MANUFACTURER: Custom Install


Requires SFP-5030-31 

The FRM220-FXO-FXS-SFP is a POTS (RJ11) port over fiber optic media converter. The PSTN two-wire POTS telephone port can be configured either as an FXO (PBX trunk) or FXS (telephone set/fax machine/dial-up modem) device just by a simple DIP switch setting. Using a pair of converters, a telephone line can be extended over a fiber optic circuit, providing full service and features like Caller ID. The converter can be used in service mode, allowing connection of 2 telephone sets in between. FRM220-FXO-FXS-SFP has an open SFP slot that accepts a 155Mbps rated SFP transceiver (SFP-5030-31). 

When the FRM220-FXO-FXS-SFP POTS over fiber converter is placed in the FRM220 rack with in-band and SNMP management, the converters status, type, version, fiber link status, POTS RJ11 port status and alarms can all be displayed. Configuration is also available to enable or disable the port, reset the port, do far end fault setting, and initiate local or far end loop-back tests. 

The uniqueness of FRM220-FXO-FXS series is given by the ability to convert from standalone media converter to card for the managed FRM220 chassis, in matter of minutes. In an always changing and growing networking environment, such a versatile feature allows network operators to switch to higher density and aggregation hubs without the need to purchase new fiber optic converters.
