Intelligent and seamless interfacing to the outside world is the key to success in many intercom applications. Riedel offers diverse interface solutions for the seamless integration of radios, telephones, ISDN, digital as well as analogue party-lines, audio routers or Audio-over-IP.

Connect Duo interfaces your intercom system to ISDN (European protocol) and PSTN public telephone networks. It combines an ISDN S0 interface and an analogue POTS telephone hybrid in one halfrack/1RU device and enables you to dial, make and receive calls to and from any PSTN, ISDN or mobile phone as well as G.722 reporter codecs. Since the unit can transmit and receive two separate audio channels over one single S0 interface it allows connections to two separate destinations to be established. When used with Artist intercom systems you can even remotely control panels via ISDN.

Connect IP provides high quality audio-over-IP interfacing for intercom systems. The 19”/1RU unit allows for matrix-to-matrix connections and matrix-to-control panel connections as well as for the distribution of audio lines over IP. The interface converts one AES3-stream into compressed IP data and vice versa. Connect IP can be configured to your individual bandwidth needs, always providing an unmatched combination of audio quality and low network traffic. The device supports remote user control key-panels with full functionality.

The 19“/1 RU 4-channel 2/4-wire interface IF-2104 converts four partyline channels to transformer balanced audio inputs and outputs (4-wire) on individual XLR-connectors. The 2/4-wire hybrid features automatic nulling. The interface detects the S-CALL and switches built in relays to activate paging systems, radio equipment or other external devices.

The RiFace is a universal radio interface to connect wired communication systems with walkie-talkie radio systems. The 19”/2RU interface includes one or two two-way radios (user provided), processor logic to control the radios as well as circuitry to adjust the levels of the various audio sources. Set-up and operation is fast and easy.

The PMX-Series panel multiplexers are used to remote up to four (PMX-2008: eight) intercom panels from the Artist matrix using a fibre link. Depending on the SFP modul (SM/MM) the system allows operation of a group of intercom panels over a distance of up to 500 m (1,600 ft) or 2 km (1.2 miles) in a cost-effective way while reducing setup time to a minimum.

The RIF-2064 is an external GPI interface designed for the Artist digital intercom platform providing 64 GPI/Os. Along with offering greater cost-effectiveness, RIF-2064 presents increased efficiency when used as a remote GPI-interface; a considerable amount of cabling and installation costs are reduced by picking up or sending GPI-signals at the location where they occur.
