Specifications 5-7 VisuaLink 128/384 General Description Operating Modes & Features The following provides a summary of the main operating modes and features for VisuaLink. VisuaLink Unit Control VisuaLink can be controlled by one of three devices: • VisuaLink Wireless Infrared Remote Control • VoicePoint+ or Analog Phone Set (connected to TEL jack) • Personal Computer (connected to Serial Port) A buzzer is built into VisuaLink, and will sound when an incoming call is detected. When using a VoicePoint+ or analog phone, their respective ringers will indicate an incoming call. Call Dialing (Originating) Modes • Direct dial calling (by the Remote Control, PC control, analog telephone, and VoicePoint+) • Speed-Dial calling (by the Remote Control, PC control) • Redial calling (by the Remote Control, PC control) VisuaLink provides 130 speed dial number address book for call originating For redial, 30 numbers are automatically saved for both incoming and outgoing calls. VisuaLink can be set to only originate a call and can reject the originating call that does not meet the specific condition. (Originating number filter feature) Example conditions are: • Incoming call only • Inhibits originating a call to the number other than the registered abbreviated dial numbers, • Inhibits originating a call to special number (for example, the number starting from 001). Incoming Call Answer Modes • Manual • Automatic • Selective Selective is a security mode, and will automatically reject an incoming call from phone numbers other than those in the abbreviated dial list.)
5-8 Specifications VisuaLink 128/384 General Description Line Interface Control Originate at a 64 Kbps or 56 Kbps to the North American National ISDN-1. Line Connect Modes • BRI interface with VisuaLink 128/384 and other ISDN equipment (TA, FAX, etc.). • Selects an incoming call in a sub address setting Video Display/Output Modes Display Picture-in-Picture (PIP): • 1/9 transmission video display (mirror display) • 4-position selection is possible. (can be positioned in any of the 4 quads of the TV screen) Video Output: • Preview image • Far-site image • Still picture (snap shot picture: 720x480) On-Screen Menus display settings for line connection, conference control, and speed dialing. A display pointer can be displayed on the local and remote monitor via the IR remote Audio Control Modes • Control of output volume • Transmission audio delay • Manual selection of lip sync • Microphone muting • Audio input selection Audio input is switchable between telephone, headset and audio input mixed with microphone input. The audio input from a VCR, or other playback source, can be mixed with the microphone audio and transmitted to the distant end. The received audio can also be mixed. Data Conference A data conference can be held simultaneously with a videoconference using data conference application software (sold separately). This requires use of a personal computer.
Specifications 5-9 VisuaLink 128/384 General Description Multi-Point Conference Control Multi-Point Conference Modes: •Audio Switch • Chairman mode (Video selection, local room transmission, multiple address, remote camera control, pointer control, still picture transmission, remote camera switch) • Selective Receive (Video selection, local room transmission) Multi-point conference control protocol. • ITU-T Recommendation H.243 (International Standard Method using LSD) • NEC own method (NECs own method using MLP) Camera Control Switching modes: • VisuaLink Remote Control (Local/remote camera control (camera switch, pan/tilt/zoom/preset) • PC software (sold separately) can control a local camera (near end) and remote camera (far end). • Speaker detecting. It detects a speaker from the connected microphones (one of three) and automatically switches to the stored preset for that speaker. Selection for camera type: •VC-C1 •EVI-D30 Remote camera protocol selection: • ITU-T Recommendation H.281 (International Standard Method using LSD) • NEC own method (NECs own method using MLP) Maintenance VisuaLink employs the following maintenance modes: • VisuaLink firmware can be manually or automatically downloaded from NEC. • Loopback diagnosis capability • Communication log (start date, complete date, duration, fee, reason for the disconnection) can be recorded and used by a PC.

A camera control is also assigned to either Serial 1 or 2. A camera control driver selects either VC-C1 or EVI-D30 camera types. If EVI-D30 is used, a maximum of two units can be controlled in cascade. (Some features may not be available in certain combinations of audio mode, LSD speed, and MLP speed.)
