862 Matrix PRASAR UCS System Manual
The following table shows the relationship between the color of the LED and various events:
• Blue indicates the state of the extension/trunk you access. For example, when you make a call to
another Extension 203, the LED of the DSS key assigned to Extension 203 blinks Blue to indicate
ringing at the Extension. If you have successfully established speech with Extension 203 the LED
glows Blue continuously.
• Red indicates the state of other Extensions/Trunks. For example, if the LED of the DSS key assigned
to Extension 201 is glowing Red continuously, it means Extension 201 is busy with another Extension
or Trunk.
• Violet indicates the state of the trunk you are in speech with. For example, when you are in speech on
an outgoing call on Trunk 1 the LED of the DSS Key assigned to Trunk 1 will be continuously ON.
When you put the call on hold, the LED will blink slowly.
• Status of Features: The LED of a DSS key is activated when the feature assigned to this key is used.
Not all features require LED indication. For example, the feature Call Pick-Up does not require an LED. So
when you assign this feature to a DSS key, the LED of the key remains inactive, when Call Pick-Up is
accessed.
Feature like Auto Redial requires an LED to show that it has been set or canceled. So, the LED of the DSS
key to which the Auto Redial feature has been assigned will glow Red, when Auto Redial is set, and the
LED is turned off when the feature is canceled.
The LEDs of the Call Appearance (CA) Keys will function in the same manner as the DSS Key LEDs.
Dial Pad
The dial pad consists of 12 fixed keys for the digits 0-9, and the characters * and #. The dial pad is used for dialing
numbers of extensions, external parties, and for dialing the programming and feature access codes.
Speaker Key
The speaker key sets the phone in 'Speaker mode' for hands-free operation.
