SPECTRUM™ can be used over the Internet. It runs over the Internet through a direct connection or a Virtual Private Network (VPN).

A key feature is its fast text interface, which makes this a practical solution to practices with remote branches looking for cost effective real time systems.

AT's own mail server, the V-Box™, and web-based Vision® Information System (VIS) interfaces with SPECTRUM™ to produce a powerful combined information and management system.
