ConnectTrio combines the following in one half-rack/1RU device: two independent analog POTS telephone hybrids; an ISDN S0 interface with two independent ISDN B-channels; and two independent VoIP audio codecs. This not only saves rackspace and eliminates the need for additional equipment, but also provides enhanced flexibility to the intercom installation. Connect Trio enables you to dial, make and receive calls to and from any PSTN, VoIP, ISDN or mobile phone as well as G.722 reporter codecs. When used with Artist intercom systems you can even remote control panels via ISDN.
