Setting up Signaling Bits

	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
	DSn Operation

1Choose

PDH/DSn

on the TRANSMIT display.

2	Choose SIGNAL 2 Mb/s and PAYLOAD TYPE PCM30	or
	PCM30CRC on the MAIN SETTINGS display.

3If UNSTRUCTURED is chosen set the 2M CAS ABCD bits value on the MAIN SETTINGS display.

If STRUCTURED is chosen set the 2M CAS ABCD bits value on the

STRUCTURED SETTINGS display.
