Configuring NetRef Settings (CTPView)

NetRef primary backup operation involves a new packet flow from the primary node to

all the backup nodes. These timing packets are sent at a rate of approximately 4.5 packets

per second.

NOTE: In this topic, the terms Primary and Backup refer to master and slave

operations or nodes, respectively.

To configure network node reference with primary and backup operation using the Node

Configuration page of CTPView:

1. In the side pane, select Node > Node Config.

2. Configure the parameters described in Table 55 on page 128 and click Submit

Configuration.

3. (Optional) Click Node > Node Query to verify the NetRef master and backup node

configuration details.

Your ActionFunctionField

Select Yes or No to enable or disable the

master node to function as the reference clock.

Specifies whether you want to enable or disable the

NetRef master node to function as the reference port

providing frequency for clock synchronization.

You need to specify this value for the 1st Priority

Reference 0, 2nd Priority Reference 1, 3rd Priority

Reference 2, 4th Priority Reference 3, and 5th Priority

Reference 4 fields to specify the reference clocks for

the master nodes with corresponding priorities.

Port Providing

Reference

Select a reference frequency in the range from

32 Khz through 4096 KHz.

You can configure the CTP systems by using

the menu interface to provide multiple

prioritized node clock references. An external

reference input and any of the serial interfaces

may be used for the node reference clock.

Reference frequencies must be 32 KHz, n x 64

KHz, or 1,544 KHz up to a maximum of 4096

KHz (2048 KHz maximum on the CTP1002).

Specifies the frequency to be used for the reference

clock or the master node.

You need to specify this value for the 1st Priority

Reference 0, 2nd Priority Reference 1, 3rd Priority

Reference 2, 4th Priority Reference 3, and 5th Priority

Reference 4 fields to specify the reference clocks for

the master nodes with corresponding priorities.

Select the slave node to be locked to the

different master nodes.

Specifies the slave node for which multiple master

nodes are associated for receiving clock synchronization

information.

NetRef: Slave

Enter the IP address of the master node with

priority 1.

Specifies the IP address of the master node with priority
