Direct Station Select

The following table describes the result of selecting a DSS or secretarial key for different host-set states and busy lamp indications. (For a list of sets that support this feature, see Feature-Phone Matrix.)

DSS Key Functionality
Host Set State	Monitored Device Call State
Host Set State	Idle	Busy	Ringing	Soft Held Call Recalling	Hard Held Call Recalling
Idle or dial tone, no calls on soft hold	Ringback	Busy tone	Call pickup & answered	Busy tone	Reorder tone
Talking, no calls on soft hold	Ringback (& release if secretarial)	Busy tone (& release if secretarial)	Ringback (& release if secretarial)	Busy tone (& release if secretarial)	Ringback or Busy tone (& release if secretarial)
Dial tone with call on soft hold	Ringback	Busy tone	Ringback or Busy tone	Busy tone	Ringback or Busy tone.

DSS Directed Call Pickup

When a DSS key is pressed during a ringing indication, the host set will perform a directed pickup of the call ringing the monitored device. A directed call pickup cannot be made if the host set has a call on soft hold. A directed call pickup cannot be made of soft hold or hard hold recalls to the monitored device.

Other Host-set Call States

DSS keys will be ignored in the following host-set call states:

talking with a third party on soft hold
listening to ringback tone while waiting for an answer
listening to a progression tone (busy or reorder)
listening to silence after dialing one or more digits
listening to dial tone to collect operand digits of a feature.

An example of the last scenario is if the feature access code for Call Forward Busy is entered and then a DSS key is pressed to program call forward busy to the DSS key's monitored device. The DSS key will be ignored.

DND on Monitored Devices

DSS calls to a monitored device in Do Not Disturb state will usually return DND tone. An idle host set is permitted to perform a Directed Call Pickup of a new call ringing a monitored set that is in DND.

Secretarial Transfer

A Secretarial Transfer capability is provided when a DSS key's line type is specified as "secretarial" in the Multiline Set Keys form. Pressing a DSS key with this option enabled will automatically transfer calls on soft hold to the associated device or directory number. The call can be camped-on to the monitored number if the number is busy. If the monitored device has call forward or call rerouting active and the System Option, BLF– CFA Indication Based on Set Enabled is set to Yes, pressing the DSS key will override forwarding (but not rerouting). The following scenarios illustrate behaviors associated with the secretarial transfer keys when the "BLF–CFA Indication Based on Set Enabled" System Option is turned on. In all scenarios the Boss is the monitored device and the secretary is the set hosting the secretarial transfer key.

Scenario #1	Boss is CFA to secretary causing the DSS/BLF key for the boss to flash on the secretary's set. Both boss and secretary sets are idle. Secretary presses the boss's DSS/BLF key. The boss's set rings, overriding CFA. Note: A standard (non-secretarial) DSS/BLF key is sufficient to provide one-touch overriding of call forwarding in this scenario because the DSS/BLF host (i.e., the secretary) is the forwarding destination. One-touch overriding from other sets requires the use a secretarial DSS/BLF key.
Scenario #2	The boss's DSS/BLF key is flashing on secretary's set. (Boss is CFA to Secretary.) Incoming call to boss arrives and is forwarded to secretary. Secretary answers call and presses the boss's DSS/BLF key. The call is transferred unsupervised to the boss, overriding CFA. For a supervised transfer, the secretary presses TRANS/CONF, then the boss's DSS/BLF, also overriding CFA.
Scenario #3	Multiple secretaries have DSS/BLF appearance of the boss's prime DN. (Boss is CFA to Secretary #1. All DSS/BLF keys are flashings.) All sets are idle. Secretary #2 presses the DSS/BLF key to call the boss, overriding CFA.
Scenario #4	Boss is is CFA to Secretary Secretary #1. Incoming call to boss arrives. Secretary #2 answers the call using a multicall appearance of secretary 1 (or CFA from Sec #1). Secretary #2 presses the boss's DSS/BLF key for unsupervised transfer—or TRANS/CONF then DSS/BLF for supervised transfer—to the boss, overriding CFA.

If the held party and the monitored set are interconnect restricted, automatic release is not attempted. If the set hosting the busy lamp has Brokers Call enabled, both parties are released.

Keys programmed for Secretarial Transfer otherwise operate as regular DSS keys.
