Planning for Receive Diversity
PTP 800 supports the Receive Diversity feature, which provides hitless protection against
receiver faults. This feature can be enabled (at the CMU) in any of the supported 1+1 Hot
Standby configurations described in Antenna, RFU and CMU configurations for 1+1 on
page 2-35.
This feature provides Receive Spatial Diversity when two antennas are installed at the
same end, that is, in the following configurations:
• ODUs with separate direct mount antennas on page 2-38
• ODUs with separate remote mount antennas on page 2-39
• IRFU 1+1 Tx MHSB / Rx SD with two remote mount antennas on page 2-41
For further information on the Receive Diversity feature, see Receive Diversity on page 1-
