Internet Bandwidth Requirements

Internet connectivity is required. The number of users and the other network traffic will determine the final amount of bandwidth needed.

     Active users per office Internet tunnel
     Smart Client Download  700 Kb/s  3.5 Mb/s 7 Mb/s 14 Mb/s 35 Mb/s 70 Mb/s 350 Mb/s
     Application Load on firm bandwidth   3.5 Mb/s    18 Mb/s    35.28 Mb/s    71 Mb/s    176 Mb/s    353 Mb/s    1764 Mb/s  


    • Kb/s = Kilobits per second; Mb/s = Megabits per second
    • The above bandwidth listings are guidelines for general use of CCH Axcess products. For a product such as CCH Axcess Document you will need to look at upload speeds as well. For example if you have 20 users all uploading files at the same time you will need enough upload bandwidth to handle that.
    • Customer bandwidth may also vary based on the network latency and equipment, Internet peering issues, bandwidth at upstream providers, Internet usage besides CCH Axcess, etc. These variables affect the perceived performance of the connection and the amount of bandwidth required to keep performance adequate.
