FIELD: optical communications.
SUBSTANCE: first, administrative information of subnet device, made by manufacturer, who is not SDH devices manufacturer, included in base net, in given area of structure of frame of synchronous transfer mode (STM-N), and then said structure of frame STM-N is sent to base net device, connected to noted subnet, with following transfer of frame structure through said base net into device of destination subnet. Using this method, administrative information of SDH devices of multiple manufacturers can be conveyed while using code-independent transfer mode through SDH devices of certain manufacturer.
EFFECT: higher reliability.
