Overview
E-link 24 channel POTS (Plain Old Telephone System) phone lines
over fiber converter / extender. This Voice over Fiber converter
uses RJ-11C modular connectors for each copper pair connection. FXO
type unit connects to a telephone line (PSTN) or PBX station line
and has ability to detect ringing voltages and to act as a
telephone. FXS type unit is the reciprocal unit and has ability to
act as PSTN and connects to a telephone device.
