Intercommunication of Asterisk and VCON VoIP PBX
Balon, Jiří ; Říha, Kamil (referee) ; Číka, Petr (advisor)
The main goal of this bachelor thesis was to familiarize with VoIP telephony development and its nowadays utilization. First part of the work includes description of known communication protocols SIP and H.323 architecture and their usage in communication. Next part is dedicated to software PBX Asterisk that runs under Ubuntu distribution of Linux operation system. The process of PBX installation is described there as well as its adjustment for SIP and H.323 for communication within IP net. There is also described software PBX VCON that runs under Windows XP operation system. Beyond the adjustment of the PBXs there is also concrete adjustment of software clients SJPhone and X-Lite that are necessary for communication between individual telephone exchanges. The final chapter is dedicated to the problems of mutual connection (intercommunication) of individual telephone exchanges Asterisk and VCON.
Measuring methods of key parameters in optical networks
Balon, Jiří ; Reichert, Pavel (referee) ; Tejkal, Vladimír (advisor)
The main goal of the master’s thesis was to familiarize with optical networks dilemma and its measuring during fabrication. The whole thesis is divided into several parts where the first part deals with optic fiber dilemma. It describes its kinds, properties and also suggests a basic principle of optic signal dispersion using these fibers. It describes also optical network FTTx architecture (Fiber To The x). The second part of the thesis focuses on methods of measuring key parameters of optical networks. Is brings out the methods of measuring optical loss and dispersive influences. The last and final part in focused on creating a methodical manual for measuring these networks during its fabrication and verifying measuring methods stated in the theoretical part inside a real network. Measuring was implemented on an optical network of Masaryk University in Brno.
