1、c9 Page 1 Recommendation T/SF 44 (Odense 1986) COMMERCIAL AND MARKET ASPECTS OF BUSINESS SERVICES BY SATELLITE (BSS) Recommendation proposed by Working Group T/WG 7 “Services and facilities” (SF) Text of the Recommendation adopted by Commission “Telecommirnicntioons”: Part 1 - GENERAL CONSIDERATIONS
2、 Introduction This recommendation deals with the commercial and market aspects of Business Services by Satellite (BSS). It does so in an overall manner, and covers a broad time scale. Reference to further recommendations from other Groups is required. BSS have been considered from the viewpoint of S
3、ervices offered and their commercial strengths and weaknesses. Some of these Services may compete with terrestrial systems for trafic and the factors that wiil influence the use of O BSS have been included. “The European Conference of Posts and Telecommunications Administrations, considering - that
4、international digital business services are now offered by two international organizations: Intelsat and Eutelsat, and that these organizations utilize different satellite systems, each of which requires a unique type of earth station, - that BSS include some unique new services, - that BSS are an a
5、lternative to some other services provided by e.g. ISDN, Broadband, - that the total market is to be shared between Broadband, ISDN and BSS, etc., services, - that factors which determine the market share of BSS need to be identified, - that intermediate plans include newer satellites using current
6、technology up till 1992, - that long term plans are for new satellite technology, effective after 1992, - that North American standards are not the same as those in Europe, - that the foliowing factors are in favour of the use of BSS: (a) the possibility of satisfying emerging demand immediately at
7、both European and national levels; (b) broadcast/point-to-multipoint service availability; (c) the possibility of providing the service to the customer with a shorter lead-time by using transportable terminals, O - that the following factors may not be in favour of the use of SMS systems: (a) percei
8、ved lack of condentiality; (b) transmission delay; (c) limit to number of hops, - that newer satellites will be available at approximately the same time as ISDN implementation, i.e. 1989 onwards, - that there is pressure from outside CEPT for standards in certain services, recommends Marketing - tha
9、t when administrations exploit the Bearer Services provided by BSS, they have regard for: (a) the matters described in CEPT Recommendation T/SF 46 “Services Appropriate to Systems”; (b) the identification of factors determining traffic and market share; (c) the strength of BSS in relation to particu
10、lar markets; (d) the possible migration of trafic between alternative systems, and the consequent effect on the viability of the systems concerned, O Edition of November 15, 1986 - T/SF 44 E Bearer Services - that as a minimum, BSS should provide Bearer Services at 64 kbit/s and 2 Mbit/s, - that the
11、 Bearer Services should relate to emerging standards from CEPT and CCITT e.g. 384 kbit/s, - that the Bearer Services should relate to emerging standards from CEPT and CCITT beyond 2 Mbit/s e.g. - that the Bearer Services must relate to the bit rates to be used for ISDN, and Broadband Services, - tha
12、t the market advantage to BSS at rates higher than 2 Mbit/s should be exploited, Senice Configuration - that the required Service Configurations should include: 34/10 Mbit/s, (a) Point to point, unidirectional; (b) Point to point, bidirectional; (c) Point to multipoint, without return channel, and f
13、or further study: (d) Point to multipoint, with return channel (Note) ; (e) Point to multipoint, with Polling; (f) Point to point, unidirectional, with return channel (Note), Note: the capacity of the return channel is to be considered; and the nature of the return channel is to be considered (e.g.
14、terrestrial or satellite). - that the advantage of BSS for point to multipoint should be exploited, - that the availability of transportable terminals (Earth Stations) should be exploited, Service Occupation - that the occupation of BSS should be offered to customers as follows: (a) Full-Time Bearer
15、 Service (Permanent) (b) Part-Time Bearer Service (Reserved) (equivalent to a classical leased circuit), (equivalent to a circuit leased for a fixed period) scheduled at a fixed time each day; scheduled at a frequency other than daily, for added flexibility in marketing, e.g. weekly, monthly, (c) Oc
16、casional Use of Service (Reserved) with reservation a set minimum of time in advance of required use (e.g. 48 hrs); with special consideration concerning transportable terminals, (d) Random Use of Service (Demand) with no notice required; with the Administration retaining control, - that charging fa
17、cilities should provide the flexibility to relate charges to costs and the meeting of competition, - that time charge units should be similar for all BSS services, - that these charge units should be related to terrestrial system units, Quality of Service - that a statement of the minimum Quality of
18、 Service parameters necessary to satisfy the market demand for BBS - that these parameters may be considered different from those identified for other services and may influence the should be made, costs for the provision of the service, Edition of November 15, 1986 CEPT T/SF*44*E 86 M 2326414 00093
19、93 1 W T/S 44 E Page 3 O Supplementary Services - that the offering of Supplementary Services should be considered (for further study), - that as far as possible, standardized Supplementary Services should be offered, - that the dependence of BSS provision on the Terrestrial Infrastructure should be
20、 considered, - that the necessity for East-West and Intra-European connectivity should be satisfied, - that the necessity for interconnection between countries where the transmission facilities are different should be considered (e.g. hierarchical bit-rate differences such as 2 Mbit/s in Europe to b
21、e connected to 1.5 Mbit/s in North America), Applications - that, when Administrations exploit the capabilities provided by BSS, they have regard for the applications, e.g. (includes High-Grade Satellite performance, full connectivity with all transponders in use, security), Fast Facsimile, Video Conferencing, Remote Newspaper Printing, High Speed Data Transmission, Electronic Mail, etc.” O O Edition of November 15, 1986
