Page 4: Overview
Overview The Sage 925VST The Sage 925VST is the field component of the Sage Voice over Packet Test System (VTS). The 925VST initiates VoP service qualification and maintenance tests from a customer premise or any 2-wire or 4-wire access point to a Sage responder that is typically located in the central office. -
