Matrix PRASAR UCS System Manual 861
These keys are programmable. However, as you cannot change the labels avoid programming these keys.
For instructions on programming these keys, see “DSS Key Settings” under “Configuring Matrix SPARSH VP310”.
A few of these Feature keys are equipped with an LED to indicate the status of the feature assigned to it. You may
re-assign other features to these keys. We recommend you to assign those features that require LED indication to
the Feature keys equipped with an LED.
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 feature 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 Feature key
to which the Auto Redial feature has been assigned will glow Blue, when Auto-Redial is set, and the LED is turned
off when the feature is canceled.
Direct Station Selection (DSS) Keys
These are 12 programmable keys that can be assigned to Stations and Trunks and important or frequently
accessed features of PRASAR UCS.
For instructions on programming these keys, see “DSS Key Settings” under “Configuring Matrix SPARSH VP310”.
DSS Key LEDs
Each DSS key is equipped with an LED which glows to indicate the status of the Trunk/Extension or Feature
assigned to it.
• Status of Extensions and Trunks: The LED of DSS keys assigned to Extensions/Trunks glow in three
colors to indicate status of the call event on the Extensions/Trunks and on the Extended IP Phone.
Thus, the status of the Extended IP Phone user's own Extension as well as that of the other Extensions
and the status of Trunk lines are indicated by the LED of the DSS keys assigned to those Extensions and
Trunks on the Extended IP Phone.
