See Figure 16 for the location of the SC/APC connector compartment with the optical fiber plugged into
the connector.

Remove the dust cap from the connector and connect the EPON fiber cable to the ONT. The connector is
keyed to prevent mis-insertion into the port. The dust cap should always be left on the connector when
the fiber is not connected to the equipment.
5.
Connect the opposite end of the EPON fiber to the wall service connector, which may be similar to that
shown in Figure 13 Typical Wall Plate Example.

You can also instead connect the EPON fiber that was wrapped in a fiber tray to the ONT. See an ex-
ample in Figure 12 Snapping the ONT onto the Fiber Tray.

Connecting Telephones to the EPON Multi-service Gateway ONT
The ONT-2-E4020i, ONT-2-E4021i, ONT-2-E4020iWn, and ONT-2-E4021iWn provide two 6-pin modular
RJ-11 jacks for connecting standard premises telephones. These voice ports each support a REN (Ringer
Equivalency Number) of 4, and a maximum line length of up to 152.4 meters or 500 feet. The Ringer
Equivalency Number is the allowable load for all analog telephony devices (telephones, fax machines, mo-
dems, etc.) on the same incoming line.
The REN value controls the ringer (ringing) of telephones. A ringer equivalency number of 1 represents the
loading effect of a single "traditional" telephone ringing circuit, such as that within the Western Electric Model
500 telephone. Note that the REN of modern telephone equipment may be significantly lower than 1: as a
rough guide, externally-powered digital-ring phones may have a REN as low as 0.1, while modern analog-ring
phones (where the ringer is powered from the phone line) typically have a REN around 0.8.
The REN is indicated on an FCC-Compliance label affixed to the telephony device, and, in the case of internal
modems, generally is indicated in the user documentation.
