Description

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

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

Query

Queries the attributes and statuses for all SNCP services from the NE.

Apply

Applies the configuration to the NE.

Description

Source Channel
  • 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 service source timeslot of the service.

Service Sink
  • 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 service sink timeslot of the service.

Level

GE, Any, ODU1, ODU2, ODU3, ODU5G

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.

Delay 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.

SNCP Type

SW SNCP, SNC/I, SNC/N, SNC/S, MSSNCP

Displays the protection type of a service.

OTN Level

PM, TCM1, TCM2, TCM3, TCM4, TCM5, TCM6

Displays the OTN level of a service.

SD Enabling Flag

Enabled, Disabled

Sets the SD enabling flag.

ODUflex Service Type

For example: FC400
Indicate the service type of the configured port.
NOTE:

Set this parameter when Service Type of a WDM cross-connection is ODUflex.

Occupied ODTUk Timeslots

1 to 8
Indicates the quantity of ODUflex timeslots.
NOTE:
  • Set this parameter when Level of a WDM cross-connection is ODUflex and Service Type is Custom or PACKET.
  • The quantity of ODUflex timeslots ranges from 1 to 8, and the rate that ODUflex supports is 1.25 Gbit/s (1 x 1.25 Gbit/s) to 10 Gbit/s (8 x 1.25 Gbit/s).
Recommended value for Occupied ODTUk Timeslots:
  • Calculation formula: recommended quantity of occupied ODTUk timeslots = service rate of the port/ODU0 rate (1.25 Gbit/s). If the result is not an integer, the timeslot quantity is the integer number of the result plus 1.
  • Principle:
    • If the source and sink boards are tributary and line boards respectively, the recommended timeslot quantity is that of the tributary board service.
    • If the source and sink boards are line boards, there is no the recommended timeslot quantity.

Service Rate(bit/s)

1 to 9993964557
Indicates or sets the service rate.
NOTE:

Set this parameter when Level of a WDM cross-connection is ODUflex and Service Type is Custom.

Current Channel

For example: Delaying to Start

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