DSCP

Enter the Differential Service (DiffServ) value for the IP packet.

Note: This should be configured to Explicit Forward (EF) which is a value of 46 decimal.

Announce Start Timeout

Allows you to enter a value within the range of 0 through 120 minutes to delay the transmission of announce messages.

On rebooting, the TCA Timing Server starts transmitting the announce messages for the synchronization source selection if any one of the following condition is satisfied:

• After the expiry of the configured timeout value
• Any configured synchronization source is locked to the frequency within the configured timeout value

When you set the value as 0 (default value), the transmission delay feature is disabled.

Note:

• The transmission delay feature is applicable only to the first lock state of any synchronization source.
• The configured timeout value is effective on next reboot.

Announce Range

Select the range for announce interval message rate. The available options are:

• 1 packet/1 sec
• 1 packet/2 sec
• 1 packet/4 sec
• 1 packet/8 sec

Note: It is recommended that the range be set for the full range support (that is, minimum = 1 packet/1 sec and maximum = 1 packet/8 sec).
