Single link configuration with PTP-SYNC
Each link requires one PTP-SYNC unit connected to the master ODU and one
compatible GPS receiver. Use this configuration where a site contains only one TDD
master ODU. The GPS receiver and LPU can be replaced by an alternative compatible
1 Hz timing reference (
Figure 2-13
).
The wireless configuration settings are:
•
Master Slave Mode = ‘Master’.
•
TDD Sync Device = ‘PTPSYNC’.
•
Cluster Master Slave = ‘Cluster Master’.
•
PTP Sync Site Reference = ‘GPS/1PPS External’.
