Setting Transmit N X 64 kb/s
(N X 56 kb/s) Structured Payload/Test
Signal
Description Wideband services such as high speed data links and LAN
interconnection require a bandwidth greater than 64 kb/s but less than 2
Mb/s for example 128 kb/s or 384 kb/s. These wideband signals are sent
in a 2 Mb/s frame by sharing the signal between multiple timeslots.
N X 64kb/s structured payload allows a test pattern to be inserted across
a number of Timeslots even if the chosen Timeslots are non-contiguous.
Structured payloads are only available if Option UKJ, Structured PDH,
or Option 110, DS1, DS3, E1, E3 structured PDH is fitted.
Option
Differences
Option 110 provides a choice of Nx64 kb/s or Nx56 kb/s Test Signals with
a DS1 payload. The Nx56 kb/s selection is similar to Nx64 kb/s except
that the last bit in each timeslot is set to 1.
HOW TO: 1 Choose the required Test Signal rate.
2 Choose the Framing pattern of the 2M or DS1 (Option 110) PAYLOAD.
3 Choose the test timeslots within the structured payload using
and softkeys. As each
timeslot is chosen a * marks the chosen timeslot. In the example
