NAME AND DESCRIPTION

RSRE

CCR4.7

Receive Side Signaling Reinsertion Enable. See Section 7.2 for

details.

0 = do not re-insert signaling bits into the data stream presented at

the RSER pin

1 = re-insert the signaling bits into data stream presented at the

RSER pin

RPCSI

CCR4.6

Receive Per-Channel Signaling Insert. See Section 7.2 for more

details.

0 = do not use RCHBLK to determine which channels should have

signaling re-inserted

1 = use RCHBLK to determine which channels should have

signaling re-inserted

RFSA1

CCR4.5

Receive Force Signaling All 1s. See Section 7.2 for more details.

0 = do not force extracted robbed-bit signaling bit positions to a 1

1 = force extracted robbed-bit signaling bit positions to a 1

RFE

CCR4.4

Receive Freeze Enable. See Section 7.2 for details.

0 = no freezing of receive signaling data will occur

1 = allow freezing of receive signaling data at RSIG (and RSER if

CCR4.7 = 1).

RFF

CCR4.3

Receive Force Freeze. Freezes receive side signaling at RSIG (and

RSER if CCR4.7=1); will override Receive Freeze Enable (RFE).

See Section 7.2 for details.

0 = do not force a freeze event

1 = force a freeze event

THSE

CCR4.2

Transmit Hardware Signaling Insertion Enable. See Section 7.2

for details.

0 = do not insert signaling from the TSIG pin into the data stream

presented at the TSER pin

1 = insert the signaling from the TSIG pin into data stream presented

at the TSER pin

TPCSI

CCR4.1

Transmit Per-Channel Signaling Insert. See Section 7.2 for

details.

0 = do not use TCHBLK to determine which channels should have

signaling inserted from TSIG

1 = use TCHBLK to determine which channels should have

signaling inserted from TSIG

TIRFS

CCR4.0

Transmit Idle Registers (TIR) Function Select. See Section 8 for

timing details.

0 = TIRs define in which channels to insert idle code

1 = TIRs define in which channels to insert data from RSER (i.e.,

Per-Channel Loopback function)
