The Coral switching system is capable of switching digital data information as well as
voice signals. Coral system data communications devices are available for packet
switched data for low volume applications. The packet data communications are
provided using the APA (Application Processor Adapter), PEX+APA or APDL
(Applications Processor Data Link). The data communication devices provide a serial
interface wired as Data Communications Equipment (DCE). That is, they transmit data
is data to the APA/APDL, and receive data 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 a:
„
DB-25S connector on the rear panel of the APDL and DKT2000 with an APA
„
RJ-45 jack connector on the rear panel of the FlexSet 80, GKT, FlexSet APDL,
FlexSet APA or FlexSet 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:
„
CN#7244-8001195 for DKT2000 with APA or APDL
„
CN#7244-6914055 for FlexSet 80, GKT, FlexSet APDL, FlexSet APA or
FlexSet PEX+APA.
Tables below lists the pin designations for the RS-232 interface module of the various
Coral terminals.
