  1. DSL Services: Deployment and Economics The EgyNet Experience Ahmad Khaled Sallam asallam@egynet.com.eg Network Planning Manager EgyNet

  2. Agenda • EgyNet background. • DSL-Network Design • ATM core • DSL Setup • DSL-Network Cost Structure • DSL Value Added Services • FR over DSL • Voice over DSL • Issues with the unbundling • IAD’s • Targeted Markets. • Provisioning Processes.

  3. EgyNet • Data Operator and Class A ISP, operational since March 2000. • The first PDN in Egypt under private sector management. • Started with 44 PoPs now 155 PoPs. • 18,000 installed DSL-port. • 3,500+ installed connections (FR, SDSL & ADSL) • 12,000 dialup ports. • Prime provider of connectivity and DSL services in Egypt. • Major customers include: • Corporate: National Bank of Egypt, Cairo Bank, Sales Tax Authority & Social Insurance. • ISP’s: Internet Egypt, Misr Net, LinkDotNet & Soficom.

  4. ATM core • 25 Lucent CBX-500 Switches • Redundant Power Supplies, Processors, redundant cards • E3 Trunks. • Alternative routes.

  5. Copper Line Internet Gateway Local Directors Aggregation and/or BRAS 45 Large DSLAMs + 100 small DSLAMs Cache Server(s) DSL Network Setup 25 Core ATM Switches Internet

  6. VPN Residential DSL Business DSL Business DSL VPN VPN Conceptual Residential Volumes ATM & DSL Infrastructure Connectivity Internet VPN Business

  7. DSL Cost Structure • Excluded • CPE • :ocal loop

  8. ADSL users behavior • ADSL users tend to use their connection almost 24 x 7

  9. Splitters cost and ownership • The PTT is reluctant and/or slow to install splitter chassis. • If DSL operator pays for splitter chassis, the the PTT looses control of the copper consequently the tel line. • Various DSL operators will have various splitter frames. • large hidden cost associated with installing the splitter chassis (cabling, space, support) ATM Network DSLAM ADSL modem Copper Line Home Filter Splitter Chassis Voice Switch Voice PSTN

  10. A Different Approach • IAD’s are CPE’s with Ethernet and POTS interfaces. • Computers connect to Ethernet and tel. Handsets connect to POTS interface • Voice and data are carried over ATM. • Data is carried to its destination over the ATM network • Voice is carried over ATM to a Voice gateway that connect to the voice switch over a V5.2 interface. • No extra cabling, no splitters Voice PSTN ATM Network IAD V5.2 Ethernet Copper Line POTS Voice G/W Voice Switch DSLAM

  11. FR over DSL • FR-ATM Conversion performed inside CPE not CO switch. • ATM VPI/VCI’s are converted to FR DLCI’s. • Better cost / FR port. • Allows for high density/density of FR deployment per CO. 25 Core ATM Switches V35 V35 Copper Line CPE FR5-FR8 CPE FR5-FR8 Router Router DSLAM DSLAM FR FR ATM

  12. Copper Local loop Copper Local loop Stinger DSLAM Stinger DSLAM LAN LAN EtherConnect Service EgyNet ATM/FR • L2 connectivity service with no IP component • Meant to augment FR not to cannibalize it. • DSL-router CPE with 4 Ethernet ports. • Ideal for basic IP connectivity for ATM machines or small branches 25 Core ATM Switches

  13. Services Growth

  14. CONTENT VPN Residential DSL Residential DSL Business DSL VPN Business DSL Business DSL VPN VPN Conceptual • Best value when large volumes are associated with good margins. • Residential services has to grow away from Internet (Int’l BW) • The buzz word is CONTENT. • Content includes: • Gaming • Video, Audio conferencing • Voice over DSL. • Media streaming. • Local portals Residential Volumes ATM & DSL Infrastructure Internet Margins Connectivity VPN Business
