Ethernet Traffic Interfaces
The front panel of the PTP 820G contains four electrical and two optical GbE Ethernet traffic interfaces:
•
2 x GbE dual mode electrical or cascading interfaces (RJ-45) – GbE1/CS1, GbE2/CS2
•
2 x GbE electrical interfaces (RJ-45) – GbE3, GbE4
•
2 x GbE optical interfaces (SFP) – SFP5, SFP6
GbE1/CS1 and GbE2/CS2 can be configured as normal GbE traffic interfaces or as cascading interfaces. When
operating in cascading mode, these interfaces can handle hybrid Ethernet and Native TDM traffic, enabling
operators to create links among multiple PTP 820G units in a node for multi-carrier and multi-directional
applications based on hybrid Ethernet and TDM (Native or pseudowire) services.
Ethernet Management Interfaces
PTP 820G contains two FE management interfaces, which connect to a single RJ-45 physical connector on the front
panel (MGMT).

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.
