The DIP switch located on the right side of the CLA can be set to the following modes:
„
All the switches “Right” provides the mode for the normal working condition of
the CLA card.
„
Switches 1 through 3 “Left”, provides the debug mode. This mode is used during
software installation or for the use of technicians for software debugging.

CLA Functional Block Diagram
The functional block diagram is shown in
Figure 8-12 and Figure 8-13
.
The Ethernet Network Interface (LAN Communication Controller) is an adapter for
interconnecting the system with the Ethernet LAN external computer network. The
CoreModule 32-bit CPU compatible incorporates the elements of a PC compatible
computer and provides the processing power needed to control the CoraLINK adapter.
The CLA base card contains a PC104 BUS to interconnect the mini modules. The PC104
BUS is electrically identical to the ISA BUS.
The communication in this configuration is controlled by an intelligent CPU controller.
The communications software and part of the application software is run on the card
by the local CPU and is not loaded to the exchange call processor (MCP-IPx).
The base card contains a 256 Kbyte static RAM memory, shared between the CLA and
the MCP-IPx. The shared memory is accessed from the CLA card via the PC104 BUS
and via the J-bus from the MCP-IPx.
In the CLA 486 card, the 2MB flash memory EPROM on the base card contains the
card's software, which is burnt into memory during the regular software installation
procedure. The flash stores code for the card's program. The flash EPROM is connected
to the PC104 BUS.
In the CLA 686 card, the CFD (Compact Flash Disk) memory on the CFCLA mini
module contains the CLA card's software and programming code, which is factory
loaded. The CFD is connected to the PC104 BUS via the IDE BUS.
The CLA card also contains an NMI/watchdog circuit, providing a reset signal to the
CoreModule if it detects a failure in the software cycle.
