4 digital TV channels in one analog
channelon existing analog RRL
For countries with large extension of existing analogue radio-relay lines the modernization of these lines fordata transmission seems to be the most simple and cheap way to provide the transfer of the telecommunicationnetwork to digital methods of transmission and processing of information.
Existing analogue radio-relay UHF equipment with frequency modulation may be easily applied for 34 Mbpsand 51 Mbps (STM0) data transmission.
Our specialists have vast experience in transmitting 34 Mbps data streams via existing radio-relaychannels. In course of corresponding modernization only terminal equipment is to be replaced. Our solutions allowto retain existing control, protection switch and service communication systems without any alterations and createhybrid analogue - digital telecommunication systems with common protection channel on the basis of existing
analogue radio relay systems. Such approach allows to develop digital network step by step in case of lack ofinvestments.
34 Mbps digital modems and digital TV encoders will allow You to transmit up to 4 TV programs via oneanalogue radio relay channel. Released channels also may be used for data transmission.
