Optical Wavelength Shared Protection

In this user interface, you can create an optical wavelength shared protection (OWSP) group, query the OWSP group status, and delete the OWSP group. The OWSP ring supports a maximum of eight stations.

Navigation Path

In the NE Explorer, choose Configuration > Optical Wavelength Shared Protection from the Function Tree.

Buttons

Button	Description

Shortcut Menu Items

Menu	Description
Refresh OTU List	Queries the OTU boards that correspond to the West OTU and East OTU.
Bound Span ID	Sets the span IDs for the West Working Channel and East Working Channel.
Unbound Span ID	Deletes the span ID.
Lockout	Locks the switching status of the protection group. Regardless of the status of the working and protection channels, the services are locked in the working channel.
Forced Switching - Ring	Forcibly switches the service from the working channel to the protection channel.
Manual Switching - Ring	Manually switches the protection group.
Exercise Switching - Ring	Simulates a switching. It is not a real switching.
Clear	Clears the switching status of a selected protection group.

Parameters

Table 1 lists the parameters in the Protocol Channel tab.

Table 2 lists the parameters in the OWSP Protection tab.

**Table 1** Protocol Channel Parameters
Field	Value	Description
ID	1 to 255	Protocol channel ID that is automatically assigned by the system. It is a physical ring of the OSC board.
West Protocol Channel	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)	Specified west protocol channel when protocol channels are created. NOTE: The west and east protocol channels cannot be identical. In the case of an SC2 board, two optical interfaces of the same SC2 board must be used. In the case of an SC1 board, two SC1 boards must be inserted in paired slots. When you configure a protocol channel, the SC1 or SC2 board must be in the main subrack.
East Protocol Channel	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)	Specified east protocol channel when protocol channels are created.
Ring ID	1 to 40	Each protocol channel ID corresponds to ring IDs of 40 sub protocol channels.
Ring ID Usage	Used, Unused	Indicates whether the ring ID of a sub protocol channel is used.

**Table 2** OWSP Protection Parameters
Field	Value	Description
Protection Group ID	1 to 65535	Protection group identifier that is automatically assigned by the system.
Protocol Channel	NE name-West (shelf ID(shelf name)-slot number-board name-port number(port name))-East (shelf ID(shelf name)-slot number-board name-port number(port name))	Indicates the configuration of the protocol channel of the current node.
Switching Status	Stopped, Starting, Idle, East Switching, West Switching, Full Pass-Through, APS Pass-Through	Indicates the current switching status.
Switching Request - West	Lockout Protection SF SF Ring Switching - Working SF Protection SF SF Ring Switching - Working SD Protection SF SF Ring Switching - Working SF Protection SD SF Ring Switching - Working SF Protection OK Forced Switching - Ring Protection SD, SD Ring Switching - Working SD Protection SD SD Ring Switching - Working SD Protection OK Manual Switching - Ring WTR - Ring Switching Exercise Switching - Ring No Request	Indicates the current west switching request.

WTR Time (mm:ss)	5:00 to 12:00	Indicates the delay before the service is switched from the protection channel to the working channel when the working channel becomes normal.
West OTU	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)	Indicates the OTU board connected with the west DCP board. It can be automatically queried according to the fiber connection relation. If this parameter is set to No, the SD the OTU detects in this direction is not taken as a switching condition. When a specific board is set, and the SD Enabling Flag is Enabled, the SD of this board is taken as a switching condition.
East OTU	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)	Indicates the OTU board connected with the east DCP board. It can be automatically queried according to the fiber connection relation. If this parameter is set to No, the SD the OTU detects in this direction is not taken as a switching condition. When a specific board is set, and the SD Enabling Flag is Enabled, the SD of this board is taken as a switching condition.
SD Switching	Enabled, Disabled	You can enable or disable the SD only after setting the west or east OTU.
Remote/Near End - West	Near-End, Remote-End	Indicates whether the switching is performed at the transmit end or the respond end of the service. Near-End: Indicates the local node, that is, the transmit end of the service. Remote-End: Indicates the west adjacent node, that is, the respond end of the service.
Remote/Near End - East	Near-End, Remote-End	Indicates whether the switching is performed at the transmit end or the respond end of the service. Near-End: Indicates the local node, that is, the transmit end of the service. Remote-End: Indicates the east adjacent node, that is, the respond end of the service.
Protection Channel Direction	West Working Channel West Protection Channel East Working Channel East Protection Channel	Indicates the protection group unit. A complete protection group must contain all the units.
Channel Information	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)	Indicates the channel information in the corresponding direction.
Span ID	0 to 31	The ID of 0 indicates a deletion operation. In the same protection ring, span IDs cannot be duplicate. NOTE: The span ID ranges from 1 to 31. The west span ID must be different from the east span ID.
Hold-Off Time (0.1s)	0 to 100 Default value: 0	Indicates the delay before a service is switched from the current working channel to another channel. The hold-off time effectively avoids repeated switching when the service status is unstable. The hold-off time in each direction can be set according to the corresponding link status.
Channel Status	Normal, SD, SF, Unmonitored, Unknown	Indicates the channel status in the corresponding direction.
NE for Protocol Channel	For example: NE470	Displays the NE for the protocol channel.
Select Mapping Direction	West, East	Sets the direction of board mapping to east or west.
