14.1.1
Selecting the Host Reference Clock
Configure the clock reference for each host. Remotes automatically acquire a clock source
over optical fiber and do not require configuration in the EMS.
To select the reference clock:
1. Select the host in the system tree.
2. Click
to display the list of optical ports.
3. Select one of the following Clock Reference options:
Internal
: host is providing the clock signal (default for single host)
Optical
: host requires an optical clock signal from upstream source
External
: host requires an external clock signal
14.1.2
Verifying Clock Synchronization
If the reference clock is not properly configured, the RF signal between the host and
remotes cannot synchronize. The result is either an optical path failure alarm or an outage
condition.
Use the following rules to verify clock synchronization:
There can be only one master clock
A standalone clock source such as a GPS, base station, or third-party clock can be
used as a master clock
A host configured with
Internal
clock can be used as a master clock
A host configured with
External
must receive the reference clock from a
standalone clock source or from another hdHost PS
A host configured with
Optical
must receive the reference clock over optical fiber
from another upstream clock source
