Last-mile data-transfer RRL

Technical solutions for a RRL that occupies an intermediate position between the TV and telephony markets are considered. A last-mile data-transfer RRL is proposed. Since the overall stream rate is not high, the issue of frequency band saving is not acute. The RRL group signal shaping is achieved at the first intermediate frequency of 1-2 GHz with the 2-13 GHz conversion. The RRS module set provides the transfer of E1/E2 telephony streams, Internet-Ethernet 10 base T data flows, TV channels transmission from one head-end to others. The implementation of home satellite television techniques has enabled the use of well-established technical solutions offering reduced costs of the RRL data transfer.
