot. In the example
above Timeslots 3, 5, 9, 21, 22, 23 are chosen for test.
4 Choose the PATTERN type and PRBS polarity.
