The Coral IPx Office switching system is capable of switching digital data information
as well as voice signals.
Coral IPx Office system data communication devices are available for packet
switched data for low volume applications. The packet data communication devices
are provided using the APA (Application Processor Adapter) or APDL (Applications
Processor Data Link). The data communication devices provide a serial interface
wired as Data Communication Equipment (DCE). That is, transmit data that is sent to
the APA/APDL, and receive data that is received from the device.
The APA provides a proprietary data link to an external applications processor. The
link uses an asynchronous RS-232E (V.24) serial data interface, operating at a data
rate of up to 19.2Kbps. The interface appears at the PC RJ-45 jack connector on the
bottom panel of the FlexSet 280S/281S/APDL with APA or PEX+APA.
Through the link, a proprietary signaling protocol allows the Coral system master
processor to send call status messages to the applications processor, and the
applications processor to send call control instructions to the APA/APDL. Application
processors available for the Coral system include the Computerized Attendant
Position (CAP), the ACD group supervisor and management position, Coral
CallMaster (CCM), Coral World Wide Office (WWO), TAPIdriver, GKT PC-Utility,
or any other application that complies with proprietary API products.
Use the following RS-232 cables:
