ISDN over Fibre
ISDN Bri Fibre Optic Modem
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.
POTS Analog Voice Fibre Optic Modem
FRM220-FXO / FXS 2-wire Fibre Converter
The FRM220-FXO/FXS POTS phone line converter extender is used to connect PSTN voice signals to distant Plain Old Telephone (POTS) devices. FRM220-FXO/FXS provides a fibre media transport for POTS transmission and features an RJ-11C for copper connection. A pair of FRM220-FXO/FXS is required to implement an end to end system. FXO mode connects to a telephone line or PBX 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 card is placed in the FRM220 rack with SNMP management, in-band management allows viewing the card and remote converters status, type, version, fibre link status, on hook status and alarms. Both card and remote can be configured to enable or disable the port, reset the port and set the FXO or FXS mode. FRM220-FXO/FXS-4 POTS Converter
FRM220-FXO/FXS-4 POTS Converter
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. |
