FIELD: radio engineering, communication.SUBSTANCE: in synchronising method communication organisation is made in several hierarchically organised levels with synchronising the nodes of lower level to higher level; subordinate node can have nodes subordinate to it, for which it is superior: each communication centre has its assigned time interval for receiving and transmitting; the exchange between superior and subordinate nodes is made in repeatable frame, during which there performed is the exchange with all subordinate nodes: time intervals of transmitting and receiving are preliminary distributed in frames of each network level. Multi-level communication network has several hierarchically organised levels with synchronising the nodes of lower level to higher level; subordinate node has nodes subordinate to it, for which it is superior. Network node has physical interface device, medium access device, interface device that consists of n (n?1) interfaces that are connected to n terminating devices correspondingly.EFFECT: extension of functional capabilities due to increase of efficiency of frequency resource use at guaranteed band pass for each subscriber, increase of communication system failure tolerance, including deliberate ones.17 cl, 7 dwg |
