Abstract
RADIOKOMUNIKACIONI SISTEM, naznačen time, što su na svakom delu trase primopredajne stanice (F1-F8) povezane medjusobno i sa centralnom preko četiri para optičkih vodova (a1, b1, a2, b2, a3, b3, a4, b4) tako da su po dužini naizmenično spojene za različit par vodova koji su spojeni na predajnike (5) i prijemnike (E) centrale koja je spojena na integrisani sistem za prenos podataka (ISDN).
