SNCTP

Query Protection Group

Queries the existing SNCTP protection groups.

Query Switch Status

Queries the channel protection status.

Query

Queries the channel protection status.

Clear

Clears switching for the selected channel.

Force to Protection

Forces the service to switch from the working channel to the protection channel. This switching is performed regardless of the protection channel state, unless the protection channel is satisfying a higher priority bridging request.

Force to Working

Forces services to switch from the protection channel to the working channel. This switching is performed regardless of the working channel state, unless the working channel is satisfying a higher priority bridging request.

Manual to Protection

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 has a failure or must satisfy higher priority switching, the switching does not take place.

Manual to Working

Performs manual switching from the protection channel to the working channel. If the working channel is normal, the switching takes place. If the working channel has a failure or must satisfy higher priority switching, the switching does not take place.

Lockout of Protection

The switching request for the port is denied, but the reversion of switching is allowed.

Protect Group ID

For example: 1

Displays the protection group ID.

Revertive Mode

Revertive, Non-Revertive

Displays the revertion mode. Whether the working service is switched back from the protection service after it returns normal.

WTR Time (s)

300 to 720

Sets the wait-to-restore time. Refer to the period of time starting when it is detected the working service returns to normal and ending when the working service is switched back after the protection switching. If the revertive mode is non-revertive, skip this step.

Working Channel Hold-Off Time (100 ms)

For example: 0 to 100, in the unit of 100 milliseconds

Sets a period of time starts when the system detects signal degrade and ends when service switching occurs, so as to avoid duplicate switching when the service status is unstable. Sets 100 milliseconds as the unit time for switching. 5 indicates that the hold-off time is 500 milliseconds.

Working Channel - Switching Condition

TIM, EXC, SD, UNEQ

Default: Null

Sets the startup conditions that trigger service protection switching.

Protection Channel Hold-Off Time (100 ms)

For example: 0 to 100, in the unit of 100 milliseconds

Sets a period of time starts when the system detects signal degrade and ends when service switching occurs, so as to avoid duplicate switching when the service status is unstable. Sets 100 milliseconds as the unit time for switching. 5 indicates that the hold-off time is 500 milliseconds.

Protection Channel - Switching Condition

TIM, EXC, SD, UNEQ

Default: Null

Sets the startup conditions that trigger service protection switching.

Switching Status

Lockout, Forced Switching, Manual Switching, WTR, SD Switching, SF Switching, Unknown, Normal

Displays the switching status of the protection group.

Active Channel

For example: Working Unit

Displays what the current protection group selectively receives: the working or the protection service.

Service Origin

Create Manually, Intelligently Generate

Displays the creation mode of the service.

When the value is Intelligently Generate, the user can only query the service, and cannot modify the service settings.

Timeslot Mapping

For example: Slot ID-Board Name-Optical Interface No. (name)-VC4:1

Displays the timeslots that are mapped to the working and protection units.

Unit Type

Working Channel, Protection Channel

Displays the working channel and the protection channel of the protection unit.

Status

Normal, SF, SD, Unknown

Displays the current status of the working and protection units.

Working Time Slot Range

1 to 64

Sets the timeslot range.

Working 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)

Selects the working channel.

Protection Time Slot Range

1 to 64

Sets the timeslot range.

Protection 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)

Selects the protection channel.

Working Channel Timeslot Mapping

• Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name-port number(port name)-channel number
• Equipment that does not support the master and slave shelf management: slot number-board name-port number(port name)-channel number

Displays the working channel timeslot mapping.

Protection Channel Timeslot Mapping

• Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name-port number(port name)-channel number
• Equipment that does not support the master and slave shelf management: slot number-board name-port number(port name)-channel number

Displays the protection channel timeslot mapping.
