Questions of centr~.lization and automation of the servicing of GTS [municipal telephone network] equipment, the monitor- ing and control of the network, the implementation of signal- ing system ~'o. 7, handling subscriber accounts and optimizing network planning are treated in other articles of this topical - selection. Our nation has well developed electrical communications networks: municipal, rural, intrazonal, long distance, international and institutional telephone networks; telegraph networks including facsimile cotrnnunications and data transmission facili-� ties; satellite communications, television and broadcasting systems as well as radio networks; a postal network which does not age and with the introduction of "electronic mail" will enjoy a second birth, as well as a widescale printed material dissemination network. The telephone was and will remain for the f.oreseeable future the most popular, acces- sible and rapid means of communication by people over distances. Tne nation's populace, organizations, enterprises and institutions are interested in the expan- sinn of local, especially municipal telephone service. This i~ responsible for the constant attention siven to municipal telephone networks, wtiich is manifest by party, management and planning organs. 1 FOR OFFIC~AL USE ONLX APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 ~ E'UR OF F7CIAL U5E ONLY Ttie 1976 decree of the USSR Council of Ministers concerning the acceleration of. the development of the nation's teleph~ne service was a program document For til~. activity of all communications workers of municipal telephone networks. This decree became the basis for the resolution of many questions in the expansion of GTS's: the construction of ATS [automatic telephone exchange] buildings, the financing of the installation of the production process equipment, the development and introduction of new GTS hardware, the development of equipment fer the time metering of the cost of local telephone conversations and its introduction on the networks, as well as ~ the sale of telephones through the connnercial network and a number of other ques- . tions. The plan assignments for the development of the GTS in the lOth Five-Year Plan have been overfulfilled. Automatic telephone excYianges with an overall capacity amount- ' ing to ~bout half of what was done over the preceding nine five-year plans have been placed in service; the installed capacity of crossbar ATS's has morP than doubled, the number of telephanes people have has aln~ost doubled and the number of pay phones has increased by a factor of 1.3, something which is especially import- ant given the rapid growth of residential construction. Simultaneously with the expansion ef the network, work has gotten underway on its automation, which has reached 9y.Y percent over these years. The tasks of the 26th CPSU ~ongress of increasing the ntianber of telephones by a factor of 1.3, including those installed for the populace by a factor of 1.4 times, require a significant increase in the volumes of planning, installation and con- struction, start-up and alignment work as well as the production and delivery of a large volume of GTS equipment. The main tasks of the subsector remain: the mastery of new GTS equipment, boosting its operational efficiency, improving operation and improving the quality of service [1, 2]. Modern GTS's are complex technical engineering complexes, which include: civilian facilities (ATS buildings and junction centers); sanitary engineering facilities which provide for the requisite temperature and humidity conditions (air condi- tioners, refrigerators, ventilation equipment, etc.); ATS switching equipment and the switching equipment of junction centers; the equipment for intercenter and ~ interexchange service, including physical and multiplex communications links and channels; line equipment shops witti the transmission system equipment; alternating and direct current electrical power supplies; line and cable facilities, repair and restoration services and a number of auxiliary services. At least three conditions must be met in order to support the operation of all of this complex equipment in interacting together and make good quality service available: reliable units and equipment; skilled servicing personnel with staffing in accordance with servicing norms; technical standards and instruction materials on the operation of the units and equipment. New kinds of equipment, cables, instruments, etc. have arrived over the yeara of the lOth Five-Year Plan for municipal te~ephone networks. Primarily crossbar and ten-step ATS's are being used as the switching equipment on municipal telephone 5 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2407/02109: CIA-RDP82-00854R000400050069-7 FOR OFFICIAL l1SE ONL1' networks. Crossbar and ten-step systems are used to build both the ATS's directly and the incoming, outgoing and long distance traffic centers, as we11 as the reference-information and special services centers. The main switching equipment is an aTSK [c.rossbar automati~ telephon~e exchange] of _ domestic design, which is produced by plants in the U~SR, GDR and CSSR. During the years of the lOth Five-Year Plan, work was done ~:o improve the ATSK equipment. In 1980, series produ~tion of the ATSK-U was started: an improved type of crossbar ATS. - The improvements involved approximately 65 percent of the ATSK equipment and new kinds of instruments and control panels appeared in the equipmer~t complement, which were designed to improve the operation of telephone exchanges [3]. The moderniza- tion was expressed in the refinement of the subscriber set (AK.), the coder equip- ment, the information transmitting and receiving devices, as wel~ as check and test equipment, power supply circuitry and electronac equipment appeared in the equipment complement of exchanges. The improvement~ were directed towards increas- ing the reiiability, reducing the requirements for productior~ ~rocess areas and curtailing the installation and operational costs. On the uahale, the space require- ments of the automatic s~aitch room of a 10,000 number ATS with seven-place numeration were reduced by 15 percent through the elimination of 50 ~ubscriber set racks and 15 dial-pulse coder equipment racks. The second major type of GTS switching equipment contimues to ~e the ten-step system ATS's: the ATS-54A. The third type, which has appeared recently, is a crossbar of the ATS "Pentakonta-1000S" system, which is produced in Polish Peoples Republic under French license [4, S] and which is adapted for operation on the municipal telephone iiEtworks of the USSR. Moreover, there are ATS's of other systems in various amount.s on municipal tele~ phone networks: mechanical, different variants of ten~-step and crossbar type ATSK-100/2000 (rural type) offices. Of course, it would be better to have the same type of equipment on the net~�T~rks. This is mor~ advantageous from the viewpoint of production, installation, o~eration, spare parts as w~e11 as personnel training. However, the pace of municipal telephone network development is such that there is _ not enough equipment of t.he same type and it is necessary to use different kinds. The introduction of new switching systems will begin in the llth Five-Year Plan on _ local networks. It will be necessary at ti~e same time to introduce systems of dif- ferent types: the quasi-electronic ATS's -"Kvar~s" (municipal telephone network), "Kvant" and "Isto::" (rural and possible municipal telephone exchanges), as well as the electronic off~ces - MT-25 and. DKh-100 (municipal telephone exchanges). Pri- marily crossbar equipment (ATSK-U) will be used, as before, as rhe switching cen- ters for municipal telephone networks, while ten-step equipment will be uGed in ~ small amounts. Moreover, it i-s possible that other types of ATS's will appear on the networks in limited amoun�5, in particular, the crossbar KMK-20T (Finland), the mechanical-electronic ARE-11 EYugoslavia) and other ATS's. Sucl~ a motley picture creat~s ~c~onsiderable difficulties, in particular, in setting up the interaction of exch3nges in a network, in providing them ~vith spare parts 6 FOR OFFICIAL IJSE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2407/02/09: CIA-RDP82-00850R000400450069-7 - FOR OFFICIAL l!SE ONL1' and in training personnel. A fixed condition for the introduction of imported ATS's is their adaptability to the existing network: it is necessary to retro�it an exchange, but not to supplement the existing network with too much equipment and to introduce supplemental intermediate equipment which enciunbers it. It is obligatory that the strategy of bringing the indicated ATS's on line be changed, accomplishing this by means of creating regions of equipment of the same type. Type NFT-25 municipal electronic ATS's will be produced in the USSR under license of the "Tompson" company (France); DKh-100 exchanges should be delivered by the "Telefenno" company (Finland); quasi-e].ectronic "Kvarts" ATS's are a development of the Leningrad "Krasnaya Zarya" scientific production association. The indicated - ATS's are exchanges ~oith control based on a recorded program. Either electronic or reed switc:~ (quasi-electronic) matrices are used as the switching fields in � them. Concentration switches (subexchanges) are provided as part of the ATS's, where these can be brought out at points remote from the reference ATS where there is a sharp demand for telephone. A savings in communications links and channels is achieved in this wa~. True, transmission system har~3ware appears an the indi- cated routes (line channel, terminal equipment), which requires servicing, even if a minimal amount, but the main thing is that rooms are needed for the concentration switches (subexchanges), electrical power supplies for them and the transmission system. This must be kept in mind when planning branch offices and in the overall engineering and economic substantiation for exchange construction. The municipal telephone networks in our nation were among the first in the world which started to use circuit multiplexing. At the start of the 1960's, the KRR transmission system appeared on GTS's, which was modernized and introduced as the KRR-M. After that, KAMA equipment arrived at the network: a transistorized variant of the KRR-M. This analog equipment makes it possible to obtain 30 telephone channels via a physical pair in a high frequency MKSG cable. In recent years, the widescale introduction of IKM-30 digital transmission systems [6] has started on interexchange links, where these systems use pulse-code modula- tion at a rate of 2.048 Mbit/sec, which makes it possible to set up 30 telephone channels via tw~ pairs of conventional low frequency cable using at least one additional physical pair for remote signaling and monitoring. The IKM-30 transmission system is an equipment complex which includes the matching devices and the line channel with the unattended repeater stations, spaced 1.2 to 1.7 km apart. And the system can be put in service only by providing for the complete delivery of both the main and the intermediate equipment. The IKM-30 is electronic equipment which is technologically suited to manufacture; it is anticipated that in the near future i~ will he produced in rather large volumes, as a result of which, it will become possible to curtail the use of KAMA equipment which employs scarce trunk communications MKSG cable. THE IKM-30 equip- ment will find widescale applications on municipal telephone networks given the ~ condition that it will be modernized and the plant will assure high quality of its manufacture, 7 FOR OFFICIAL L15E ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2047102109: CIA-RDP82-00850R400404050069-7 FOR OFFICIAL USE ONLti' The secondary IKM-120 system [7] has been designed around the IKM-~0 for zonal network. Following its testing under GTS conditions, it will poss:ibly appear where high capacity bundles of junction lines are needed. One of the important components of GTS's is the line and cat~l~a fa~ilities-. These include the following: the telephone ductwork, its inspection devaces, rammutators, cable and open wire lines (including, inter-otfice, inter-center, trunk and sub- scriber lines), cable pressurizing equipment, cable entrance l~ous~es as well as . cable terminal and subscriber sets. - Telephone conduits have undergone slighz changes with time: asbes[~s cement pipes are layed instead of concrete blocks, and the inspectfon devic~s la~ave become large in volume. Polyethylene pipes have not as yet found widescale appli~ation on the networks. The increase in the volume of inspection points is dictated batxl by the creation of more comfortable conditions for working in them and '~q tk~e a~pearance of new types of cables with an increased~:bend radius: type 'TPP' polyethylene jacketed cable and TSShp corrugated steel cable. - The major type of GTS trunk cables is TPP cable of var.ious capacities of up t.o 1,200 pairs a current conducting core having diameters of 0.4 and 0.5 mm. Recently, TPP type cable has appeared on the network, wl~ich has a core of 0.32 mm with the same pair capacity. Its deliveries amount up to 10 percent of the overall volume of cable deliveries and will increase in the future. The same TPP cable, but with up to 2,400 pairs, is undergoing trial op~ration and is being prepared for series production. The lead jacketed TG cable, as before, remains the most reliable, i.e., is the - least subject to faulting, but is used primari~y for inter-center (MUS) and inter- office (MSS) communications. Type TPP cable is likewise finding application here where a backup route is available, which has been set up for TG cable. With the introduction of the IKI~i-30 transmission systems,TG cable has come to be widety use.d to multiplex the indicated systems. For rNS and MSS municipal telephone networks, type MKS high frequency cable is also used, which is run where it is necessary to set up channels based on the KAMA (or KRR-M) analog transmission system. Imported cables are used in small amounts on the networks, and their parameters are either close or identical to the parameters of domestic cables. Experimental fiber optic communications lines have been created on a ntunber of GTS's. The introduction of factory models of optical cable is anticipated i.n the llth Five-Year Plan, which as part.of a complex ~vith digital. transmission systems will provide for the organization of high fidelity communir_ations channels.

A KDV-10 unit has been designed, which is intended for the connection of 100 cables. Its intro- duction will assist i.n reducing the technological arPas reqiiired for the housing of compressor installations and provide a constant air pressure for a greater number of cables from a single installation. It should be noted that with the overall considerable technvcal progress in municipal telephone netwo?-ks, such important network components as the terminal units (distributing frames, boxes, and to a certain extent, distribution boxes) have remained practically the same as they were at the dawn of the development of communications: cumbersome, requiring a large metal consumption and with a tradi- tional"screwed down" connection. The demand of the sector for the development of modern compact and highly reliable cable terminal devices has not yet been satis- fied over a period of several years now. . The starting and te rn?inal component of a municipal telephone network, just as for the entire Unified Automated Communications System, is the telephone set. In becoming the property of a subscriber, it has remained an important component of the telephone network, having an impact in many respects on the quality of service. ~or this reason, the observation of the regulations for its operation and good maintenance are important now as never before. ~ Various types of telephones are used in the terminal subscriber units, including sets produced by CEMA member nations. Telephones of an improrved design and with better electrical acoustic parameters are being developed ("Gamma", "Gaysma", TAN-80,etc.). The ATM-69/2 pay telephone has been designed and a table-top pay phone is being developed. Telephones with push button dialers, using both battery and frequency transmiss~on methods, telephone accessories of various types ("Viza-32", "Trel'-1", "Trel-2", with built-in calculators, electronic clocks, timers, etc.), which are intended for automating numUer di.aling and increasing the subscriber to equipment ratio in the institutional sector, will find widescale applications in the future. As far as the civilian facilities of municipal telephone net~aorks are concerned, they are built in accordance with standard project plans. The construction of ATS buildings of a municipal construction style with a large glass covered area has finally passed, something which has a negative impact ~n equipment operation. Modern stand ard ATS buildings (automatic switch rooms) have the minimum requisite illumination via narrow window openings. The introduction of quasi-electronic and electronic switching systems on the network requires additional study of the design principles of municipal telephone - n~tworks. This question needs to be thoroughly worked through by scientific and planning organizations, but a general trend can be seen which has developed during the process of network expansion. 9 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2407/02109: CIA-RDP82-00854R000400050069-7 ~OR OFFIClAL USE ntiLl' Following the ten-step ATS's, crossbar type ATS's begin to appear on the telephone networks, which had a number of advantages (a high speed multifrequency code, remote control of a connection, the existence of a pressure contact in the elec- trical circuit, etc.). In order to preserve them, crossbar ATS's were introduced so that an ATSK subscriber was connected to the subscriber of another ATSK through a purely "crossbar" telephone line, while the subscribers of ten-step ATS's were connected through a"ten-step" line. Only one transition is permitted when con- - necting a crossbar ATS subscriber to a ten-step subscriber: at the point where a transition is provided by means of supplemental equipment from one type of signal- ing to another. Such a network construction is dictated by the design of the incoming and outgoing - traFfic centers of the different types: the ten-step and crossbar. Considering the fact that they are tied together and to the ATS's by different trunk groups of junction lines, it can be said that the crossbar ATS's were introduced and are being introduced by means of creating a parallel network ("segregated", "superimposed"). From the viewpoint of network design, the introduction of quasi-electronic ATS's should not cause any difficulties, since the signalling system and its capabili- ti~s are similar to the system of crossbar ATS's and the signal switching takes place in analog form, i.e., quasi-electronic ATS's can be inserted in the exist- ing crossbar centers without additional equ~pment. A quasi-electronic center variant design is possible where crossbar ATS's can be tied i~ito them. The governing factor here is a specific project plan and the requisite volumes of the various types of equipment. Signal switching is accomplished in digital form in electronic ATS's. The con- version of the signal from analog to digital form is an expensive operation. It is necessary to make an effort to see that there is a minimum number of such transitions on a network, and even better, th ere is only one (similar to the situation with battery and frequency codes in the case of inechanical ATS). For this reason, the possibility of creating a"superimposed" electronic communica- tions network is b eing examined, in which both the ATS's and the centers as well as.the transmission system (a PCM system) operate with a signal in digital form and the transition to the analog network is made only once. Considerable work has been done over the years of the lOth Pive-Year Plan to improve the operational level of GTS facilities and improve the service quality. Eltctronic automatic number identification equipment, electronic pulse pairs, electronic dial-pulse registers and matching devices are being installed in municipal ATS's; new types of connector relays are being introduced (RSLP, RSLU-M - and RSLI-G). The networks are being outfitted with new monitor and test equip- ment: the PRSL-2, AL, UNE, POV, PKU, PKNP-AON and others, as well as the INIR, IIV and PKP-4 and other meters. All of the indicated equipment and instrimients have been desi~aed for one purpose: to improve ttie operation and increase the labor pr.oducrivity of servicin~ personnel. A great of work has been done to improve the quality of service on AMTS--GTS-- --UATS [automatic long distance component exchanges--municipal telephone 10 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2007/42/09: CIA-RDP82-00850R000400050069-7 FOR OFFICIAL USE ONLY exchanges--agency automatic telephone exchanges] sections. The fact is ttiat by using long distance automation and in this case, occupying the expensive facili- ties of through-working centers and channels, a subscriber in some cases is not able to "break_through" to the subscribers of agency telephone exchanges because of the lack of junction lines on the section between the reference automatic telephone exchange and the agency ATS. Work has been organized to bring the number of junction lines into an agency ATS up to standards. However, not everywhere. There are objective reasons for this, for example, the lack of the requisite equipment on the part of departments. In this case, it is necessary to limit the capacity of the agency ATS which has an output to the municipal tele- phone network. But there are still networks whose workers have not realized the importance of the ~~ork to be done and it has not been organized as the situation requires. There are so-called hard to dial numbers (in the case of long distance service) on some networks. In this case, the municipal networks are obligated to work with the subscribers and ascertain the necessity for installing additional telephones for them, which are to be used for incoming traffic. This will also promote an improvement in the quality of long distance service. Very special attention is now being devoted to the area of toll order junction lines and the junction lines between automa~ic long distance exchanges and munici- - pal telephone exchanges. It has remained practically without any good monitor and test equipment. The measures, which were planned in conjunction with the specialists of long distance telephone exchanges, local networks and designers, will make it possible to solve this problem in the immediate future. Quality control of the equipment being produced has been set up at the supply firms by specialists of the USSR Ministry of CoMmunications. The analysis of exchange operation has been organized with the presentation of annual reports on equipment defects to the manufacturing plants and foriegn companies, for the purpose of improving production technology. The existence of a complex set of equipment on a network requires a high degree of professionalism and a constant increase in skill levels. Courses have been _ set up on an annual basis for municipal telephone network workers: for the training of brigade workers of the adjusting brigades for ten-step system ATS's; for the study of crossbar ATS's, the "Pentokonta" system, automatic number identification equipment, new types of cables and their pressurization, new equipment on the line facilities of municipal telephone networks as well as new methods of operating _ them; for improving the skills of engineering and technical workers and engineers separately in production electrical measurements laboratories as well as the study of new equipment and improving the skills of directors and chief engineers of municipal telephone networks. Thus, by taking a break from production work, the skills of about 3,000 engineering and technical workers of municipal telephone networks are being improved annually. ~onstant attention is being devoted to the study, dissemination and introduction of advanced methods of labor by means of publishing descriptions in journals, in express-information as well as publishing special placards and making films. 11 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 FOR OFFICIAL USE ONLY Individual advanced methods of labor for municipal telephone networks were dis- cussed at a staff ineeting of the USSR Ministry of Conanunications: the work experi- ence of subscriber line shop brigades; cable worker and splicer brigades as well as the brigades for servicing pay telephones. The brigade method of servicing the facilities of municipal networks has been introduced on an experimental basis in the Leningrad, Chelyabinsk, Kiev and a number of other municipal telephone networks. Motion picture films are being made on the following topics: servicing pay tele- phones; checking the operation of pay telephones from monitor consoles (SKTA); servicing the IKM-30 equipment; cable facilities; and a cartoon "Take Care of the Pay Telephone". These films are sent out for motion picture release in each republic, oblast and kray center. All-union conferences of municipal telephone network workers are held regularly once every three to four years to Pxchange experience with the operation of municipal telephone network facilities. The last conference was held in October of 1980 in Tashkent (see ELEKTROSVYAZ', 1981, No. 4). Comprehensive communications quality control systems (KSUKS) are being introduced. To instruct the municipal telephone network workers in the introduction of KSUK's, a brochure has been prepared as well as procedural instructions on this pro'~lem [8]. 'I'he operational efficiency of municipal telephone networks depends in many - respects on the operational organization of the entire camplex municipal tel~phone network equipment. Designs are still encountered where operational questions are either given a secondary role or they are completely forgotten about. In this case, new equipment appears which has not been provided with monitor and test or specialized measurement equipment. And without it, or without it being imple- mented based on computers with program software, correct and proper operation is impossible, and consequently, a high service quality cannot be guaranteed. It is planned that future ATS's will be equipped with diagnostic and faulty unit localization instruments, and the servicing of ATS's will practically consist of replacing the damaged functional modules, and their restoration (repair) will be accomplished at special repair centers, which are yet to be created, or if agreed upon, at the manufacturing plants. A consequence of this should be a sharp reduc- tion in the staff of. operating personnel in the automatic switch room, but it will also become necessary to have highly skilled specialists for the se~vicing of the - SUVK's [expansion unknown], who possessthe requisite amount of knowledge of math- ematics, programming, electronics and communications. Work is underway now on _ the specialization of students in the final courses as well as the creation of a new specialty in the higher educational institutes and communications technical schools. Until recently, the major method of oper.atin~ the exc}iaii~e fac ~_ics of tlte municipal. lelephone networks taas preventive mai~lten~rice. ~ssence of tlle method consists in planned inspections and monitoring of equipment operability FOR OFFICIAL U5E ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2007/42/09: CIA-RDP82-40854R040400050069-7 FOR OFFICIAL USE ONLY and the elimination of the defects which were found. Naturally, with this tech- niqse, labor expenditures for operation are high. Given the conditi~~ns of a shortf all of labor resources and the necessity of improving the eff iciency of telephone networlc operation, the question has come up concerning the implementa- tion of new, more progressive servicing methods. The first such attempt was the method of curtailed preventive maintenance. How- ever., with a certain real reduction in labor expenditures, the danger of degrad- ation of cammunications quality arose, since faults, especially in mechanical ATS's, will as before continue to occu~:, but they will not be detected and elim- inated in an operationally timely manner. The most promising servicing system ~s the monit.or and correct method of opera- tion (KKM) [9]. The essence of it consists, first of all,.in setting norms for the communications quality indicator�s, i.e., establishing their threshold values, and secondly, having servicing personnel interfere in exchange operation only when these values are exceded. A preparatory period should precede the transition to the monitor and correct method of servicing telephone exc}ianges and centers. This period is different in different networks and exchanges and is determined by the amount of time needed for the following: the pe.rformance of a complete one-time preventive check of the equipment; making t}iose corrections which have not yet been made in the switching equipment itselE as well as the monitor and t:_~st equipment for the purpose of expanding its diagnostic capabilities, and the remote fire alarm " signaling devices in an exchange: and checking their operability in a facility which is attended around the clc~ck; and finally, to study the instructions on KKM and train soecialists in wo~rking using the indicated technique. An ever greater number of networks is operating every year using the monitor and correct method operation. It is true that its introduction is complicated by the lack of automated equipraent to monitor the quality of the servicing (for example, to monitor the threshold values of failures to make connections). However, the method has been adopted for widescale implementa~ion, since even in the case of manual monitoring of communications quality indicators (call servic- ~ ing), a perceptible reduction is acliieved in labor expenditures. Instructions ~ave been worked out for the :Lmplemntation of KKM in servicing crossbar systems and the same instructions are being prepared for ten-step ATS's. The widescale implementation of the monitor and correct~:method is opening up prospects for the centralization of network operation. If constant servicing of an exchange or center is not provided, the skilled operating personnel of se~reral ATS's can be concentrated ei1_her at one of tlie ATS's or at a center, and since interference in the operation of an exchange will take place only in cases where the communications quality indicators fall below the threshold values, the number of servicing personnel can be significantly reduced. Centralization of the staff of servicing personnel, equipping the staff with the technical hardware for ubserving communications quality, for data display 13 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2407/02/09: CIA-RDP82-00850R000400450069-7 FOR OFFICIAL USE ONLY and intervening in ATS operation will make it possible to create highly organized technical operation centers (TsTE). Prior to the development and deliveries of the new technical hardware, the existing equipment must be used for the technical operation centers, as has been done on the Moscow, Leningrad, Tashkent municipal telephone networks, as well as a n~ber of other networks, where technical opera- tion centers are right now being created. An invariable condition for the intro- duction of technical operation centers should be the actual reduction of staffs; it is impermissible that in the rush to follow the style of the day (the utiliza- tion of computers, computer centers, etc.) instead of each installer which is eliminated it would be necessary to have to add a highly skilled engineer to the staff to service the computers and specialized complexes. The further development and refinement of the centralization of technical operations will be seen in the creation of automateci control systems for municipal telephone networks. Automated centralized operation should be the basis for the autamated control system for municipal telephone networks (ASU-GTS), and become its major techno- logical subsystem along with the other governmental plan subsystems. The correct operational organization of municipal telephone network facilities depends in many respects on the implementation of instructions and production process schedules for operational servicing of all kinds of GTS facilities, which are being developed, published and sent out to the sites on a regular basis. The listing of the main documents which the municipal telephone networks are obligated to utilize in municipal telephone network operation are: instructions and production process charts for servicing ten-step ATS's (of the ATS-47/'S4 type); instructions for the operation of municipal crossbar ATS's of tl~e ATSK type (ATSK-U); for the set-up and operational acceptance of municipal type ATS's; for the installation and alignment of automatic number identification equipment; for the operation of automatic number identification equipment; f or servicing elec- trical power supplies; for the construction of the line facilities of municipal telephone networks; for laying cable in permafrost regions; for installing type TPF, TPPZ and other cables; for the aligrnnent and operation of KAMA equipment; temporary standards for the consinnption of spare parts and materials for the current maintenance and repair of li~e and exchange facilities of municipal tele- phone networks; temporary instructions for the measurements and operation of IK1~1-30 equipment; the following olbigations apply to management: those for ~ establishing data sheets for line facilities of municipal telephone networks; for the electrical measurements of line installations; for the design and corrosion protection of underground metal communications structures; written instructions for servicing compressor and signa:ling installations as well as an entire series of other management materials. The communications ministries of the union republics and the production and engineering administra~ions for communications should get these docwnents to the network caorkers. In conclusion, one can formulate certain problems which confront mur~icipal tele- phone networks specialists during the llth Five-Year Plan in light of the overall task of increasing production efficiency: FOR OFFICIAL USE ONI,Y APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400050069-7 FOR OFFICIAL USE ONLY --The fastest possible mastery of new municipal telephone network equipment: its study, introduction and utilization at maximum possible capacity for the purpose of bringing the percentage of installed municipal.telephone network capacity in service up to 92 to 93 percent, as well as accelerating the recovery of funds extended for construction; _ --Selecting optimal, thoroughly worked out project plan solutions, which take ~ into account future equipment; it could be that under conditions of large - electronic ATS's (up to 50,000 - 60,000 numbers) using high capacity trunk groups of junction lines, optical cables and digital transmission systems, it will prove expedient to dispense with traditional junction center formation; this and other questions of the design of the networks of the future require serious engineering and economic substantiation work; --The development of the network of junction lines to agency ATS's, something which will allow for not only high quality service with long distance automa- tion, b ut also improve the quality of local service for enterprises and organ- izations having agency ATS's; --Improving the operation of municipal telephone networks by means of further automating them while simultaneously or subsequently centralizing the networks; correctly utilizing the monitor and test equiFment; all possible support of the initiatives of specialists for the design of new automation equipment; --For the purpose of reducing the load on municipal telephone networks, install time metering equipment for the cost of local conversations, APUS, with a uniform system of rendering subscriber accounts.
