SNCP Service Control

Function

Query Switching Status

Queries the protection group status.

Clear

Clears switching for the selected port.

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. Regardless of the status of the working and protection channels, the services are locked in the working channel.

Protection Group ID

For example: 1

Displays the ID of the protection group.

Service Type

SNCP

Displays the service protection type.

Source

• 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)

Displays the service source timeslot of the service.

Sink

• 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)

Displays the service sink timeslot of the service.

Level

VC12, VC3, VC4

Displays the service level.

Current Status

Normal, Lockout, Forced Switching, Forced Switching to Working, Forced Switching to Protection, SF Switching, SD Switching, Manual Switching, Manual Switching to Working, Manual Switching to Protection, Automatic Switching, WTR, DNR, Unknown

Displays the current switching status of the protection group.

Revertive Mode

Revertive, Non-Revertive

Displays the revertive 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.

Hold-Off Time (100ms)

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.

Switching Condition

TIM, EXC, SD, UNEQ, SLM, BIPOVER

Sets the startup conditions that trigger service protection switching.

Service Origin

Create Manually, Intelligently Generate

Displays the service origin.

Active Channel

For example: Delaying to Start

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

Switching Request

For example: SF Switching

Displays the current switching request.
