/KASE, Jan.06, 00/ - According to listing requirements, "KAZAKHTELECOM" (Almaty, official list of securities, category "A") provided Kazakhstan stock exchange (KASE) with the information on implementation of National satellite communication network (NSCN) DAMA project. NSCN DAMA is to be built in five steps. Presently, "KAZAKHTELECOM" carried out zero, first and second steps of the project. Within these steps 52 DAMA stations has been installed, including: in Atyrau region - 15 (8 - in test use), in Mangistau region - 8 (4 - in test use), in Kostanai region - 3 (all in test use), in Pavlodar region - 2 (all in test use), in Almaty region - 4 (all in test use), in Aktobe region - 8, in West Kazakhstan region - 2, in North Kazakhstan region - 8, in East Kazakhstan region - 1, in Astana - 1. Total of 21 stations are in use now. Till the end of 1999 "KAZAKHTELECOM" plans to: - put into operation 18 stations in three regions: Aktobe, Atyrau and Mangistau; - set up 50 stations in seven regions: Karagandy - 6, West Kazakhstan - 11, Aktobe - 6, Kostanai - 3, Almaty - 9, Jambyl - 12, South Kazakhstan - 3. DAMA stations will be controlled by a central station in Almaty. Reserve controlling station is to be set up in Astana. The network is to be used to transmit mainly voice signals, since channel traffic equals 8 kb/sec. Remote stations have from 4 to 16 channels, satellite stations in regional centers have 30 channels. Major purpose of NSCN - provision of stable, affordable communication for Kazakhstani cities notwithstanding their remoteness. The network is built on principle close to radial-joint: information is exchanged between remote stations through joint transition stations, located in each regional center. Equipment of remote user is connected to small satellite terminals. Signals of both remote single terminals and corporate telephone stations can be sent via the network through their access to the telecommunication network of common use (TNCU) connected to central controlling station. All objects of NSCN have united controlling system. To connect two remote stations, an inquiry should be made at central station, which in turn makes inquiry of another remote station, and if the station is free a temporary channel is built between two objects.
