Abstract [en]

The purpose of this thesis work was to examine the possibility to implement a common addressing algorithm in the digital CAS trunk line programs used at the call setup in an originating exchange. The algorithm formed is described in an SDL-flow and in PLEX-M software code. As result of the thesis work, the addressing parts in some of the trunk line programs was replaced by the designed common algorithm and successfully verified in target machine in MD-laboratory. The amount of code was reduced in all of the tested trunk line programs.

Abstract [sv]

Syftet med detta examensarbetet var att undersöka möjligheterna att skapa en gemensam adresseringsalgoritm för de digitala CAS trunkprogrammen som används vid uppkoppling av utgående samtal i en växel. Adresseringsalgoritmen är beskriven med SDL-flödesschema och i programspråket PLEX-M. Resultatet av examensarbetet blev att adresseringsbiten i några av trunkprogrammen ersattes med den gemensamma algoritmen och framgångsrikt verifierades i MD-labbet. Mängden kod minskade i alla de trunkprogram som testades.
