The easiest definition of SHDSL is Symmetrical Digital Subscriber Line. SHDSL provides a business Internet connection with increased bandwidth for both uploads and downloads. The most common type of ADSL Internet uses Asymmetric functionality and although it provides faster download speed upload speeds are much slower.
SHDSL subscribers typically experience upload and download speeds of 10Mb each with a standard copper or fibre telephone line contingent on the distance they are located from the exchange, whether the exchange is SHDSL enabled and the age and quality of the equipment being used for communication between the exchange and the locations of the subscribers.
At the present time copper offers speeds of 10mb/10mb, 4mb/4mb, 2mb/2mb and 1mb/1mb. While it s possible to subscribe to lower speeds, in cases where upload speed is critical, using business ADSL 2 Broadband with an upload speed of 1Mb is usually more cost effective.
Business Internet subscribers who are using SHDSL but lack the need to send data will not experience a decrease in the receipt of other types of incoming data transmissions (such as web browsing) like they would if they were using ADSL. This means subscribers who send 2mb files on a 2mb/2mb connection will notice a decrease a quarter in the time it would take for individual subscribers sent the same files on a connection with a 512k upload speed. If you send that same file on a connection with a 10mb/10mb speed, it would take 1/20th of the time. In addition SHDSL is capable of sending and receiving a variety of data simultaneously.
Contention ratios have a dramatic impact on the quality of SHDSL. The contention ratio refers to how many users are on the service at any given moment. You will find little or no contention among quality business Internet provider so low contention is defined as no more than 4 subscribers sharing the service. When there is no contention the services are provided for only one subscriber at any given moment and cost more because the costs are not shared by other subscribers. On the bright side subscribers do not need to share bandwidth with other subscribers.
SHDSL is most commonly used for IP telephone service such as VoIP that utilizes SIP trunks or Hosted PBX applications, web hosting and Email servers, video conferencing, transfer of large data files, LAN to LAN connections in corporations that might also include Virtual Private Networks and remote access for multiple users.
