Modelling of Autostart for an AXE 10 Extension Module Group
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
The purpose of this paper is to investigate how an autostart function for an Extension Module Group should work. An Extension Module Group is a distributed part of the AXE 10 computer controlled digital telecommunications exchange. The autostart function would avoid the need to send technicians to start/start-up new or failed equipment.
Two of the most important components in the Extension Module Group are the Extension Module Regional Processor and the Signalling Terminal Remote. The Extension Regional Processor handles the decision making in the Extension Module Group and the Signalling Terminal Remote administers the communication with the exchange.
The Autostart function should restart/start-up (i.e. boot) Extension Module Regional Processors and Signalling Terminal Remotes after failed recovery attempts, after repair and after installation. Since there are three different cases the autostart function should be divided into three different functions. They might be called AUTOREC, AUTOREP, and AUTOINST. The three functions will be invoked by the main function called AUTOCENT.
