Symmetric Digital Subscriber Line (SDSL)

Consider getting Symmetric Digital Subscriber Line (SDSL) service as an alternative to T1 service. Do you need both upstream and downstream speed to be the same? Do you run a small or medium business that runs a VPN (virtual private network) or terminal server? Do you need just a dedicated line that transmits data, and not voice? Then you should take a serious look at getting a symmetric high speed digital subscriber line.

A symmetric high speed digital subscriber line costs less than a T1 line. T1 lines are no doubt faster when it comes to transmitting data, but they will cost you hundreds of dollars more per month. Here are things to do to get a symmetric digital subscriber line:

1. Sign up with a SDSL provider.

2. Know what installation plan your SDSL provider offers.

3. Get reliable technical support from your SDSL provider.
