CBIT

CBIT:

The CBIT bit enables the C-bit parity application. When CBIT is a logic 1, C-

bit parity is enabled, and the associated functions are inserted in the C-bit

positions of the incoming DS3 stream. When CBIT is a logic 0, the M23

application is selected, and the C-bits are passed transparently through the

DS3 TRAN.

SBOW:

The SBOW bit selects whether to insert the bit from the TOH input into the

stuff opportunity bit or into the F4 bit. When SBOW is a logic 1, the bit from

the TOH input is inserted into the stuff opportunity bit. When SBOW is a logic

0, the bit from the TOH input is inserted into the F4 bit.

FERF:

The FERF bit enables transmission of far end receive failure in the outgoing

DS3 stream. When FERF is a logic 1, the X1 and X2 overhead bit positions

in the DS3 stream are set to logic 0. When FERF is a logic 0, the X1 and X2

overhead bit positions in the DS3 stream are set to logic 1.

AIS, IDL:

The AIS and IDL bits enable the transmission of the alarm indication signal

and the idle signal. When AIS is a logic 1, the transmit DS3 payload (on the

TDAT/TPOS and TNEG outputs) is overwritten with the pattern 1010... When

IDL is a logic 1, the transmit DS3 payload is overwritten with the pattern

1100...
