T1’s were once considered fast. Relatively speaking that is no longer the case. Still, business bandwidth demands in certain areas are increasing faster than fiber is being trenched . That doesn’t mean you are stuck with a basic 1.54 Mbps of service when you really need 10 or 12 Mbps. T1’s can be bonded (NXT1) for service up to 12 Mbps. (DS3’s—sometimes referred to as a T3—are also an option offering speeds up to 45 Mbps.)
T1 lines usually come into your facility in the same bundle of installed telephone wire that brings in multi-line telephone service. Because it is ordinary telco wire, most business locations are already wired for service and enabled for T1. As a result, T1’s, or bonded T1’s, may be a plausible dedicated solution for your business at this time.
