SCSI-to-AUDIX
Disk Interface
(SADI)
The SADI (TN475B) is the AUDIX disk controller. It uses the Small Computer
Systems Interface (SCSI) protocol to communicate with the AUDIX disk drives. The
SADI’s LEDs show which drives are active. The 50-pin drive data cable is called the
SCSI cable.
Simplified
Message Service
Interface
(SMSI)
Type of data link connection to an integrated 1A ESS Switch or 5ESS Switch in
AUDIX R1V4 software.
Service Not
Started
A message displayed at the end of unsuccessful initialization which indicates software
problems, such as a missing or corrupt (bad) filesystem. Normally the system can still
display forms, but cannot provide service (answer calls). You may log in after this
message.
Shutdown A procedure required to disable system operation and protect customer data stored on
disk before a power down. Select the type of shutdown based on the tasks you need
to perform and their urgency, using either the shutdown form or MI toggle switch.
Split A group (or queue) of analog ports on the switch. See also Call-Distribution Group.
Standalone An R1V3 AUDIX feature that allows AUDIX to connect to any switch without using
a data link. This allows AUDIX to work with a switch built by a different vendor or
one that runs an incompatible load of software.
Standard
Initialization
(Standard Boot)
The normal automatic (default) initialization of the AUDIX system, where firmware
first scans for the program ‘‘boot_f’’ on disk 0/0. If not found, the firmware looks for
another boot filesystem to load until all possible combinations have been examined.
Start Service A message displayed at the end of a successful initialization, indicating that system
software is active and display forms are available.
Start-up See Restart.
Status Line The top line of an administration or maintenance form displayed on a terminal,
showing the active system alarms (if any), logins (up to two), and threshold (disk
space) violations.
Subscriber A person to whom the AUDIX administrator assigns the ability to access the Voice
Mailbox feature. Subscribers may also be assigned the optional Call Answer feature
on the subscriber : local or cos forms or given LWC permission through
the switch.
Subsystem A major functioning element of AUDIX software and hardware. Subsystems include
the Feature Processor (FP), Data Base Processor (DBP), and (on AUDIX-L only) the
Voice Session Processor (VSP). VSP devices on AUDIX are run by the FP.
Switch An analog, digital, or electronic system where data and voice transmissions are not
confined to fixed communications paths, but are routed among available ports or
channels.
Switch
Communications
Adapter (SCA)
Custom device used for making AUDIX connections to a 5ESS Switch.
