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 56/64 kb/s but less
than DS1/2 Mb/s for example 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/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.
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 selected, an * marks the chosen timeslot. In the example
above Timeslots 3, 5, 9, 21, 22, 23 are selected for test.
4
Choose the PATTERN type and PRBS polarity.
5
Choose the B/G PATTERN.
