information about the call associated with the key. If the call is the currently active call, the duration of the display is determined by the switching system. If the call is a background call. the terminal will display the information for 5 seconds.

Group Pickup

Group Pickup is a switch-based feature that allows you to answer a call that is ringing on any of the phones in a group of phones that have been listed with your telephone operating company as a pickup group. If your Optiset terminal is subscribed to this feature, it is available through the menu display when you go off-hook. When you hear a phone in your pickup group ringing. simply go off­ hook and press the t/ dialog key to answer the call.

Note: Group Pickup ceases to be available as soon as you begin dialing an out-going call.

Hold

Hold is a combined local/switch-based feature that is used to put either a single party or a conference on hold so you can answer or make another call. The feature can be activated either by pressing the Hold feature key or by selecting the Hold? menu option from the menu display. Either action sends a Hold request to the central­ office SWitching system.

When a Hold Acknowledge is received from the switching system, the Optiset terminal will isolate the call from the terminal's acoustic circuits, and the Hold status light will turn on. If the Hold request is rejected by the switching system, the current call state of the terminal will not change, and an error message may be sent to the terminal by the switching system.

For non-EKTS calls, the line key status light indicates that a particular call is on hold. For EKTS calls, the line key status light indicates "that the call is on hold in the entire EKTS group. This condition must be recognized and acknowledged by the switching system before the Optiset terminal will cause the line key status light to give the Hold indication.
