Internet leased lines are right for businesses that run critical applications and have to be up round the clock. Leased lines assure round the clock access to the internet with SLA. Faster upstreams are possible with this service that may not be available with a regular broadband connectivity. Another advantage is that bandwidth monitoring can be done on a real time basis. The line is always active unlike a dial-up connection. This is an exclusive connection unlike broadband that comes with a dedicated bandwidth. Components like routers and local loop circuit or black haul circuit are used to link to the service provider.
