Log in to the VLNC6x circuit pack being provisioned.

From the Navigation menu, select Timing → Interface Timing → Configuration.

Result:

The Interface Timing Configuration screen appears.

Enter the required parameters, then click Submit.

Parameters include:

• Port: Specifies the DS1/E1 interface to be provisioned.

• Timing Source: Specifies the timing source for the DS1/E1 interface.

  System- The source of timing is derived from the configured System Timing Source.

  Loop - The timing is derived from the received DS1/E1 signal and is used to synchronize the transmitted DS1/E1 signal.

  Differential - The timing is recovered from the RTP differential timestamps on the incoming Pseudowire packet for the DS1/E1. The reference timing for recovery of this clock is the configured System Timing Source.

  The Differential timing source is not supported when the Synchronous Ethernet Transmit Mode is enabled on the following circuit packs:

  • VLNC64 - series number S1:1

  • VLNC61 - series number S1:2

  • VLNC60 - any series number.

  If the RTP header is planned to be disabled on the Pseudowire transmission then the differential option should not be used.

• Differential Timing Domain: Specifies the differential timing domain being used to generate and recover the differential timestamps on VLNC64 circuit packs.

If provisioning a VLNC64 circuit pack, select Timing → Interface → Differential Timing Domain Summary and verify that the required parameters are provisioned correctly.

Result:

The Differential Timing Domain Summary screen appears.
