  1. IEEE ICC 2002 A MODERN PUBLIC TELECOM PLATFORM A Unified Payphone and Internet Access Solution Antonio Carlos Bordeaux Rego April 2002

  2. Challenges to Brazilian Telecommunications • To increase access to telecommunications services, specially basic telephony, for low income population • To develop globally competitive technology, but, at the same time, adequate to Brazilian socioeconomic situation • Case:A Modern Public Telecom Platform developed by CPqD - Same solution for payphone and Internet Access

  3. Drawbacks in traditional coin fed payphones High expenses OAM Vandalism and stealing Coin collecting Loosing Business Low Teledensity (1,5 payphones per 1000 inhabitants) Public Payphone Issues

  4. Public Payphone Solution • Proposal: Card Based System • Requirements • Low cost OAM • Easy to use for low income population • High immunity to forgery and vandalism • Local and long distance call from the same terminal • CPqD solution Develop New Inductive Card Technology Platform

  5. Inductive Card Platform • System Components • Inductive Card • Payphone Terminal • Remote Supervision & Management System – SSR • Mechanism: magnetic induction • Inductive Card • It is made of 100 passive microcircuits, each one connected to a fuse • Operation senses the fuse • Open: credit not valid • Short: credit valid • Dt Burn: credit vanish

  6. Inductive Card Platform • Inductive Card Features • Contactless inductive mechanism. • Easy to use: can be inserted in any position. • High immunity to moisture, dust, heat, UV, X-ray, EMF, etc. • Low production cost in large quantity (~ US$0.10 per card). • Internal codification identify each service provider, issuer, manufacturer, etc. • Extra revenue: advertising on both sides.

  7. Inductive Card Platform • Payphone Terminal • Power-fed by telephone line • All electronic: microprocessor based • Low cost (about US$300.00) • Very low demand for maintenance • Contactless static reader – no mechanical moving parts • Compatible with existing network and easy to install

  8. Inductive Card Platform • SSR – Remote Supervision and Management System • Management of up to 32,000 payphones terminals • Constant monitoring of operational conditions • Supervision of self collect payphone tables • Flexible: configuration according to operator needs • Easy corporate systems interoperability • Scalable: new features addition with customized modules • Multiuser: Client/Server architecture

  10. Public Payphones Location • Universalization Targets • Anatel (Brazilian Regulatory Agency) Rules • These rules require that users should not have to walk more than a certain distance to find a payphone terminal, and also to find a reseller of pay phone cards . • Where is the best payphonesplacement? • Management Tool: SAGRE TUP This module manages the payphones placements, assuring compliance with regulatory requirements.

  11. SAGRE: Competitive SW Technology • SAGRE is a set of applications, developed and supported by CPqD, to manage the outside plant and automate the network planning process, based on Vision* GIS and Oracle • Functions assisted by SAGRE • Outside Plant Registration and Urban Mapping • Outside Plant Network Planning • Market Analysis for Outside Plant Network Planning • Management: Engineering, Deployment, Facilities Inventory and Maintenance • Business Impact • 14 million fixed lines (50%..) and 2 million mobile lines (20% Brazilian lines) • 9 Telecom Operators (Telefonica, Telemar, Brasiltelecom, Embratel and others)

  12. Inductive Card Platform Achievements • Profitability per payphone terminal • 1991 : US$500 revenue per year / US$520 cost per year • 2001 : US$400 revenue per month / US$50 cost per month • Inductive Card payphones deployment • 1991: Coin technology/ 236,000 terminals • 2001: Card technology/ 1,5 million terminals • Monthly production – cards • 60 million • Business impact • Five companies manufacturing payphones terminals Daruma, Icatel, Siemens, Ericsson, Splice • Five companies manufacturing inductive cards Thomas de La Rue, CMB, Interprint, CSM, ICE • International business • Bolivia

  13. Internet Service Public Providers Access . . . Network Value- Added Services Future:PublicAccess to Internet • Public Access to Internet is the technology which provides managed IP access to VAS (e.g. ISP) through multiservice terminals equipped with inductive card reader as a prepaid way of collection • Service Access Manager(OAM): dotIP • Manage subscribers IP “sessions” to value-added services (VAS) such as ISPs • Control and superviseusers’ credit consumptionfrom inductive card
