DSL Digital Subscriber
Line is a generic name for digital lines that are provided by telephone
companies to their local subscribers and carry data at high
speeds.
Why would you want DSL as your Internet connection?
- DSL offers a fast connection. Rather than wait hours for a document
to download using dial up, with DSL you can download large files in just
minutes.
- DSL allows you to use an open Internet connection and use your
telephone line for phone calls at the same time.
- DSL speed is typically a lot faster than a traditional modem and
doesn't require new wiring.
Disadvantages:
- DSL is designed provisioned to serve residential customers.
- Best effort service, you pay for service level that you might not
actually receive.
- Asymmetrical-faster download speeds than upload speeds, for most
businesses it is just as important to fast up as it is down...for
example when sending an email with a large attachment.
- No Service Level Agreements (SLA)- Class of service typically has
next
business day response at best. Your organization could be down for two
to three days.
