Ring MS

In this user interface, you can configure and maintain ring multiplex section protection (MSP) station by station.

Navigation Path

In the NE Explorer, select an NE and choose Configuration > Ring MS from the Function Tree.

Buttons

Button		Description
Start Protocol		Starts the automatic protection switching (APS) protocol.
Stop Protocol		Stops the APS protocol.
Query	Query Protection Group	Queries the switching status and protocol status of protection groups from the NE.
Query	Query Switching Status	Queries the switching status of the protection group from the NE.

Shortcut Menu Items

Menu	Description
Query	Queries the switching status of Ring MS.
Clear	Clears the switching status of Ring MS.
Lockout of Protection - Span	The switching request for the Ring MS is denied, but the reversion of the switching is allowed.
Lockout of Working Channels - Ring Switch
Lockout of Protection - All Spans
Forced Switching to Protection - Ring	Switches a Ring MS forcibly, regardless of the status of the Ring MS. NOTICE: When the switching operation are performed, the services may be interrupted.
Manual Switching to Protection - Ring	Performs manual switching from the working channel to the protection channel. If the protection channel is normal, the switching takes place. If the protection channel fails or must meet a switching request of higher priority, the switching does not occur. NOTICE: When the switching operation are performed, the services may be interrupted.
Exercise - Ring	Simulates the switching operation. It is not a real switching. This function tests the function of the protection group and does not interrupt services.

Parameters

Field	Value		Description
Protection Group ID	Example: 1		The ID of the MS protection group.
Transmission Level	STM-1, STM-4, STM-16, STM-64 Default: STM-1		The rate level of the ring MS protection group.
Protection Type	2-fiber Bidirectional Multiplex Section, 4-fiber Bidirectional Multiplex Section		The protection type of the MSP ring.
Local Node ID	Default: 0		The local node number of the MSP ring.
West Node ID	Example: 2		The number of the west node that is adjacent to the local node. Applied to release 5.0 NEs only.
East Node ID	Example: 1		The number of the east node that is adjacent to the local node. Applied to release 5.0 NEs only.
WTR Time (s)	Example: 300		The WTR time of the MSP ring.
SD Switching	Enabled, Disabled Default: Enabled		Sets whether to enable SD to serve as the MS switching condition.
Protocol Type	New Protocol, Restructure Protocol Default: New Protocol		The type of MSP protocol. New Protocol: Optimized based on the old protocol and is applicable to the equipment of mainstream versions. Currently it is a widely used protocol. Restructure Protocol: Optimized based on the new protocol and provides better protocol protection measures to make the protocol stabler. A combination of these protocols leads to an NE interconnection failure. Hence, ensure the same protocol type is used by the interconnected NEs.
Protocol Status	Unstarted, Already Started, Being Started, Partially Enabled, Unknown		The status of MSP protocol.
Slot Mapping Settings	Slot Mapping Direction	West Line 1, East Line 1, West Line 2, East Line 2	The mapping direction of the logical system.
	Mapped Board	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: slot number-board name-port number(port name)	The mapping slot in the service direction of the logical system.
	Switching Status	Example: Forced Switching, Manual Switching, Exercise	The switching status of the mapping direction.
	Remote End/Local End	Remote, Local	When the protection group is in Dual-Ended Switching mode, displays whether the switching request is from the remote end or the local end.
	Select Mapping Direction	West Line 1, East Line 1, West Line 2, East Line 2	Choose the mapping direction of the Ring MS.
	Mapped Boards	Equipment that supports the master and slave shelf management: Mapping direction - shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: Mapping direction - slot number-board name-port number(port name)	The mapping slot in the service direction of the logical system.
	Available Boards	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: slot number-board name-port number(port name)	Choose the mapping slot in the service direction of the Ring MS.
Map as VC4	Checked, Unchecked		Set the mapping mode displayed in unit of VC4. This option is available for the equipment that supports the function.
Hold-Off Time (100ms)	0 to 100		Sets the hold-off time of the MSP ring switch.
