14 TDD Synchronization Configuration and Installation
Guide
Configure Link Range: Choose "yes" to enter the range of the link in control below: Note
that Link Range MUST be less or equal to "Longest Link in Network". In some networks,
throughput can be increased by entering the exact range of each link in the wizard.
TDD Holdover Mode: Two values: "Strict" and "Best Effort". If a PTP 600 master ODU is
configured for a TDD Holdover Mode set to "Strict", then it will not transmit when
synchronization is lost. On the other hand, a link configured for TDD Holdover Mode set to
"Best Effort" will synchronize when a reference signal is available, but will otherwise use best
efforts to operate in unsynchronized fashion.

CAUTION: the values entered for the controls in Figure 149 MUST be the same for
master/slave pairs for all the links in the network, except for the attribute "Range of This Link"
which can be entered exactly for better performance.
