A 1000 users on a DS3 is WAY below what any ISP is over-subscribing a connection at today. The standard is 4000 users on a DS3 unless there is no cap. 4000 dsl users on a DS3 is easy, cable would be lower than that due to the higher speeds of the end users for the most part. I had 2800 DSL users on a DS3, all were SDSL or IDSL, lots at 1.5 x 1.5 and the DS3 never peaked over 18 megs. Where is the packet loss occuring? Between you and the gateway, or beyond.
