Telephone Terminology
When making or receiving calls on your DP5000-series telephone you may
experience one or more of the following call features depending on how your
telephone is configured.
•Line – is synonymous with trunk which is the line that connects you to the PSTN
(Public Switched Telephone Network). Line can be:
• a button on your telephone set designated for outgoing calls
• your DN button followed by dialing 9.
•Automatic Line Selection (ALS) – ALS is engaged on outgoing calls. Lift the
handset or press Spkr to hear dial tone, the steady green Line LED indicates ALS
in enabled. The second line of the LCD will display the method of dialing
available, followed by the digits dialed.
•Ringing Line Preference – Answer any incoming call by lifting the handset or
pressing Spkr. There is no need to press the ringing line button to answer the call
when ringing line preference is enabled.
•Tone First Signaling – Internal incoming calls only: telephone rings in standard
ring tone, lift handset or press Spkr to answer call.
•Voice First Signaling – Internal incoming calls only: a long tone is heard,
followed by the caller's voice, this will automatically engage the Spkr to allow for
hands free communications. Lift the handset if desired (for privacy). When Voice
First Signaling is enabled the telephone does not ring on internal incoming calls.
•Hot Dialing – Dial a telephone number from the dialpad, the telephone
automatically selects a line, shown with a green LED, and turns on the Spkr and
Mic LED's. When Hot Dialing is not turned on the handset should be lifted or Sprk
should be pressed in order to make a call.
