Table: Nstl Ratings Of Modems And Modem Cards

Here are the results of testing on several external and PC Card (PCMCIA) 
      fax/modems by NSTL, a unit of The McGraw-Hill Companies Inc. All of the modems 
      can transfer data at 28.8 kilobytes per second (Kbps). Nearly all are based on 
      the V.34 specification ratified last year by the International 
      Telecommunications Union (ITU). The V.34 modems "probe" the phone line and 
      assess its capabilities and quality. The modems figure out the maximum speed 
      the line will tolerate for error-free transmission and adjust the rate up or 
      down as warranted.
      
      The accompanying tables rate the modems on how accurately and rapidly they 
      transfer data under various conditions, how easy they are to use, what features 
      they offer, and on other variables. The results are compiled into an overall 
      score, where 10 is the top score possible. The prices are the manufacturers' 
      suggested prices at the time of testing. Street prices are likely to be much 
      lower.
