Types Of Adaptive Integration; Enhanced Dtmf In-Band Integration - Toshiba VP 300 Installation Instructions Manual

TYPES OF ADAPTIVE INTEGRATION

There are several types of data exchange that the VP 300 can process to perform integration:
•
Enhanced DTMF In-band signaling
•
RS-232C data link, including CO Centrex
•
Proprietary display set emulation
I Enhanced DTMF In-band Integration
While Standard DTMF Integration processes DTMF mailbox digits prefixed to a call, Enhanced
DTMF In-band integration enlarges the scope of the data exchange to fully detailed call records.
Enhanced DTMF In-band integrations require a unique call type identifier for each type of call. These
identifiers determine the VP 300 responses. For greater system efficiency, Enhanced DTMF In-band
integration uses ports in AX mode, which does not require system ports to be split into groups.
Figure 8-1 illustrates the interaction between the VP 300 and the PBX in an Enhanced DTMF In-band
Integration environment. An explanation of Figure 8-1 follows the diagram.

1. The VP 300 can receive direct calls to the pilot number.
2. The VP 300 can also receive forwarded calls from busy or unanswered extensions.
With Enhanced DTMF In-band Integration, the PBX sends a call record to the VP 300 containing
additional information about the call. The call record is sent over the ports in the form of DTMF
tones. MWI commands are sent by the VP 300 over the ports as well. All ports can be placed in a
single hunt group because the information in the call record determines how the call will be answered.
