Sync Input
This section describes synchronization options for PMP and PTP configuration.
Figure 19 Sync Setting configuration
The Sync Input parameter can be configured under Sync Setting tab of Configure > General page (see
General configuration on page 1-72 ).
PMP/PTP 450i Series has following synchronization input options:
• AutoSync
• Au Free Run
• Generate Sync
AutoSync
For 450i AP/BHM and 450m AP, the AP/BHM automatically receives sync from one of the following
sources:
•
GPS Sync over Timing Port (UGPS, cnPulse, co-located AP GPS sync output, or “Remote” Device
feed from a registered SM’s GPS sync output)
•
GPS Sync over Power Port (CMM4), CMM5, cnPulse module ODU Sync Port.
For 450 AP, the internal GPS is available in addition to the above sync sources. For a 450 BHM the only
available sync source is the Timing Port, as GPS Sync Over Power Port is not supported. For a 450b BHM
only GPS Sync Over Power Port is available.
Upon AP/BHM power on with the Free Run Before GPS Sync parameter set to disabled, the AP/BHM
does not transmit until a valid synchronization pulse is received from one of the sources above. If there is
a loss of GPS synchronization pulse after sync is initially established, within two seconds the AP/BHM
automatically attempts to source GPS signaling from another source.
