FRM220-FXO-4 - Four POTS (RJ11) FXO telephone lines over fiber multiplexer, SFP slot

FRM220-FXO-4 is a 4 channel POTS (Plain Old Telephone System) over fiber converter/extender. The four POTS interface uses a standard RJ-11C modular connector for each copper pair line. A pair of FRM220-FXO-4 and FRM220-FXS-4 is required to implement an end to end system. FXO mode connects to a telephone line (PSTN) or PBX station line and has ability to detect ringing voltages and to act as a telephone. FXS mode is the reciprocal unit and has ability to act as PSTN and connects to a telephone device. The small multiplexer offers great flexibility on the fiber port by adopting the widely used industry standard Fast Ethernet 155M rated SFP transceiver with both the FRM220-FXO-4 and FRM220-FXS-4 models. When the FRM220-FXO-4 card is placed in the FRM220 chassis with SNMP management, in-band management allows configuring and viewing the card and remote converter's status, type, version, fiber link status, on hook status and alarms. When placed in a single slot chassis and used standalone without management, the card may be configured by DIP switch.
