Connector Description
POTS connector For O-24121G-A and O-24120G-A outdoor ONTs, the POTS interface is an
48 position RJ-21 connector that supports up to 24 POTS lines. The cable
can be attached to an external customer patch panel or to an IDC block,
punchdown block, or screw terminal block within an enclosure.
10/100/1000BASE-T
Ethernet connectors
For O-24121G-A and O-24120G-A outdoor ONTs, the 10/100/1000BASE-T
Ethernet interface are two 48 position MRJ-21 connectors that support
up to 12 10/100/1000BASE-T Ethernet lines.
See the Planning and Ordering Guide for more information about
ordering MRJ-21 Ethernet cables. These cables must be ordered
separately.
SWRD The SWRD has two 10/100 Ethernet ports and 2 RF ports. The SWRD is
powered from the ONT by an Ethernet cable once the SWRD is installed
and an Ethernet UNI is provisioned. The SWRD is separately orderable.
Power and alarm
connector
A 7-pin Phoenix connector provides the 48 V input power and return for
the LP MDU ONT and the UPS alarms.
Separate power and alarm cables are required for class 1 wiring. When
wiring the LP MDU to a UPS, use a class 1 powering cable. In that case,
the combined power/alarm cable is only used for alarm wiring, not for
power wiring. A separate 16 AWG wire wrapped in a sleeve is required.
Auxiliary environmental
alarm connector
A 7-pin Phoenix connector provides up to three customer defined
environmental alarms for the LP MDU ONT.
Craft port The craft interface is a right angled RS232 serial port that can be
accessed with a male DB-9 connector.
Fiber optic connector An SC/APC fiber optic connector terminates a fiber optic connection
from the P-OLT.
Ethernet port This connection is provided through Ethernet RJ-45. The RJ-45
connectors support 10/100BASE-T or 10/100/1000BASE-T Ethernet
connections.
Video coaxial connector This connection supports RF video on all of the LP MDU ONTs except for
the 3FE 51185 AB variant of the O-24121G-A and O-24120G-A outdoor
ONT.
