56K Connection Speed FAQ
Not getting full 56K connection speeds? Well, first of all, FCC regulations only allow for about 53000 bps connection speeds. But if you're still not getting any better than 28.8 connection speeds with a fully V.90 compliant modem, you may want to read the following
3 things you need to get 56k speeds:
1. A 56K modem
2. An Internet service provider that supports 56K (We do)
3. A phone line that supports 56K
#1 The first one is easy. There are plenty of 56K modems on the market, with more arriving every day. We recommend 3Com Sportsters because they are the best at handling the less-than-perfect phone lines in Southern Maryland. You can buy this brand and many others at Performance PCs in Dunkirk
#2Chesapeake.Net has all 56k Modems as identified on our contact page . Our modems are monitored continously. They will connect to your modem at the highest speed possible given the quality of your phone line.
#3 The third requirement is most typically the reason that will prevent most people from using 56K. For 56K technology to work, there can only be one analog-to-digital conversion (A/D switch) between your home or office and the Closest Phone Company Central Office (CO). If there's more than one, you can't use 56K, and your connection will be limited to V.34 speeds (a maxumim of 33.6K but 26.4K is more common). This is not a condition that your ISP can take care of. Most likely if there are more than one A/D switches on your line, you are stuck with it. It is a method used by the phone companies to add more phone lines to a given area by creating branch points in existing phone lines. Its fine for voice-grade connections but immediately rules out any hope for a fast modem connection.
To find out if your phone line supports 56k connections, 3Com/U.S. Robotics has a test line that allows you to dial in with your existing V.34 or 56k modem. The phone number to call and other details can be found at the page below . 3Com strongly recommends calling the test line multiple times to get an accurate reading.
If your phone line passes that test, you can probably use a 56K modem. It isn't guaranteed, though. The long distance call to the U.S. Robotics test line may be routed through different circuits than a call to your local ISP. The only 100% guaranteed test is to borrow a 56K modem and dial into your local ISP from your home or office. If you can't connect to a known 56k ISP, then your lines do not support 56k connections
