OPTICAL ELECTRONIC DEVICE FOR TRANSFERRING DISCONTINUOUS SIGNALS INTO COMMUNICATION LINE Russian patent published in 2007 - IPC H04L25/18 

FIELD: electric communications, in particular, engineering of devices which ensure synchronized operation of transmitters of discontinuous information of end devices of documental electric communications with physical communication lines.

SUBSTANCE: in accordance to the invention introduced are resistor, diode, two optical electronic relays, three buffer keys, four RS-triggers, two AND elements, OR element, XOR element, starting setting element, setting impulses generator and command selection block, with appropriate structure of connections, resulting in creation of a universal adaptive device for transmitting discontinuous signals, operation mode of which (unipolar or bipolar) is determined by code commands of transmitter. Device is efficiently protected from emergency load conditions and ensures indications of such conditions. Also, operation algorithm realized in the device allows to prevent unsanctioned transmission of discontinuous signals into communication line with simultaneously increased reliability of protection of transferred information from its leaks through physical circuits. Depending on operational requirements, optimal realization variants are suggested for certain components and units of the device.

EFFECT: reduced readiness time of device, expanded functional capabilities of device, increased reliability of operation in emergency situations and increased trustworthiness of control.
