What speed is DSL
DSL is the abbreviated word for Digital Subscriber line, Digital subscriber line or DSL works off a DSLAM or Digital Subscriber Line Access Multiplexer which server as an interface device connecting from your location to the DSL providers closest network aggregation point, commonly a Central Office. DSL speed is affected by the wire feet distance from your location to the underlying providers DSLAM. DSL providers require a DSL modem installed on your premises.
Distance is measured in feet and up to 20,000 feet or 4 miles from the DSLAM (typically located in a Central Office).
How fast is your DSL?:
20,000 feet would produce approximate bandwidth 128kbps upload, 384Kbps download.
15,000 feet would produce approximate bandwidth 256k upload, 768kbps download.
10,000 feet would produce approximate bandwidth 400k upload, 1.1Mbps-2Mbps download.
5,000 feet would produce approximate bandwidth 500-768k upload, 3M-5Mbps download.
1,000 feet would produce approximate bandwidth 768k-1Mbps upload, 5M-7Mbps download.
* Distances and speeds are estimated. Actual distance varies and is determined by actual wire feet.
DSL is best used for residential or a web surfer, as the downstream is much faster than the out or upstream.
DSL is also prone to more technical glitches than T1 and has a lower priority of repair for the carrier.
We recommend purchasing DSL through your Global IT representative, or going direct and using the local provider in your area for DSL. The local provider will offer the best QOS and customer service compared to competitors.
DSL does not offer service level agreements (standard of services) so it is a best guess effort.
You can receive static IP’s with DSL.
