NAME AND DESCRIPTION
RSRE
CCR4.7
Receive Side Signaling Re–Insertion Enable. See Section 10.2 for details.
0 = do not re–insert signaling bits into the data stream presented at the RSER pin
1 = reinsert the signaling bits into data stream presented at the RSER pin
RPCSI
CCR4.6
Receive Per–Channel Signaling Insert. See Section 10.2 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 Ones. See Section 10.2 for more details.
0 = do not force extracted robbed–bit signaling bit positions to a one
1 = force extracted robbed–bit signaling bit positions to a one
RFE
CCR4.4
Receive Freeze Enable. See Section 10.2 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 10.2 for details.
0 = do not force a freeze event
1 = force a freeze event
THSE
CCR4.2
Transmit Hardware Signaling Insertion Enable. See Section 10.2 for details.
0 = do not insert signaling from the TSIG pin into the data stream presented at the
TSER pin
1 = insert signaling from the TSIG pin into data stream presented at the TSER pin
TPCSI
CCR4.1
Transmit Per–Channel Signaling Insert. See Section 10.2 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 2.1 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)
