The Direct Station Selection (DSS) feature provides a user access to multiple functions for a given internal DN by using a single key (DSS key) with associated status indication. On OpenStage endpoints, DSS keys that can initiate direct calls and have feature override capabilities are known as DSS-direct (DSS-D) keys.
Both types of DSS keys function within the user's business group, and not between business groups.
For OpenStage and optiPoint keyset telephones, the administrator programs DSS/DSS-D destinations. Users cannot program them locally at their telephones because the administrator must create a line key to allow this type of operation.
For the optiClient 130 S, DSS keys are configured in the endpoint. Refer to the optiClient 130 S, Administrator Documentation and Operating Instructions for more information.
Depending on the endpoint type and its configuration per line key:
A DSS key initiates a basic call, which is treated as a normal A-B call.
A DSS-D key initiates a direct call, which overrides redirection at the call destination.
Both types of keys can be used to:
Show status of the destination associated with the key (idle, busy, or ringing)
Pick up a ringing call
Initiate a call by pressing the applicable key
Initiate a consultation call
The telephone does not audibly alert; instead, the DSS LED provides the following displays:
Off: The associated line is idle. Note:
On: The associated line has a call in progress or on hold.
Flashing: The associated line is ringing.
The DSS LED reflects the status of the line (DN) programmed for the DSS/ DSS-D key, not the status of the user associated with the prime DN device.
A blinking DSS/DSS-D key at subscriber A's phone indicates an incoming call for another subscriber (subscriber B) with the same key appearance. When subscriber A presses the key, the call is forwarded to the prime line of subscriber B, and subscriber B is connected to the call. The keyset rejects the forwarding attempt if subscriber B's prime line is busy.
Up to nine DSS keys can be assigned to a single device. For OpenStage endpoints, a total of 15 DSS and DSS-D keys can be assigned.
