FRM220-FXO-4/FXS-4 are 4 channel POTS (Plain Old Telephone System) over fibre converter/extender. The four POTS connection uses standard RJ11C modular connectors for each copper pair connection. A pair of FRM220-FXO-4/FXS-4 is required to implement an end to end system. FXO type unit connects to a telephone line (PSTN) or PBX station line and has the ability to detect ringing voltages and to act as a telephone. FXS type unit is the reciprocal unit and has the ability to act as PSTN and connects to a telephone device. Two FXS cards may be connected back-to-back to provide a private "hotline". When the FRM220-FXO-4/FXS-4 cards are placed in the FRM220 rack with SNMP management, in-band management allows configuring and viewing the card and remote converter's status, type, version, fibre link status, on-hook status and alarms.
