Residential IP Networking “Instant BroadBand” ver 4 December 2000

Original Voice Network Central Site Sub-Station Home Main Voice Switch Branch Voice Switch STM-1 POTS copper fiber Voice Original Voice Network

Problems at Home: Slow Data Communications Expensive Connection Central Site Sub-Station Home Main Voice Switch Branch STM-1 copper POTS fiber Modem Problems at Home: Slow Data Communications Expensive Connection No simultaneous use of phone Dial-Up Internet Access

Problems at Sub Station: Central Site Sub-Station Home Main Voice Switch Branch STM-1 copper POTS fiber Modem Problems at Sub Station: Switch Resources in continuous use Link to Central carrying analog data which is difficult to multiplex Dial-Up Internet Access

Problems at Central Site: Sub-Station Home Main Voice Switch Branch STM-1 copper POTS fiber Modem Problems at Central Site: Switch Resources in continuous use Link to Sub-Station carrying analog data which is difficult to multiplex Dial-Up Internet Access

Carrier / Operator Issues Central Site Sub-Station Home Main Voice Switch Branch STM-1 copper POTS fiber Modem Carrier / Operator Issues Expensive resources in use for lowest cost calls Loss of revenue from outgoing calls Loss of revenue from incoming calls Loss of Revenue from Centrex Services Dial-Up Internet Access

What Solution is the Service Provider Looking for... Parallel Data Network Time to market is critical - Fast Service deployment Minimal infrastructure additions / changes Proven Technology Simple to Install Meets Carrier h/w Requirements Meets Security Requirements Easy future upgrade to faster data rates Cost Effective !!!

xDSL Network Solution Central Site Sub-Station Home Data Internet Router Main Voice Switch Branch STM-1 Ethernet Switch ETH - xDSL Copper Splitter xDSL POTS copper xDSL Modem Data 10Base-T fiber 100Base-FX ETH xDSL Network Solution

Special Requirements from the Ethernet Switch Hardware DC Power Supplies Security Secure system that does not need the user to “ LOG ON” Bar all Port to Port Communications (except through Router) IP Intrusion Control Network Resources No Waste of IP Addresses Ethernet Switch

Security IP Intrusion Control Function Ensure that users access the system ONLY with a fixed IP Address (es). Limit access on a per port basis complying with this criteria Implementation Ethernet Switch contains table : Port - IP Address (es) Non-IP Data that reaches switch is discarded Data that reaches switch with invalid IP address is discarded and trap is generated

Is there an alternative ??? Use DSLAMs with an ATM backbone Compare the solutions: Cost Complexity Bandwidth Future - Proof
