DSL - Overview
Digital subscriber line technology is a copper loop transmission technology , which solves bottleneck issues often associated with the last mile between network and service providers.
While DSL technology offers dramatic improvements in speed (up to 8 Mbps or more) over other methods of network access, the real strength of DSL service opportunities lies in actions such as -
- Multimedia applications required by users of today's network.
- Performance and reliability.
As the following comparison table example shows, DSL services provide performance advantages for network service users over other methods of service. 'network access. In addition, DSL services extend theseoperational improvements for public and private operators (Campus).
One of theIndisputable advantages of DSL technology is that it is the NSP and helps service users to take full advantage of existing infrastructure, layer two and layer three protocols (such as Frame Relay, ATM and IP) , and have reliable network services already entrusted to come.
DSL can easily support advanced business class services such as Voice over DSL (VoDSL) and new variants of proven and well understood technologies such as Frame Relay over DSL (FRoDSL). The latest generation of DSL equipment also offers end-to-end Service Level Management (SLM). For simplicity, in our discussion of business class DSL applications, we'll group all of them under a new acronym - SLM-DSL .
