Linked-Pair Stations
Two stations can be linked together for use by a single user. By linking a digital phone with
another station, the user can use them alternatively.
CONDITIONS
• The system will support 13 linked station pairs.
• A station can be only linked with one other station.
• For purposes of assigning features and the intercom station number, one station in a
Linked-Pair is designated as a "Master" station, the other is the "Slave" station.
• The number used for stations in a Linked-Pair is the station number of the "Master" as
assigned in ADMIN PROGRAMMING.
• The attributes of the second station (Slave) follow the attribute settings of the Master
station (for example, settings for Day/Night COS, CO Warning Tone, CO Auto Hold, CO
Call Drop, and Alarm).
• If both stations in a Linked-Pair are idle both linked stations ring when a CO call is
received. However, if only one station in a Linked-Pair is busy when a CO call is received,
the caller will hear a busy tone.
• Any time one of the stations in a Linked-Pair receives calls (including intercom, CO,
DISA/DID, recall ring, or transfer), both stations ring.
• If one station in linked pair is in DND, call forward, or a pre-selected message display
state, the other station in the pair automatically assumes the same state. Conversely, it is
also true that if such a mode/state is cancelled/removed at one station in a linked pair, the
cancellation/removal is automatically applied to other station in the pair.
• If one station in linked pair is busy:
- "IN USE AT LINK STA" is displayed on the other station in the pair.
- the other station in the pair does not ring for incoming calls.
• Linked-Pairs are automatically set to Tone mode regardless of the current intercom
Answer mode setting of either station in the pair.
• One station in a Linked-Pair can call the other station by dialing the intercom number
(which is the same for both stations when linked).
• Both CO and intercom calls can be transferred between Linked-Pairs.
• The following cannot be included in a Linked-Pair.
- Doorboxes, DSS/BLFs, or ISDN phones
- Attendant stations
- Port blocked station
