The ORBAN OPTICODEC 7600, designed and engineered by our German engineering team in Ludwigsburg, is the next step forward in audio transmission using ISDN - X.21 - V.35 and TCP/IP. The ORBAN OPTICODEC 7600 is the natural successor of one of the most used codecs the MusicTAXI. The OPTICODEC 7600 is an extremely powerful codec using the latest MOTOROLA DSP (we do not use PC processors). With our unique AUTOMATIC CODEC DETECT function, you do not have to worry about what codec is on the other side.
