ISP Information:
A piece of hardware that you use to translate the digital data frames of a T1 line into a 10BaseT connection where Internet connectivity is concerned. If the T1 lines are used for voice connections, a CSU/DSU is required to translate the digital frames into signals that your office phone switch can interpret. Basically, the phone network/Internet consists of a bunch of CSU/DSUs talking to one another. When you lease a T1 ISP Glossary:

Below is the data my Courier external returned and according to modemsite I should be getting better connection speeds. I have never had the modem report anything better than a 28.8 connect. WinXp says the driver is Microsoft 5.1.2462.1 along with a reference to windows/system32/drivers/modem.sys. Here's the modem data, anyone got any ideas? Everything looks fine and I agree with what you learened at modemsite,you should be able to get a V.90 connection. What is the init string being used? You will find that in the modem log. And could I see the results of an ati7 query? SNR ( dB ) 36.6 kinda noisy for a USR, is the courier different?Not noisy at all. The higher the number, the better the ratio (the lessnoise compared to signal) It's not a real good indicator of things becausewhenever I force a V.34 connection, Iwill get SNRs around 35 or 36. But when I allow a V.90 connection, and getone, the SNR will be much higher (like around 50). So it's a littlesubjective, you have to look at the modulation used.--Hooda Gest"In a New York minute, everything can change..."
