  Hello,
  

  
  I've been searching around the web for how many bits p/s are transfered max for Cable and ADSL connections at their various connection levels but havent got very far. Does anyone know of a site that specifies this?
  

  
  So far I've got modems and Tx connections:
  

  
         Dialup144Kbps = 1800, // 14400 Bits * 8 =  Bytes
         Dialup288Kbps = 3600, // 28800
         Dialup336Kbps = 4200, // 33600
         Dialup566Kbps = 7075, // 56600
         ISDN64Kbps = 8192, // 65536
         T1 = 19300, // 154400
         T2 = 787500, // 6300000
         T3 = 5593250, // 44746000
         T4 = 34272000 // 274176000
  

  
  the value after the equals is in bytes and in the comments is bits... I'm after any more ISDN connection speeds, cable speed and all the ADSL speeds... I can guess them but they need to be accurate (for documentation)
  

  
  thanks

  Try this site - it works out speed of your line and shows comparison with ASDL IDSN, etc

  Don't forget ADSL speed is assymetrical - upload and download speeds are differnt.
  

  
  Also you can run ISDN over two channels at 128 kbs
  

  
  Hope this helps
