This page describes the Vision design, emphasizing the features that let you customize the system for individual requirements, not only for the company or institution where the system is installed, but also for the people who use VisionPhones daily to perform their jobs. Both the VisionLS and VisionMS systems can be configured to provide all the advantages of key, hybrid, and PBX systems. These configurations can be used by themselves, mixed in one system, or even mixed on each station, with little or no changes to system hardware. For example, you can set up a customer site as a PBX system, with one department at the site configured as a key system and another as a hybrid system. With the Vision switch configured as a 1A2 key system, the user operates the VisionPhone like a 1A2 key telephone.
All telephone lines are visible on the telephone.
Users select the desired line by pushing one of the line keys. You answer an incoming call by simply pressing the blinking outside line key. You place an outgoing call by pressing an unlit outside line key, then dialing the desired number. The key configuration provides additional capabilities not usually found in key systems. Features such as inherent call privacy, transfer, conference, and call forward are all standard.
