Why get DSL over T1?
DSL for businesses is one of the most cost effective internet connections you can get. Even though the bandwidth is negligible between DSL and T1, and the T1 generally has a more robust and offer more stringent SLA’s (service level agreements).
DSL has 99% uptime guarantees available.
Whereas T1 is 99.9%. This shows in the price.
Different types of DSL:
- ADSL (asynchronous): Allows different bandwidths both upstream and downstream. Also tend to be more residential.
- SDSL (synchronous): Allows the same bandwidths up and downstream. Also tends to be more robust, including more stringent SLA’s and includes a dedicated phone line.
