Overview

FRM220-FXO-4/FXS-4 are 4 channel POTS (Plain Old Telephone System) over fibre converter/extender. The four POTS connection uses standard RJ-11C 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 units connect to a telephone line (PSTN) or PBX station line and has ability to detect ringing voltages and to act as a telephone. FXS units are the reciprocal and have 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 "hot line".

Management

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.When placed in a single slot chassis and used standalone without management, the card may be configured by DIP switch.

The FRM220-FXO/FXS & FRM220-FXO/FXS-S provide audio transmission, caller ID, ringing at the distant end and automatic ring down. Two units are required to implement an end to end system. The RJ-11 connector provides the electrical interface between the media converter and the telephone device or PSTN.
