1-2 Installation1.1 System FeaturesWhen a Panasonic Voice Processing System (KX-TVP50) is connected to the system, theycommunicate in a tightly integrated fashion using APT Integration. For example, when theVoice Processing System (VPS) executes Auto Configuration using Quick Setup (PCrequired) or using DIP switch initialisation (PC not required), the VPS reads data from thesystem to automatically create mailboxes for each extension and to set the VPS clock (dateand time).The system informs the VPS of the state of a call (busy, answered, ringing, disconnected, etc.)through APT Integration. The System also informs the VPS through APT Integration of thedestination of a call transferred to the VPS by the Call Forwarding or DISA Intercept Routing— No Answer feature. APT Integration is established after System Programs [130] and/or[131] have been set and after the VPS performs Quick Setup (or DIP switch initialisation).
