[APS Option]
Default:
Nonrever-
tive
Range: N/A
Format: Predefined
Indicates that once the active status has switched from
the working module to the protection module, the
active status cannot revert automatically to the work-
ing module.
Working SF BER
Default:
TenToMinu
s4
Range: N/A
Format: Predefined
Specifies the signal-failure bit error rate (SF BER)
threshold on the working module port. When the BER
exceeds the threshold, the system switches the active
status from the working module to the protection
module.
TenToMinus4
Selects an SF BER of 10
-4
for an extremely low quality
signal threshold.
TenToMinus5
Selects an SF BER of 10
-5
for a very low quality signal
threshold, which indicates a signal failure (SF).
Working SD BER
Default:
Default:
TenToMinus5
Range: N/A
Format: Predefined
Specifies the signal-degraded bit error rate (SD BER)
value on the working module port.
TenToMinus5
10
-5
(lowest quality threshold, indicates that the signal
is “signal degraded” (SD).
TenToMinus6
10
-6
(lower than 10
-7
quality threshold).
TenToMinus7
10
-7
(lower than 10
-8
quality threshold).
TenToMinus8
10
-8
(low quality).
Protection SF BER
Default:
TenToMinu
s4
Range: 10
-4
– 10
-5
Format: Predefined
Specifies the signal-failure bit error rate (SF BER) for
the protection module port. When the BER value on
the protection port exceeds the threshold value, the
system switches the active status from the protection
module to the working module.
TenToMinus4
10
-4
(extremely low quality signal).
TenToMinus5
10
-5
(very low quality signal, indicates a failed signal
(SF)).
Protection SD BER
Default:
TenToMinu
s5
Range: N/A
Format: Predefined
Specifies the signal-degraded bit error rate (SD BER)
value on the APS protection module port.
TenToMinus5
10
5
(lowest quality threshold, indicates a “signal
degraded” (SD) status).
TenToMinus6
10
6,
(lower than 10
-7
quality threshold).
TenToMinus7
10
5
, (lower than 10
-8
quality threshold).
TenToMinus8
10
-8
(low quality).
