RRL equipment

NTC Energozvyazok uses RRL equipment from such manufacturers as Ericsson (Sweden), TTC Marconi s.r.o. (Czech Republic) and Nokia Siemens Networks (Finland). Direct deliveries of RRS equipment are made:

MiniLink TN is a line of high-reliability PDH and SDH radio relay station equipment. New modifications of this equipment allow 600 Mbit/s traffic to be transmitted;
FlexiHopper Plus — equipment of PDH system radio relay stations with a budget price and a good price/quality ratio. New modifications of radio relay equipment produced by Nokia Siemens Networks are oriented towards the organization of joint TDM and Ethernet traffic. Trunk throughput reaches 300 Mbit/s.

In its production activities, «NTC Energozvyazok» focuses on the equipment of radio relay stations in such a way that the control and monitoring system is unified for the entire communication complex, incl. for multiplexer equipment and power supply systems. In this connection, the customer is offered «RRS-multiplexer» complexes with a single control system and from one manufacturer. Such complexes are:

PRS MiniLink — PDH multiplexer type RSM-30U;
The FlexiHopper Plus PDR is a PDH multiplexer of the FMX type.

SDH multiplexers of the same manufacturers can also be used, if the work project requires a transition to RRL — VOLZ. The newest RRL equipment can be directly connected to the VOLZ network via an optical cable.

The latest modification of RRL equipment produced by Nokia Siemens Networks and Ericsson allows connecting radio modules via an optical cable. Such a solution is convenient if the «last mile» links are organized from the direction of VOLZ main network. In this equipment, the RRL supports both packet and synchronous (SDH) communication technologies with the VOLZ.
