Beskrivelse
Fra manualen:
The devices of the CENTAURI series are audio gateways; in other words they are audio codecs with extensive network ability (Internet, Intranet, LAN, WAN). They support all common coding procedures and transmission protocols
The CENTAURI 2001 and 3001 Audio Gateways have a display and a keyboard on the front of the device. You can therefore set up a connection to another communication partner immediately as soon as you have unpacked such a device and connected it up to the mains and ISDN.
