NAME AND DESCRIPTION
TESE
CCR3.7
Transmit-Side Elastic Store Enable.
0 = elastic store is bypassed
1 = elastic store is enabled
TCBFS
CCR3.6
Transmit Channel Blocking Registers (TCBR) Function Select.
0 = TCBRs define the operation of the TCHBLK output pin
1 = TCBRs define which signaling bits are to be inserted
TIRFS
CCR3.5
Transmit Idle Registers (TIR) Function Select. See Section 10.1 for
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-
Cannel Loopback function)
-
CCR3.4
Not Assigned. Should be set to zero when written to.
RSRE
CCR3.3
Receive-Side Signaling Reinsertion Enable. See Section 10.2 for details.
0 = do not reinsert signaling bits into the data stream presented at the
RSER pin
1 = reinsert the signaling bits into data stream presented at the RSER pin
THSE
CCR3.2
Transmit-Side Hardware Signaling Insertion Enable. See Section 10.1
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 the data stream presented at
the TSER pin
TBCS
CCR3.1
Transmit-Side Backplane Clock Select.
0 = if TSYSCLK is 1.544MHz
1 = if TSYSCLK is 2.048MHz/4.096MHz/8.192MHz
RCLA
CCR3.0
Receive Carrier Loss (RCL) Alternate Criteria.
0 = RCL declared upon 255 consecutive zeros (125
ms)
1 = RCL declared upon 2048 consecutive zeros (1ms)
