SYMBOL POSITION 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)
