ADSL is available in bandwidths up to 24 Mbps downstream and 1 Mbps upstream, depending on the distance between your office and local exchange.


SDSL or Symmetric DSL is a type of DSL, which is ideally used for transferring VoIP telephony over your existing copper phone lines. The "symmetric" part of the term means that an SDSL connection has the same maximum upload and download speed. Available in bandwidths up to 2.3 Mbps, depending on the distance between your office and local exchange.

Bundled SDSL

If more bandwidth is needed than can be obtained using single DSL lines and your office is in an area where fibre optic is not available, it is possible to bundle multiple DSL lines into one virtual line to increase the bandwidth up to 20 Mbps, depending on the distance between your office and local exchange.


VDSL or Very high bit-rate DSL is the next generation DSL delivered over your existing copper phone lines. It is a fast growing broadband service that can be up to 3 times faster than standard ADSL broadband. VDSL is availble with a bandwidth up to 50 Mbps download and a maximum of 10 Mbps upload, depending on the distance between your office and local exchange.
