SDH/PDH Service Management

In this user interface, you can configure line and tributary services for stations, such as services at VC4, VC3 and VC12 levels. In addition, you can configure SNCP services and other services. You can also query and delete cross-connections and print the cross-connection information. During the configuration, if the new service is not configured correctly, the Web LCT does not deliver the settings to NEs and a prompt is displayed automatically.

Navigation Path

In the NE Explorer, click an NE and choose Configuration > SDH/PDH Service Management from the Function Tree.

Buttons

Button	Description
Create SNCP	Displays a dialog box for the user to create the SNCP service.
To Normal	Converts an SNCP service to a normal service.
To SNCP	Converts a normal service to an SNCP service. This button is available only when services are expanded and displayed as unidirectional services.
Filter	Sets the filter criteria, including Level, Source Port, Sink Port, Source VC4, and Sink VC4.
Display	Displays all services separately as unidirectional services or bidirectional services regardless of whether the channel numbers are consecutive or not.
Scheme	Selects the numbering scheme for VC12 timeslots. The two schemes are Sequential Mode (ITU-T) and interleaved cross-connection.

Parameters

Field	Value	Description
Level	VC12, VC3, VC4	Specifies the level of the newly created service.
Type	,,,,,,,,	indicates that a service passes through the line bidirectionally. indicates that a service passes through the line unidirectionally. indicates a service is dropped from the line to the tributary (unidirectional). indicates a service is added from the tributary to the line (unidirectional). indicates that a service is added from the tributary to the line and also dropped from the line to the tributary (bidirectional). indicates that the service passes through the same line board unidirectionally. indicates that the service passes through between two timeslots of the same line board bidirectionally. indicates that the service passes through the same tributary board unidirectionally. indicates that the service passes through between two timeslots of the same tributary board or two tributary boards of the same node bidirectionally.
Source (Sink) Slot	Format: Slot ID-Board Name-Port	Specifies the service source (sink) slot.
Source (Sink) Timeslot/Path	For example: VC4:1:1	Displays the source (sink) timeslot or channel that the cross-connection services uses.
E1 Priority	High, Low, None	Sets the priority of a VC12 service. When the priority of a service is set to High, transmission of the service is guaranteed first if the channel is deteriorated. When the priority of a service is set to Low, the service is discarded first if the channel is deteriorated. When the priority of a service is set to None, the service is discarded randomly if the channel is deteriorated. NOTE: This parameter is configurable only when Enable E1 Priority is set to Enable.
Direction	Bidirectional, Unidirectional	The service received and transmitted through the same route is called bidirectional service, while the service received and transmitted through different routes is called unidirectional service.
Source (Sink) Port	For example: 1	Sets the source (sink) ports of the service.
Source (Sink) VC4	For example: VC4-1	Selects the source (sink) VC4. This parameter is unavailable if a tributary board is selected for Source (Sink) Slot.
Source (Sink) Timeslot Range (e.g.1,3-6)	For example: 1	Sets the specific timeslot or timeslot range of the service. The format of inputting multiple consecutive timeslots: start timeslot number - end timeslot number. The format of inputting multiple inconsecutive timeslots: ts1,ts2.... Two formats can be used together. The range can be different for different levels of services or different boards.
Service Type	SNCP	Specifies the service type of the newly created SNCP service.
Revertive Mode	Revertive, Non-Revertive	Specifies whether to switch back to the original working service after removing the fault. Select Revertive to switch back to the working service, or select Non-Revertive not to switch back to the working service any longer.
Hold-off Time (100ms)	0 to 100 Default: 0	Sets the hold-off time for the NE.
WTR Time (s)	300 to 720	Sets the WTR time for the NE.
