Feature Description
50003510 Revision A 173
Line Privacy
This feature ensures that, if desired, conversations on Key, Direct Trunk Select, CO Line, and
Private Trunk Lines are private. When such a line is in use at one set, other appearances of
the line cannot join the conversation.
Line Selection
SUPERSET telephones are equipped to have many line appearances programmed on them.
When the user starts dialing, the system selects a line (if programmed to do this). When the
set is ringing and the user goes off hook, the system selects the line to answer. The user can
also select a specific line to make or answer a call.
Line Types and Appearances for SUPERSET Telephones
SUPERSET telephones are equipped with keys that can be used as Line Select Keys. These
lines can provide additional calling capability, direct access to calls appearing at other sets,
and direct access to trunks. There are seven types of lines:
• Prime Line
• Key Line
• Multicall Line
• Direct Trunk Select Line
• Private Line
• Personal Outgoing Line
• BLF/DSS Line.
Some line types can appear on only one SUPERSET telephone. Other line types can appear
on more than one telephone. Because the same line may appear on up to a maximum of 32
other sets, the telephone and the lines are not always busy at the same time. One or more
lines may be in use but the telephone is idle and available for a call.
Prime Line: The SX-200 EL and SX-200 ML system identifies each SUPERSET telephone by
an extension number known as the Prime Line. The Prime Line is always a Both-Way and
Immediate-Ring Line. A Prime Line can be changed to operate as a Multicall or Key Line by
giving the line an appearance at another set. If an appearance of a Prime Line is programmed
at other sets as a Multicall Line, the Prime Line operates as a Multicall Line. If an appearance
of a Prime Line is programmed at other sets as a Key Line, the Prime Line operates as a Key
Line.
Key Line: A Key Line is an appearance of one extension number on two or more telephones.
This extension number can be for another SUPERSET telephone or an industry-standard
telephone. If the line is in use at one set, the other appearances of the line are busy and
unavailable.
- There can be only one appearance of any one Key Line on a SUPERSET telephone.
- Call Direction and Ring Variants can be programmed independently for each appearance.
