About complex deliveries of the equipment of communication
and the organizations of primary multiservice networks

Dear sirs!

         We Offer you complex deliveries of the equipment of our manufacture and production of other manufacturers for the organization of the territorially-distributed multiservice networks - without large money and linings FOCL. We operatively develop schemes of primary regional and regional networks together with the customer on the basis of its technical project and typical decisions available us.

         More in detail about basic elements of the presented schemes. The organization of digital liaison channels to substations to which there are no cable lines is especially problematic. Especially we have developed for this purpose and we make idle time in installation and reception of sanctions of corresponding bodies a digital multichanel radio extension "RT-300" with speed of transfer up to 2 mbps (E1). There is also its single-channel, inexpensive version "RT-300/1E", 1-st telephone channel providing transfer (or RS-485) and Ethernet 64 kbps which optimum approaches for the organization of a universal liaison channel to small objects.

         RRE "R-150" a range of 150 MHz provides transfer of 6 digital channels on 64 kbps. Together with our multiplexers in them it is possible to organize carrying out of subscribers and channel Ethernet on distance up to 50 km. "R-150" it can be interfaced on port E1 to any equipment, including automatic telephone exchange and systems of a radio access, "is transparent" transferring the first 6 time-slots. The sanction to application "R-150" is not the big problem as it works in strips of frequencies earlier widely widespread RRE.

         About universal multiplexers of stream E1 of a series "MC-115T". We let out them in two dimensions – full channel (up to 30 ports) "MC-115T/27E", with dynamic distribution of channels under transfer Ethernet and small channel, compact (up to 4 ports) "MC-115T/3E". Last has only 3 telephone ports and one port Ethernet, but and costs all 1 thousand $ that allows to include in networks not only large objects. The multiplexer can transfer a stream (to FOCL) on copper pair, can work and with RRS.

         Transport basis of the primary network of area presented to you are RRE, systems of transfer and multiplexing of digital streams E1. Their high efficiency, and also decrease by new alternative operators of cost of rent channels create objective preconditions for the beginning the organizations of regional networks with application of rent of channels for transfer of streams E1. At occurrence in the customer own FOCL available primary networks of areas will be simply switched to the points of access in SDH. We have decisions on decrease in charges on rent due to use of one rented stream E1 for several units of a network (up to 5 units in one "ring" E1). At the today's price of "Rostelecom" in $ 5oun. In a month it turns out $1oun. For one unit. There are decisions and for application, in the extreme cases, allocated channels Internet.

         We have chosen the "purchased" switching "purchased" switching and distributing equipment as the most practical. The important condition of a choice of its supplier was its readiness to cooperate with the purpose of maintenance of an effective utilization of all systems in a complex. For example, on sites with greater flights and extremely low possible speeds of transfer we can optimum configure "purchased" automatic telephone exchanges, the IP-equipment and systems of a radio access with our equipment, it is literally with step in one time-slots, having provided a basic opportunity of the organization of a multiservice network without expensive FOCL and high-speed RRW. Also we consider, that it will be convenient to customer to receive all equipment under the project at once and from one hands. All it can be collected and tested in our shop, it is accepted the customer "on a turn-key basis" and is sent to it by one container.
