Figure 2 GbE Combo Interface Numbering

Note
When using electrical ports GbE 1 through GbE 4 to connect between the PTP 820F IDU
and an outdoor unit such as PTP 820C or PTP 820S, in areas in which severe lightning
conditions are likely to occur, it is required to use lightning protection.
GbE 1/SFP 1 and GbE 2/SFP 2 can be configured as normal Ethernet 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 820 units in
a node for multi-directional applications based on hybrid Ethernet and Native or pseudowire TDM
services.
In addition, two pairs of electrical and optical interfaces towards the right of the front panel can be
used to provide either two Ethernet interfaces or one Ethernet interface and one radio interface:
• RFU3/SFP5 and RFU3/2.5GE5 – A combo interface that can be used as either an SFP or RJ-45
RFU interface or an SFP or RJ-45 Ethernet interface.
• SFP6/2.5GE6 - A combo interface (SFP or RJ-45) for Ethernet.

Ethernet Management Interfaces

PTP 820F contains two FE management interfaces, which connect to a single RJ-45 physical
connector on the front panel. The RJ-45 connector is the upper RJ 45 interface in a pair of
interfaces labeled MGMT/SYNC.
