Date posted: 11/3/98 QUESTION Here's my system:
How can I be sure that the K56 modem that's installed in my PC is upgraded to the fastest V.90 standard? I can't connect faster than 28.8 bps. --Jim W ANSWER Your connection problems may be caused by your phone line and not your modem. To connect properly at 56K, you need to meet all of these conditions:
So, the first thing I’d do would be to make sure you are calling a 56K POP at your ISP that is compatible with your modem. Next, test your line by having a friend stop by with their computer and dial a 56K connection, or call a 56K test number. Some modem manufacturers, such as 3Com, provide toll numbers you can call to see whether your phone line is 56K capable. If the phone line isn’t capable, you can either try getting a new line or complaining to your phone company. Sometimes phone companies will use digital splitters to split a 64K line into two lines that will only support 28.8. Other times you may not live close enough to your phone company to keep up the 56K. So, about V.90. Check with whom you bought the modem from to see if it’s a V.90. If not, some modems can be upgraded to V.90, others cannot. I have an X2 modem in my machine that won’t accept a V.90 upgrade. You’ve got to check with the manufacturer of the modem. Usually, you can download an upgrade program and it will tell you whether your modem is upgradeable or not, or whether it is already V.90. Results may vary. I wish I had simpler answers, but thus is the state of V.90.
