I NTR ODUCTION 1-4 Networking Concepts ADSL Digital Subscriber Line (DSL) tec hnolog y transmits both data and v oice ov er ordinar y tele phone lines . Signals above 4 kHz are cut off in nor mal telephone communications as noise, so DSL uses this spectr um to transmit data. Since Internet users and people telecommuting from home normally download [...]

N ETWORKING C ONCEPTS 1-5 Data flows are broken up into fixed length cells , each of which contains a Virtual Pa th Identifier (VPI) that identifies the path betw een two nodes , and a Vir tual Ci rcuit Identifi er (VCI) that identifies the data channel within that virtual path. Each virtual ci rcuit maintains a constant flow of cells between the t[...]

I NTR ODUCTION 1-6 Routing If A TM Protocol Encapsulation is set for PPP/A TM or IP/ATM, the router will forward incoming IP packets and use RIP 2 for routing path management if enabled.
