- Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)(-monitoring level)
NOTE: For details about the differences between the standard and compatibility modes, see the Impacts of the Standard Mode on the Web LCT in Channel Model (OTU, Line or PID Board).
|
Displays the object that the TCM overhead monitors.
|
Level
|
TCM1, TCM2, TCM3, TCM4, TCM5, TCM6
|
Displays the TCM layer.
You can divide the services into layers for management.
|
TCM Status
|
Unused, Used, Reserved, LCK, OCI, AIS
|
Displays the current status of the TCM layer.
|
Source Mode
|
Transparent Mode, Operation Mode
Default: Transparent Mode
|
The Source Mode parameter
specifies the mode that the TCM source end uses to process the TCM
overhead of the transmitted OTN signal. |
Sink Mode
|
Transparent Mode, Operation Mode, Monitoring
Mode
Default: Transparent Mode
|
The Sink Mode parameter
specifies the mode for processing the TCM overhead of the downstream
station.
|
TIM Mode
|
Only SAPI, Only DAPI, SAPI&DAPI, No Detection
Default: No Detection
|
The TIM Mode parameter is used to set the mode for detecting the OTN trail trace identifier (TTI).
|
Source Enable Status
|
Enabled, Disabled
Default: Disabled
|
The Source Enable Status parameter specifies the state of the source end of the TCM
layer. In this way, the system determines whether to monitor the TCM
overhead of the transmitted OTN signals based on the specified TCM
mode.
|
Sink Enable Status
|
Enabled, Disabled
Default: Disabled
|
The Sink Enable Status parameter specifies the state of the sink end of the TCM layer.
In this way, the system determines whether to monitor the TCM overhead
and alarms based on the specified TCM Mode.
|
TTI to Be Sent
|
64 characters
Default: None
|
The TTI to Be Sent parameter is used to set the trail trace identifier (TTI) that should be sent of the OTN path monitoring overhead layer.
|
TTI to Be Received
|
A string of 64 characters
Default: None
|
The TTI to Be Received parameter is used to define the TTI to be received at the receive end. The trail trace identifier (TTI) is a string of 64 characters,
including 15 characters used as the source access point identifier, 15 characters used as the sink access point identifier, two characters of 0s, and 32 characters that are defined by carriers.
NOTE: Right-click the field of the TTI to be Sent or TTI to be Received parameter and choose from the shortcut menu to
copy the overhead bytes to be sent or received. This will improve the work efficiency.
|
TTI Received
|
A string of 64 characters
Default: None
|
The TTI Received parameter
specifies the TTI from the upstream NE that the local NE actually
receives.
NOTE: The value of TTI Received must be the same as the value of TTI to be Received. Otherwise, an ODUk_PM_TIM alarm is reported.
|
LCK Insertion
|
Enabled, Disabled
Default: Disabled
|
Sets whether to turn on the LCK insertion function.
When the function is Enabled, an LCK signal is inserted to the downstream for locking the signal of the user access point. This function is often used by carriers
for a test.
NOTICE: Configuring the parameter LCK Insertion as Enabled may interrupt service.
|
Threshold-Crossing Threshold
|
1.0E-3, 1.0E-4, 1.0E-5
Default: 1.0E-3
|
The Threshold-Crossing Threshold parameter specifies the threshold of the signal BER for generating
a BER threshold crossing alarm.
|
Degrade Threshold
|
1.0E-5, 1.0E-6, 1.0E-7, 1.0E-8, 1.0E-9
Default: 1.0E-6
|
The Degrade Threshold parameter specifies the degrade threshold of the BIP8 BER.
|
Config TCM Ason Alarm
|
Enabled, Disabled
|
Specifies whether to support TCM alarms for ASON trails. This parameter applies to the ASON trails that traverse third-party NEs.
|
Non-Intrusive Monitoring
|
Enabled, Disabled
Default: Disabled
|
The Non-Intrusive Monitoring parameter provides an option for enabling or disabling the
non-intrusive monitoring.
|
DEG Threshold
|
1.25G: 1-10167; Default: 1.25G: 3050
2.5G: 1-20420; Default: 2.5G: 6126
5G: 1-41012; Default: 5G: 12303
10G: 1-82025; Default: 10G: 24607
40G: 1-329491; Default: 40G: 98847
100G: 1-856387; Default: 100G: 256916
|
The DEG Threshold parameter specifies the degrade threshold. If BIP8 BER exceeds the degrade threshold during a specified
detection period, the system assumes that a BER threshold crossing event occurs in that period. One second is a detection period. If BER exceeds the degrade threshold continuously during the specified detection period, the ODUk_TCMn_DEG alarm is reported.
|
DEG Detection Time
|
1-10
Default: 7
|
The DEG Detection Time parameter indicates that the ODUk_TCMn_DEG alarm is reported when the DEG errors exceed the threshold continuously during the time
as specified by the parameter (1s as one detection period).
|
BIP8 Detection Mode
|
Poisson, Bursty
Default: Vary with different boards
|
The BIP8 Detection Mode parameter specifies the mode for detecting BIP8 errors.
|
Enable TIM Response
|
Disabled, Enabled
Default: Disabled
|
Sets whether to enable the TIM follow-up response or not. When a TIM alarm is generated at this end, an AIS alarm is inserted to services in the downstream direction. This interrupts the services in the downstream direction.
|
Enable LTC Response
|
Disabled, Enabled
Default: Disabled
|
Sets whether to enable the LTC follow-up response or not.
|
DEG Detection Time Window(ms)
|
10, 100, 1000
Default: 1000
|
Set the interval time silce of DEG.
