Description

F-4TEL RJ11 to Fiber Optic Telephone Media Converter

The F-4TEL is used for carrying four phone lines over fiber optic cable.  Telephone over Fiber applications offer a secure connection that is impossible to bug.  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 these devices, four independent telephone lines can be extended over a fiber link.  The F-4TEL provides full service for features like caller ID.  The converter can be used in service mode, allowing connection of 2 telephone sets.  The unit offers SNMP allowing remote management and sensing of converter status, type, version, fiber link status, RJ11 port status, and alarms.  The F-4TEL is a simple and reliable solution for data carriers and service providers for Telephone over Fiber links.
