4.2.4 Setup NE Timing Source

The Setup-Timing Source Configuration dialog box is used to setup the NE timing

source.

Addition of a new timing source is configured in the Set Timing Source dialog box by

clicking the Add button on the upper left of the Setup-Timing Source Configuration

dialog box. Perform the procedure described in the subsection 4.2.4.2 Procedure: Add

New NE Timing Source.

Modification and deletion of a timing source can also be operated. For this operation, click

the Modify or Delete button on the upper left of the dialog box. Perform the procedure

described in the subsection 4.2.4.3 Procedure: Modify NE Timing Source or 4.2.4.4

Procedure: Delete NE Timing Source respectively.

In addition, the switching type can be set for each timing source in the Set Clock ExtraCommands dialog box, which will be opened by clicking the Switch button on the top

4.2.4.1 Items and Parameters

The Setup-Timing Source Configuration dialog box has the following items

and parameters:

ITEM/PARAMETER VALUES DESCRIPTION

System/Bypass Displays the system timing source and bypasstiming source. System clock is the workingclock for phase-lock loop of SDH system, andbypass clock is selected for external outputclock

Timing Source Displays the list of timing sources for

selection.

Receive SSM Set Value Select the QL (quality level) of the receiving

timing source from the drop-down list. This isvalid when the SSM protocol is selected.

Transmit SSM Mode Force/Auto Select Force or Auto from the drop-down list.

When Force is selected, the selected port willbe forced to send QL of the timing source.

When Auto is selected, the QL of the timingsource sent at the selected port is that of thecurrent operating reference clock. In this case,the current operating reference clock is not thetiming source of the selected port.

Force Transmit SSM

Mode

Selected port sends forcibly QL value of thetiming source.

Auto Reserved DNU

Group ID

0 thru 255 Value “0” means the Auto Reserved DNUGroup ID is invalid.

Hold off Time 0 thru 1800

(ms)

Set Hold-off time, which is the duration to holdQL until the operating timing source switchesto be available upon failure of this timingsource. The step is 300 ms.

WTR Time 0 thru 7200

(sec)

Set Wait To Restore time, which is the amountof time to wait before a recovered timingsource becomes active again. The step is 60s.

Priority 1 thru 256 Set the priority of timing source

manually. The highest priority is 1, and thelowest is 256.

4.2.6 Setup NE Clock Module Configuration

In the Setup-Timing Source Attributes dialog box, the timing source attributes are

specified for the NE clock module configuration.


The Setup-Timing Source Attributes dialog box has the following items and

parameters:


System/Bypass Select System or Bypass for timing source:

System: For NE system clock with PLL

Bypass: For EXTCLK output without PLLRecoverability (Check Box:

Revertive )

Specifies the recoverability for timingsource switching.

When Revertive is selected (with a tick):

When the timing source having higherpriority is once switched due to failure andit is recovered to normal condition (thefailure is cleared) after that, the currentactive timing source will then switch back tothe timing source having higher priorityagain.

When Revertive is not selected (the

check box is empty):Switching back to timing source havinghigher priority will not occur.

Switching Criterion Priority/SSM When Priority is selected, the clockmodule switches according to the priorityorder that is set manually for timingsources.

When SSM is selected, the clock moduletakes the QL that is set manually for timingsource and the actual QL value as theprecondition. When the QL that is setmanually and the QL collected by line

coexist, the former (QL set manually) iseffective. When the QLs of several timingsources are same, the clock moduleswitches according to the priority that is setmanually for timing source.
