3.17 CENTRALIZED ACTIVITY LOGGER (CAL)
CONFIGURATION
The Centralized Activity Logger (CAL) computer uses the call activity
information provided by the Centralized Activity Module (CAM) to
generate usage and billing information. The CAL is connected to the
CAM Controller Board (the CAM consists of this single Controller
Board) by a synchronous high-speed HDLC serial control data link.
This CAM-to-CAL HDLC link can be set by DIP switches on the CAM
Controller Board for either 60k or 360k baud operation. Refer to
CEC/IMC Digital Audio Switch Installation, Set-Up, and
Troubleshooting (LBI-38939) for specific information on DIP switch
settings and cable connections.
3.18 AUXILIARY I/O CONFIGURATION
Every CEC/IMC Controller Board has eight input (I) lines and eight
output (O) lines that can be used for auxiliary I/O interfacing to two-
state external devices.
The V5.0 CEC/IMC and CEC/IMC Manager for Windows NT fully
support the definition and configuration of up to 255 auxiliary I/O lines
for console use. Configuration of single control input and output, and
interlocking group control is supported. However, the first release of
the console does not support interlocking group control, and will not
obtain event labels and message information from the CEC/IMC
Manager. Refer to the C3 Maestro for Windows NT Engineering
Release Notes (1551-CXC 112 887 Uen) for the console limitations in
its first release. Subsequent releases of the console to support this
feature should require no further changes in the CEC/IMC.
Since the number of I/O controls has increased from 30 to 255, the key
and message event information is not stored in MOM Controller
NOVRAM. Configuration I/O information read from the MOM
Controller by the CEC/IMC Manager doesn't include this information;
however, the current state of the I/O link will be available.
Each I/O line can be individually defined at the CEC/IMC Manager for
console I/O use. For example, an output can be used to turn on a siren
when a console operator presses a key and an input could be used for
alarm monitoring. As mentioned previously, up to 255 different I/O
events can be configured at the CEC/IMC Manager. Event
configuration is done from the Auxiliary I/O Event Configuration
dialog box, Figure 40. From the CEC/IMC Manager menu bar select
