Configuration options
This section describes three different ways in which PTP-SYNC and its timing reference
source may be configured.
Single link configuration
Use the single link configuration where a site contains only one TDD master ODU. Each
link requires one PTP-SYNC unit connected to the master ODU and one compatible GPS
receiver. The GPS receiver and LPU can be replaced by an alternative compatible 1 Hz
timing reference.
