Chapter 3: System planning Configuration options for TDD synchronization
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
49).
The wireless configuration settings are:
Master Slave Mode =

.
TDD Sync Device =
PTPSYNC

Cluster Master Slave =

.
PTP Sync Site Reference =
