Management Interface Cable Options
If the user only needs to use a single management interface, a standard Cat5 RJ-45 cable (straight
or cross) can be connected to the MGMT interface.
To access both management interfaces, a special 2 x FE splitter cable can be ordered from
Cambium.

Description
N000082L122A
PTP 820G Ethernet split cable for Management
E1/DS1 Interface
PTP 820F includes an MDR69 connector in which 16 E1 interfaces are available (ports 1 through 16).
STM-1/OC-3 Interfaces
The PTP 820F includes two ch-STM-1/OC-3 ports, which can be used as a 1+1 STM-1/OC-3 protection
configuration. The STM-1/OC-3 port provides an interface for up to 63 E1 or 84 DS1 lines inside a
standard channelized STM-1 or OC-3 signal. Each E1/DS1 line is transported by a VC-12 container,
which behaves like a regular line interface.
Radio Interfaces
PTP 820F includes two combo radio interfaces (RJ-45 or SFP, RFU1 and RFU2). A third interface can
also be used as a combo radio interface (RJ-45 or SFP, RFU3).
Note
STM-1/OC-3 requires the addition of an optional rear-mounted STM-1/OC-3 module, which
is planned for future release.
