U radu je opisan uticaj promene intervala detekcije na kriterijume verodostojnosti rada detektora neispravnosti u telefonskoj mreži elektroprivrede. Predložen je postupak za pronalaženje optimalnog intervala detekcije, i na osnovu njegovog sprovođenja dobijeni su optimalni intervali detekcije za tri slučaja prenosnih puteva višeg i nižeg prioriteta. Rezultati su predstavljeni u obliku grafikona, čijim korišćenjem se za unapred poznate saobraćajne karakteristike sistema pronalazi optimalna dužina intervala detekcije.

New modern technologies in mobile telephony overcome the possibilities of GSM systems. VAMOS technique is one way to improve traffic properties of traditional GSM systems. Our aim is to analyze the level of this improvement achieved by VAMOS implementation. The number of traffic resources is doubled, but it is proved that traffic capacity is more than doubled for full rate connections implementation and more than quadrupled for half rate connections regardless of offered traffic for all values of emission power difference between 4dB and 10dB when considering two paired subchannels. There are two loss types in VAMOS systems: unpairing loss and traffic loss when all subchannels are busy. The values of these two loss types whose sum presents the total loss in VAMOS systems are determined by originally developed simulation program. The achievable total loss may be decreased for 45% or even more when allowable power difference between paired channels is increased from 4dB to 10dB.
