Ericsson LBI-39224 Centralized Activity Logger CAL Configuration, Auxiliary I/O Configuration

LBI-39224

3.17CENTRALIZED 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
