STANDARD DTMF INTEGRATION VS. ADAPTIVE
INTEGRATION
Standard DTMF Integration and Adaptive Integration (AI) depend on the capabilities of a PBX and
standard or optional features of the Octelt 200/300.
Standard DTMF Integration uses Octel 200/300 standard features only. Adaptive Integration may also
require additional hardware, consisting of additional cabling.
Message Waiting Indication. In a standard Octel 200/300, when the first new message is left in a
mailbox, ringing message waiting notification (MWN) is provided. The Octel 200/300 calls the extension
of the mailbox with a new message and, if the call is answered, plays a prompt indicating that there are
messages in the mailbox. Message waiting indication (MWI) is an alternate method of notification.
Depending on PBX functionality, any of the following may occur:
The telephone message lamp may be lit,
-
Stutter dial tone may be provided when the telephone receiver is off hook and a message is waiting,
-
or
With Adaptive Integration, a display phone may indicate that a message is waiting.
-
Only one method, either message waiting notification or message waiting indication, is used for a
mailbox. Both methods may not be used at the same time for the same mailbox.
Normally, MWN and MWI are turned OFF when the mailbox is logged on to, whether messages are
listened to or not.
MWI operation can be varied in the following ways:
To activate the MWI for each new message (System Parameter 83 — LAMP MW: LIGHT LAMP
-
FOR EACH NEW MESSAGE).
To call the extension before activating MWI (System Parameter 84 — LAMP MW: CALL
-
EXTENSION BEFORE LIGHTING LAMP).
To turn OFF MWI only when a mailbox contains no messages (System Parameter 166 — LAMP
-
MW: TURN OFF ONLY IF NO NEW MESSAGES).
These configurable settings apply to all mailbox holders system-wide and are generally selected for a
better match with the PBX functions.
Called Party Identification. A standard Octel 200/300 normally supervises calls. After collecting
digits and outpulsing them, the Octel 200/300 monitors the line to detect ringing, answer, busy, or all
calls forwarded. By staying on the line until the call is released, the Octel 200/300 maintains knowledge
of the number that was called and can direct messages correctly.
Some PBXs can forward information about a call to the Octel 200/300. Depending on the method a
particular PBX uses to send the information, Standard DTMF Integration or Adaptive Integration can
process the information to tailor system operation to the type of call received.
