Important!
The System Timing Source parameter must be provisioned to GE for SyncE Line timing.
Enter the required System Timing Source and Differential Timestamp Frequency (VLNC6x circuit packs only) parameters, then click Submit.

From the Navigation menu, select Timing → System Timing → Summary and verify that the system timing parameters were provisioned correctly.
Result:
The System Timing Summary screen appears.

From the Navigation menu, select Timing → SynchE Timing → Configuration.
Result:
The SyncE Timing Configuration screen appears.

Enter the required parameters to configure Synchronous Ethernet for Ethernet interfaces, then click Submit.
Parameters include:
-
SynchE Mode: Specifies the Synchronous Ethernet ITU-T G.8262 EEC-Option 1 (SDH) or EEC-Option 2 (SONET) Standards mode for VLNC42 circuit packs only.
The SynchE Mode is a display-only parameter for the VLNC6x circuit packs. To change the Interface Mode for VLNC6x circuit packs, select PDH/TDM → Pack Configuration.
-
SyncE TX Mode: Enables/Disables SyncE timing in the transmit direction on VLNC6x circuit packs only. SyncE timing out is supported on the backplane for adjacent circuit packs and on enabled Ethernet interface The synchronous Ethernet transmit mode is not supported if any of the T1/E1 interfaces have the timing source provisioned differential on the following circuit packs:
-
VLNC64 - series number S1:1
-
VLNC61 - series number S1:2
-
VLNC60 - any series number.
-
Auto Reconfigure: Enables/disables the SyncE automatic synchronization reference switching between the Primary and Secondary SyncE GE selected interface. The System Timing Source must be configured to GE.
-
Revertive: Enables/Disables revertive SyncE references switching mode. SyncE synchronization reference switching is performed between the Primary and Secondary SyncE GE selected interface. The System Timing Source must be configured to GE and Auto Reconfigure must be Enabled.
When enabled, revertive SyncE reference switching is performed. When disabled, nonrevertive SyncE reference switching is performed.

From the Navigation menu, select Timing → SynchE Timing → Interface SyncE.
Result:
The Interface SyncE screen appears.

Enter the required parameters to enables SyncE support on the specified Ethernet interface, then click Submit.
Parameters include:
-
Interface Number: Specifies the SyncE Fast Ethernet or Gigabit Ethernet interface to be provisioned.
-
SyncE Support Type: Specifies the type of SyncE support for the SyncE interface.
None removes the SyncE support from the interface
SyncE Out applies to the SFP-based GE, backplane GE, and FE ports.
Primary, Secondary, and Primary-Lock apply to SFP-based GE ports when the System Timing Source is configured as GE.
Tunnel-SSM applies to GE interfaces. Connect GE interfaces to the adjacent pack via either backplane port or PTM. For VLNC42/42B circuit packs, the System Timing Source must be configured GE. For VLNC6x and VLNC55 circuit packs, the System Timing Source must be configured Backplane.
