High-Frequency Communication Equipment CVK-16 Revision 3 for Effective Data Transmission

High-frequency communication equipment "Digital High-Frequency Channel-16" (DHC-16) Revision 3 is designed for organisation of telephone channels, telemechanics channels and data transmission of machine-to-machine exchange via high-frequency communication channels on the basis of power lines in the band from 4 to 64 kHz. The equipment supports analogue, mixed and digital transmission mode. In the digital mode in the base frequency band of 4 kHz the possibilities of multichannel transmission with the speed up to 42.0 kbit/s are realised, including Ethernet channel, up to three digital telephone channels (G.729 ITU-T), up to four MMO or TM channels with the speeds from 100 to 1200 bps. The CVC-16 equipment (Revision 3) has three modifications: <ul> <li>- CVC-16T with the ability to operate in the base band of 4 kHz and nominal bandwidth up to 64 kHz;</li> <li>CPK-16 PT with the ability to organise digital conversion in any 4 kHz baseband, as well as allocation-addition of 4 kHz bands at the reacceptance point;</li> <li>CVC-16 MT with the possibility of operation in the baseband 8 kHz, 12 kHz or 16 kHz.</li> </ul>
