Inter-IDU Protection Connectivity and Management
PTP 820G units in a redundancy configuration must have their CPUs interconnected in order to
synchronize their protection status. The same IP address is used for both PTP 820G units, to ensure
that management is not lost in the event of switchover. A special cable is required to enable this
connectivity.

PTP820G Splitter cable for protection and management,
1.34m,CAT5E
The protection and management splitter cable must be connected to the management interfaces of
the two PTP 820G units using the RJ-45 plug-ends. The third end of the protection splitter cable
(RJ-45 socket) is connected to an external management station.
