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 for example 128 kb/s or
384 kb/s. These wideband signals are sent in a DS1/2 Mb/s frame by sharing the
signal across multiple timeslots.
N x 64kb/s/N x 56 kb/s structured payload allows a test pattern to be inserted across
a number of timeslots even if the chosen timeslots are non-contiguous.
1 Choose the required Test Signal rate.
HOW TO:
2 Choose the Framing pattern of the 2M or DS1 PAYLOAD.
3 Choose the test timeslots within the structured payload using
* marks the chosen timeslot. In the example above Timeslots 3, 5, 9, 25, 26, 27
are selected for test.
4 Choose the PATTERN type and PRBS polarity.
5 Choose the B/G PATTERN.
6 The B/G PATTERN in the non-test 64 kb/s timeslots is fixed as NUMBERED,
that is, each timeslot contains a unique identification number.
