Cluster with PTP-SYNC and no GPS receiver
Each link requires one PTP-SYNC unit. PTP-SYNC units are connected together in a
daisy-chain. Between two and ten PTP-SYNCs may be chained in this way. 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
(
Figure 2-15
).
The wireless configuration settings are:
•
Master Slave Mode = ‘Master’ (all ODUs in cluster).
•
TDD Sync Device = ‘PTPSYNC’ (all ODUs in cluster).
•
Cluster Master Slave = ‘Cluster Master’ (first ODU) and ‘Cluster Slave’ (others).
•
PTP Sync Site Reference = ‘Internal’ (all ODUs in cluster).
