Dedicated Internet Access means that the specified amount of bandwidth sold has been carved out and dedicated for your use. The type of DIA circuit your company needs depends on the circuit types available at your address and the bandwidth your company requires. There are plenty of benefits in using DIA like for example with Dedicated Internet Access, your company is guaranteed to receive the bandwidth you purchased, 100% of the time. If your company purchases a 200M Dedicated Internet Access circuit, both your download and upload speed/bandwidth are always guaranteed at 200M. DIA also includes service level agreement or SLA, which will guarantee network uptime and more. Dedicated Internet Access circuits almost always come with a significantly better guaranteed response time than inexpensive, shared business Internet connections. If you ask me, if you are running a business everyone knows that at certain times of the day traffic becomes congested, but when you have DIA you will be traveling at exactly the speed you were guaranteed.
