What is the difference between SDSL and ADSL?
sDSL stands for Synchronous DSL, which simply means the download and upload speeds are synchronous (or in other words, equal). ADSL stands for Asynchronous DSL, this basically means that the download speed can be much higher than the upload speed. aDSL is the most common type of DSL, since faster downloads are usually the reason for getting a broadband connection.
With symmetrical DSL (SDSL), download and upload speeds are equal. With asymmetrical DSL (ADSL), download speeds are higher than upload speeds. Businesses with significant uploading activity–including large file transfers or emails, web hosting and document conferencing-are best served by an SDSL solution. SDSL also has the advantage of being a dedicated-line service and is supported by uptime and service-level guarantees.
