Whoah. Are you sure you're saturating the DS1 and not the router? Do you
have numbers to back up moving to a DS3? How big is this company? I ran a
large ISP for a couple years, and I have never seen a non-content-provider
or ISP that needed a DS3.

Highly recommended tool: MRTG, the Multi-Router Traffic Grapher, which
polls SNMP devices and throws up nice graphs in HTML. You can find it at
