ViewStation 512/MP

4.To select a calling speed, highlight the Speed Indicator Icon, press SELECT, then use the UP and DOWN arrow buttons to select a speed from the list that appears onscreen. The number of connected ISDN lines and the selections made on the Dialing Speeds screen will determine the speeds that are available. When you select a dialing speed of 2x56 or 2x64, the ViewStation will place a two-channel call at 112 or 128 Kb. If you select a dialing speed of 112 or 128, you will place a BONDING call at the selected speed. Your call may perform better with a 2x56 / 2x64 dialing speed than with a 112 / 128 Kb BONDING call.

Note that some calls can only connect using certain speeds due to far-site bandwidth limitations. Near-site configuration settings can also affect the speed settings available for making a call.

5.Press the SELECT button (or the CALL•HANG-UP button) to place the call.

6.As the call connection approaches completion, the circular call progress indicators on the lower left of the screen will change from blue to green. Two call progress indicators will appear for each available line.

If the call cannot connect, an error box will appear at the top center of the screen. You can redial from the Video Phone screen, where the number you entered will remain until it is replaced or the system is turned off.

When the call connects, the party you are calling will appear in the main window and near-site video will appear in a smaller window at the lower right. If you are using a dual-monitor configuration, the party you are calling will appear on the main monitor and you will appear on the second monitor. For information about controlling the cameras, see the Cameras and Sound section of this manual.
