What is Symmetrical DSL?
Symmetric DSL (SDSL) also called symmetric digital subscriber line, is a growing broadband Internet technology that allows more data to be sent as well as received through common landline telephone lines. Whereas ASDL stands for asymmetric digital subscriber line and supports a faster download speed than an upload speed, a symmetrical digital subscriber line usually offers the same speeds for downloading as it does for uploading.
Most broadband Internet users today that have installed an ADSL connection usually have about 2 to 4 Mbps download speed and only 128 to 256kbps upload speed. SDSL effectively makes your connection faster by offering you the same download speed as upload speed, in this case 2 to 4 Mbps.
It should be noted that SDSL technology is primarily being developed in European markets. For most computer users in America, it is more than likely that the only DSL product offered is ADSL.
While the extra speed of uploading data is much appreciated, SDSL does have certain disadvantages compared to ADSL. The first is that SDSL must run on its own cable and can not co-exist on a voice service line. This means that a second line into your home must be installed, one for your landline telephone and the second for just your broadband Internet connection. The second disadvantage is that SDSL is usually much more costly and thus usually focused on the business market where higher upload speeds are desirable.
