Data Communication Ports
RS-232E
The Coral IPx 500 switching system is capable of switching digital data information as
well as voice signals.
Coral IPx 500 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 is data that is sent to
the APA/APDL, and receive data is 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 a DB-25S connector on the rear panel of the
APDL and DKT2000 with APA, or at a RJ-45 jack connector on the rear panel of the
GKT and FlexSet 280S/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:
„
Catalog no. 7244-8001195 for DKT2000 with APA or APDL.
„
Catalog no. 7244-6914055 for FlexSet 280S/APDL with APA or PEX+APA with
APA or FlexSet 80 (GKT).
Table 5-5
lists the pin designations for the RS-232 interface module of the APA/APDL.
