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 can be replaced by an alternative compatible 1 Hz
timing reference (Figure 2-9).
Th
e wireless
configuration settings are:
Master Slave Mode = ‘Master’.
TDD Sync Device = ‘PTPSYNC’.
Cluster Master Slave = ‘Cluster Master’.
PTP Sync Site Reference = ‘GPS/1PPS External’.
