NAME AND DESCRIPTION
ECUS
CCR2.7
Error Counter Update Select. See Section 7 for details.
0 = update error counters once a second
1 = update error counters every 62.5ms (500 frames)
VCRFS
CCR2.6
VCR Function Select. See Section 7.1 for details.
0 = count BiPolar Violations (BPVs)
1 = count Code Violations (CVs)
AAIS
CCR2.5
Automatic Transmit AIS Generation.
0 = disabled
1 = enabled
ARA
CCR2.4
Automatic Remote Alarm Generation.
0 = disabled
1 = enabled
RSERC
CCR2.3
RSER Control.
0 = allow RSER to output data as received under all conditions
1 = force RSER to one under loss of frame alignment conditions
LOTCMC
CCR2.2
Loss of Transmit Clock Mux Control. Determines whether the
transmit-side formatter should switch to the ever-present RCLKO if the
TCLK should fail to transition (see Figure 2-1).
0 = do not switch to RCLKO if TCLK stops
1 = switch to RCLKO if TCLK stops
RFF
CCR2.1
Receive Force Freeze. Freezes receive-side signaling at RSIG (and TS16
in RSER if CCR3.3 = 1); will override Receive Freeze Enable (RFE).
See Section 9 for details.
0 = do not force a freeze event
1 = force a freeze event
RFE
CCR2.0
Receive Freeze Enable. See Section 9 for details.
0 = no freezing of receive signaling data will occur
1 = allow freezing of receive signaling data at RSIG (and TS16 in RSER
if CCR3.3 = 1).
