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 signal-
ing re–inserted
1 = use RCHBLK to determine which channels should have signaling re–in-
serted
RFSA1 CCR4.5 Receive Force Signaling All Ones. See Section 7.2 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 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 Sec-
tion 7.2 for details.
0 = do not force a freeze event
1 = force a freeze event
TSRE CCR4.2 Transmit Side Signaling Re–Insertion Enable. See Section 7.2 for
details.
0 = do not re–insert signaling bits into the data stream presented at the
TSER pin
1 = re–insert the signaling bits 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
re–inserted
1 = use TCHBLK to determine which channels should have signaling re–in-
serted
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)
CCR5: COMMON CONTROL REGISTER 5 (Address=19 Hex)
(MSB) (LSB)
TJC LLB LIAIS TCM4 TCM3 TCM2 TCM1 TCM0
SYMBOL POSITION NAME AND DESCRIPTION
TJC CCR5.7 Transmit Japanese CRC6 Enable.
0 = use ANSI/AT&T/ITU CRC6 calculation (normal operation)
1 = use Japanese standard JT–G704 CRC6 calculation
LLB CCR5.6 Local Loopback.
0 = loopback disabled
1 = loopback enabled
LIAIS CCR5.5 Line Interface AIS Generation Enable. See Figure 1–1 for details.
0 = allow normal data from TPOSI/TNEGI to be transmitted at TTIP and
TRING
1 = force unframed all ones to be transmitted at TTIP and TRING
