Setting up Signaling Bits
Description
When transmitting 2.048 Mb/s signals with timeslot-16 CAS (PCM30 or
PCM30CRC) multiframing the state of A,B,C,D signaling bits can be set.
The signaling bits of all timeslots are set to the user-defined 4 bit value.
When transmitting a DS1 framed, structured signal the values of the
A,B signaling bits for D4 and SLC-96 payloads, and A,B,C,D signaling
bits for ESF payloads can be defined.
HOW TO
Transmit a 2 Mb/s signal with user-defined signaling bits
