DLP-D70 Set Up Internal Timing

–Timing Mode set to Line—Your options are the node’s working OC-N cards (non-DWDM nodes), or OSC cards (DWDM nodes) and Internal Clock. Select the cards/ports that are directly or indirectly connected to the node wired to the BITS source, that is, select the node’s trunk cards. Set Reference 1 to the trunk card that is closest to the BITS source. For example, if Slot 5 is connected to the node wired to the BITS source, select Slot 5 as Reference 1.

–Timing Mode set to Mixed—Both BITS and optical cards are available, allowing you to set a mixture of external BITS and optical trunk (span) cards as timing references.

•BITS-1 Out/BITS-2 Out—Define the timing references for equipment connected to the Timing A Out or Timing B Out FMEC connector. Normally, Timing Out is used with line nodes, so the options displayed are the working optical cards. Timing A Out and Timing B Out are enabled as soon as BITS-1 and BITS-2 facilities are placed in service.

Step 6 Click Apply.

Note Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for timing-related alarms.

DLP-D70 Set Up Internal Timing

Purpose

This task sets up internal timing (Stratum 3) for an ONS 15454 SDH.

Tools/Equipment

None

Prerequisite Procedures

DLP-D60 Log into CTC, page 3-24

Required/As Needed

As needed (use only if a BITS source is not available)

Onsite/Remote

Onsite or remote

Security Level

Provisioning or higher

Caution Internal timing is Stratum 3 and not intended for permanent use. All ONS 15454 SDH nodes should be timed to a Stratum 2 or better primary reference source.

Note CTC refers to Timing A and Timing B as BITS-1 and BITS-2. The MIC-C/T/P FMEC connector is labeled as Timing A and Timing B.

Step 1 In node view, click the Provisioning > Timing tabs.

Step 2 In the General Timing area, enter the following:

•Timing Mode—Choose External.

•Revertive—Not applicable for internal timing; the default setting (checked) is sufficient.

•Reversion Time—Not applicable; leave unchanged. For internal timing, the default setting (5 minutes) is sufficient.

Step 3 In the BITS Facilities area, enter the following information:
