Planning synchronized networks

Using PTP LINKPlanner for synchronized networks

TDD synchronization should be planned using LINKPlanner. This will provide the
necessary TDD Frame parameter values which are required to complete a
synchronized installation. Please refer to the

TDD synchronization configuration options

The PTP 600 supports the following TDD synchronization configurations:
•
Standalone with UltraSync
receiver connected at the master ODU. Use this configuration only for legacy
applications.
•
Standalone with PTP SYNC
connected to the master ODU and one compatibles 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.
•
Cluster with PTP SYNC and GPS receiver
PTP SYNC unit. Each site requires one compatible GPS receiver. Collocated PTP
SYNC units are connected together in a daisy-chain. Use this configuration
where a site contains collocated TDD master ODUs in an extended network
where TDD master ODUs are located at multiple sites.
•
Cluster with PTP SYNC and no GPS receiver
PTP SYNC unit. PTP SYNC units are connected together in a daisy-chain. One
ODU is designated as a cluster timing master. Use this configuration where all
master ODUs are collocated at a single site. As this configuration does not
require a GPS receiver, it provides additional flexibility, particularly in
applications requiring rapid deployment.
NOTE
2-12
If PTP-SYNC is the selected TDD synchronization method, select a 1 Hz
timing reference for the system. This will normally be a GPS receiver
module.
