SYSTEM FOR AUTOMATIC MONITORING OF ACCESS DEVICES OF STILLS AND METHOD OF OPERATION OF THIS SYSTEM Russian patent published in 2022 - IPC B61L27/00 H04M3/56 

FIELD: monitoring access devices.

SUBSTANCE: invention relates to means for monitoring access devices. The system includes two terminal stations A and B, 1+n blocks of the access device of the stage and a fiber-optic communication line. Each terminal station contains a block of automated workstation with installed monitoring and administration system MAS-PSD-3 and a station access device block, which contains an L3 Ethernet switch block, a switching station block and 1+n blocks of SFP modules located in the Ethernet- L3 switch, each of which transmits at its own wavelength and a CWDM multiplexer/demultiplexer unit. Each block of the distillation access device contains a pair of blocks of Ethernet switches L3, two blocks of the SFP module, a power supply block, a block of intercom, a block of optical switches OP installed in the gap between the outputs of the OADM block and the SFP module block. The system further comprises 1+n wavelength division multiplex OADM blocks, the number of which is always equal to the number of haul access device blocks.

EFFECT: expansion of the functionality of the system based on CWDM technology is implemented.
