Cabling Requirements for Unit Redundancy
Cabling for Ethernet Interfaces
For Ethernet Splitter Mode, the following Y-cable must be connected to the relevant interfaces on the active and
standby units:

Description
C000082L153A
PTP 820G Fast Ethernet Protection Y-cable, 1.34m, Cat5E
No special cabling is required for other Ethernet protection modes.
Cabling for E1/DS1 Interfaces
If the E1/DS1 interfaces are being used, a Y-cable is used to connect the active and standby E1/DS1 interfaces. The
following table shows the Part Number and Marketing Model of the Y-cable required for E1/DS1 protection.

PTP 820G TDM Protecftion Y cable, 0.6m,120 ohm
Cabling for T3 Synchronization
If T3 synchronization input is being used, a Y cable is used to connect to the active and standby Sync interfaces.
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.
