FUNCTIONAL DESCRIPTION
Memory
Administration and Feature Code Modules, which includes Station Call Processing, are
software tasks associated with memory.
Each task controls the storage and movement of
data and messages between elements in the system.
● Administration
Provides for administration of station and system features. This software also
supports maintenance procedures related to error checking and diagnosing trouble.
● Feature Code Modules
Includes the software that receives and sends data to/from the Operating System, as
well as control of all voice and data features supported by the system. Station Call
Processing includes the processing of messages and data associated with voice
terminal on-hook/off-hook indications, associated port identifications, button and LED
operations, etc.
The SMDR software generates SMDR records associated with a
particular call. The records are then sent to the System RAM for storage and then to
the SMDR output channel.
Call Processing
The following circuits support software tasks.
● System RAM provides for the storage of the following:
— Variables for the various software tasks
— System translations
— Error Records
— Feature Code Data
— Stack.
● Error Logger
Prioritizes and stores system errors; lights the Alarm LED on the Attendant Console
when a serious error is detected. The errors are stored in three error records in
System RAM:
— Permanent System Alarms
— Transient System Errors
— Most Recent System Errors.
