7.5 Internet-Based Connectivity
7.5.1 Internet-Based Connectivity Options
Modern WAN connectivity options do not end with Ethernet WAN and MPLS.
7.5.2 DSL Technology
A Digital Subscriber Line (DSL) is a high-speed, always-on, connection technology that uses existing twisted-pair telephone lines to provide IP services to users.
7.5.3 DSL Connections
Service providers deploy DSL connections in the local loop
7.5.4 DSL and PPP
ISPs still use PPP as the Layer 2 protocol for broadband DSL connections because of the following factors:
PPP can be used to authenticate the subscriber.
PPP can assign a public IPv4 address to the subscriber
PPP provides link-quality management features.
Host with PPPoE Client
Router PPPoE Client
7.5.5 Cable Technology
Cable technology is a high-speed always-on connection technology that uses a coaxial cable from the cable company to provide IP services to users.
