This is from Avis's site. Satellite Link Quick Reference Guide:

The administrator system must be running Pro Tools HD with HD hardware (HDX, HD Native, or HD Core) and a SYNC peripheral (SYNC HD or SYNC I/O). Satellite systems do not require HD hardware or software, although functionality will be limited without it. For instance, you cannot start playback from a Satellite Pro Tools system that is not using an HD Playback Engine.
