RICi-4E1/T1, RICi-8E1/T1 Ver. 2.0 Configuring for Operation 4-11
It is recommended to apply different settings to the master clock and the fallback
clock, for example Rx Clock for the master clock and Internal for the fallback
clock.
³ To select the clock sources:
1. Navigate to Main Menu > Configuration > System > Clock Source > Master
Clock.
The Master Clock Source menu appears.
2. Press <1> to toggle the first-priority clock options:
Internal, if you want the master clock to be the unit’s internal clock.
Rx Clock, if you want the master clock to be the clock for a specific E1/T1
link.
3. If you have chosen Rx Clock, specify the port to be used, E1/T1 Port 1..4 or 8.
4. Select Save.
The master clock source settings are saved.
5. Return to the Clock Source menu (Main Menu > Configuration > System >
Clock Source) and select Fallback Clock.
The Fallback Clock Source menu appears.
6. Press <1> to toggle the second-priority clock options:
Internal, if you want the fallback clock to be the internal clock of the
relevant unit.
Rx Clock, if you want to set the fallback clock to refer to a specific E1/T1
link.
7. If you have chosen Rx Clock, specify the port to be used: E1/T1 Port 1..4 or 8.
8. Select Save.
Configuring Fault Propagation
When Network - > User fault propagation is enabled, the LAN ports are closed
whenever the MLPPP uplink becomes inactive.
When User - > Network fault propagation is enabled, the following two
configuration modes are available:
• Interface Deactivation. The MLPPP will be deactivated whenever an
administratively enabled LAN port is closed.
• OAM Signaling. Applying an 802.3ah OAM mechanism, all administratively
enabled LAN ports in the peer device are closed if one of the local device’s
administratively enabled LAN ports is closed while the MLPPP remains active.
One of the Ethernet ports remains unaffected, in order to leave a
management channel open.
This applies to #4 in four copper devices and to #2 in 2 copper and 2 SFP
devices.
