1 Access: From Interconnection to Convergence Yale M. Braunstein School of Information University of California Berkeley, CA (U.S.A.) March 2008

2 Access has several dimensions  (Physical or geographic) proximity  Possession of needed skills  Economics  For free or fee-based  Connection to (the) network

3 History (U.S. Telephony)  Competing networks  Bell & Edison in the U.S.  Resolved by patent decisions  “The fundamental principle, formulated by AT&T president Theodore Vail in 1907, was that the telephone by the nature of its technology would operate most efficiently as a monopoly providing universal service.”fundamental principle  New technologies & business plans lead to bypass (MCI) and interconnection (role of SS7)  UNEs (unbundled network elements)  More new technologies (now digital)

4 Issues are inter-related  As new entrants enter a telecommunications market the problem of interconnection has two dimensions: technical and economic. My focus is on the latter.  Often there is the view that it is in the national interest to encourage the widespread diffusion of the telecom network and to promote access by users who might not be considered economically viable by operators.  Interconnection and universal service are often linked.  Presentation of some of the issues  Optional “mini case studies”

5 Outline  Interconnection  Interconnection & universal service  Convergence (which has many meetings)  Competition (?)

6 The dimensions of interconnection  B.C. (before competition) it was common to see some or all of the following: Local tariffs were averaged across customers. In addition, the non-traffic-sensitive portion of the tariff was often kept artificially low. The tariffs for trunk calls were sufficiently higher than costs so as to enable the costs of local service to be kept low. International rates were many times the cost of service.

7 Typical interconnection pricing philosophies  Cost-based  Price-based  “Bill and keep”  Private negotiation

8 Additional concerns  Equal treatment and symmetry requirements  Whose costs?  Possible difference in technologies  Legacy customers  Preferences for corporate relatives

10 Universal service  Among the possible “definitions” are the following loosely-stated concepts:  Basic residential telephone service should be available to all regions of a country for a common, reasonable monthly fee.  Income and wealth levels should not be significant barriers.  Every village of a certain size should have at least one public telephone.  All local telephone providers should be able to interconnect to the national telephone network at reasonable rates.

11 ICX & USO Conclusion  The movement toward competition in telecommunications services has highlighted the linkage between interconnection fees and the funding of universal service.  Changes in one area affect the underlying economics of the other.  One approach is to move interconnection fees toward becoming increasingly cost-based and to make the funding of universal service obligations more explicit.  While it is important to get the prices “right,” it is probably even more important to have the rules clear and fairly enforced.

12 What is driving convergence?  Parallel, (mostly) ubiquitous networks  Telephone, cable TV, wireless  Digital technology (not always)  Important to distinguish between digitized content and digital signaling  “Religious belief” in competition & de-regulation (?)  Key question: What is to be converged?  Telephony/cable television  Wired/wireless  Broadcast/common carriage  Circuit-switched & packet-switched networks

13 Alternate regulatory approaches  Wait until competition, however defined, is well established  Get out of the way early (leaving things to the anti-monopoly authorities)  “Bright-line” tests of market share  How is the market define?  Rely on case-by-case judgment of regulators

15 Mobile-to-fixed, fixed-to-mobile, and mobile-to-mobile in Israel

16 Free entry and negotiated interconnection in Sweden

17 The entry of competition for international calls in Israel

18 Calls to the Internet in the U.S. Recent FCC decisions are phasing out these payments

19 Financing the USO and current tariffs in India The Government is committed to provide access to all people for basic telecom services at affordable and reasonable prices. The Government seeks to achieve the following universal service objectives: Provide voice and low speed data service to the balance 2.9 lakh [290,000] uncovered villages in the country by the year 2002 Achieve Internet access to all district head quarters by the year 2000 Achieve telephone on demand in urban and rural areas by 2002 The resources for meeting the USO would be raised through a ‘universal access levy’ which would be a percentage of the revenue earned by all the operators under various licenses. --New Telecom Policy of 1999
