Broadband & Internet
High speed internet from JSR Technology
Dedicated high speed connections were traditionally very expensive items, the Broadband service is in effect a large cooperative system, where the connectivity is centrally purchased and then shared amongst a high number of users (contention) on a best efforts basis. Broadband is the collective name and your actual connection to the network could be via different technologies, your connection options will depend upon your location.
By sharing the capacity users can all get a slice of the high capacity data network delivered by various technologies including:- ADSL/ADSL2+, Annex M, Fibre to the Cabinet (FTTC) or Fibre to the Premises (FTTP).
ADSL & SDSL
With speeds of up to 8Mb/s download and 832Kb/s upload (asymmetric) on ADSL and 2Mb/s symmetric for SDSL this is the first and traditional broadband access technology. Available in the majority of the UK.
ADSL2+ and Annex M
With speeds of up to 20Mb/s download and 2.5Mb/s upload this series of products replaces the traditional 20CN technologies and offers more flexibility, higher speeds and better pricing.
FTTC (Fibre to the Cabinet) & FTTP (Fibre to the Premises)
Speeds of up to 100Mb/s Download for FTTP or 40Mb/s for FTTC and 10Mb/s Upload are available with the latest generation of access products. With rollout of FTTC now underway and FTTP in trial Internet access is really accelerating and evolving allowing much richer content and more innovative services to be used.
Bonded Internet
High Speed, High Resiliency, Supports VoIP & Video Conferencing, Get leased Line standard connections for a fraction of the cost.
Put simply, Bonded ADSL or SDSL (collectively DSL) is where multiple broadband lines are joined together to form a single larger pipe. The industry standard way of achieving this is through the use of MultiLink PPP (MLPPP). This is a tried and tested technology and has been used by Internet Service Providers for many years. It is the very same technology used to provide ISDN internet connections larger than 64k. Whereas with ISDN multiple 64k channels could be combined to make a larger (128k or 256k) connection, with DSL we are combining multiple high-speed ADSL or SDSL lines.
Ordinary consumer ADSL and SDSL routers are not capable of bonding DSL lines. A more sophisticated router such as Cisco or FireRack is required to perform line bonding. Some Virtual Internet Service Providers (VISPs) claim to provide a bonded DSL service without utilising MLPPP. Typically the technique that they use is to bond multiple VPN connections together, rather than bonding multiple DSL lines. This is not true line bonding and is a technically inferior solution with a number of disadvantages.
