The FRM2-BRI/ST2 is an ISDN over fibre modem that enables basic rate ISDN interfaces to be extended over multimode fibre optic cabling. The units are ideal for sensitive data applications that require the use of fibre and have been designed to transport a single ISDN Bri interface over multimode fibre optic cabling. The unit is completely transparent to all ISDN protocols and is simply 'inserted' between the ISDN line and end terminal equipment.
The FRM220-FXS/FXO Fibre Optic Modem allows the extension of a single analog telephony service over fibre cabling. The unit can be employed as a fibre optic telephone extender but can also be used to connect to any analog device that uses the 'voiceband' such as fax machines. analog dial-up modems and EPOS terminals.
FRM220-FXO/FXS-4 is a 4 channel POTS (Plain Old Telephone System) over fibre converter/extender. The four POTS connection uses a standard RJ-11C modular connectors for each copper pair connection. A pair of FRM220-FXO/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. When the FRM220-FXO/FXS-4 card is 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.
