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.

2Choose the Framing pattern of the 2M or DS1 PAYLOAD.

3Choose the test timeslots within the structured payload using

DESELECT ALL DESELECT SELECT 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.

4Choose the PATTERN type and PRBS polarity.
