PTP-SYNC unit
PTP-SYNC unit description
The PTP-SYNC unit (Figure 29) is an optional component. It is required when TDD
synchronization is implemented using PTP-SYNC. It measures the difference between the TDD
frame timing and a 1 Hz timing reference, and signals this time difference to the ODU. For more
information on this feature, refer to TDD synchronization on page 1-17.
The PTP-SYNC unit is powered using standard power-over-Ethernet from the PSU. One PTP-
SYNC unit is required for each synchronized link.
The PTP-SYNC unit is a compact indoor unit mounted on a wall, shelf or (using an optional rack
mounting adaptor) in a standard 19 inch rack (Figure 30).
