port fails, the standby port is activated and assumes the role of "active" as long as it is
in normal state. If the latter fails, ports will be switched again. This switching can
continue any number of times, without any preference of a specific port.
Automatic (Auto Revert) - in this mode, the selected port (as defined in Selected Port)
is always preferred over the other port. In case that the selected port fails, the
standby port is automatically activated. Once the selected port is fixed, the NSG
automatically switches back to the selected port.
5. To select the active DTI port, open the Selected Port list and select either port 1 or 2.
NOTE: The Selected Port list is disabled if Automatic (no Auto Revert) is selected.
6. In Notification, define which notification to send once the status of the DTI client changes:
Log Status Change Events - send a notification to the alarm log upon a change in the
status of the DTI client
Send Trap on Status Change - send an SNMP trap upon a change in the status of the
DTI client
3.11.2 Viewing DTI Client and DTI Port Information
1. Select the Platform > General tab.
2. In the In Back Panel View, select the DTI component.
NOTE: The DTI section is enabled only when a DTI client is installed in the device.
The General tab appears.
3. To view DTI client information, focus on Client Information section.

Explanation
Local oscillator has not yet stabilized
DTI client is not locked to the signal of the DTI server, and is running
freely using its own internal real-time clock. Freerun indicates that since
its last initialization, the client was not locked to the server.
DTI client is locked to the DTI server, working normally
This is a transient state, which may last up to 2 seconds. It indicates that
the DTI client has experienced a momentary interruption in its timing
signal, but is still able to maintain acceptable timing. NSG 9000 is still
locked to the DTI server clock.
DTI client lost its sync to the DTI server clock. Working in "best effort
mode", with the last known valid time correction
The DTI client has just acquired a valid signal, and is in the process of
locking to it. If this status is displayed for a prolonged time, this
indicates a problem with the received DTI signal or with the DTI client.
In 10Mhz Ref., indicates whether the 10Mhz Reference signal is present.
