Studer Call Management System Product Information

The Studer Call Management System uses Voice Over Internet Protocol technology to replace the physical Telephone Hybrids and Codecs. The control and signalling systems of the hybrids and codecs are integrated parts of CMS. It will interface to most PBX’s with VOIP interfaces, direct with ISDN lines or to the Internet. It also allows the control of analogue lines (POTS). When interfaced

with the Studer OnAir 3000 console platform, the result is better, more effective and intuitive handling of outside sources. The CMS has appli-cations for different situations where telephone and/or codecs are involved in a broadcaster’s daily work, ranging from simple off-air interviews to large game shows.

Foralongtimenow,ISDNhasbeentherelevantstandardformoderntelecommunication. Strong services and high quality of speech aresettingthebenchmarksforanycompetingtechnique.

Until now integrating VoIP meant difficulties in many respects: acomplex integration scenario, lessqualityof service, lowquality inspeech transmission. The simple reason for this is that ISDN cardsarenotcompatiblewithVoIP.Thereforeexpensivegatewayshadtobeinstalled,toallowexistingISDNapplicationsandhardwaretointegratetelephonesandotherequipmentdesignedfortheVoIPnet.
