Initialization
and
Administration
System (INADS)
A computer-aided maintenance system that offers AUDIX maintenance services at a
centralized location. Major and minor alarms are sent over the AUDIX ALARM
(H02) link using existing switch alarm-reporting facilities.
Initialization
History
Function 3 on the Control Mode Menu that displays the last hardware initialization
message.
Initialization
Options
A series of initialization choices available by manually selecting a nonstandard
initialization. The options include extended RAM tests, standard or nonstandard boot,
and stop points.
Initialization
Stop Points
An initialization option available through manual selection of initialization options,
allowing the initialization to be halted at some point, then resumed, for diagnostic
purposes.
Initializing a
Disk
Erasing a disk directory, then reading its volume label (name) from the
maintenance : dbp : equip form. Old disk contents are no longer
accessible.
Integrated
AUDIX
An AUDIX with a data link. Compatible switch software is required.
Integrated
Message
Notification
(IMN)
A feature that allows several message services to alert users of new messages through
a common service using descriptive announcements and the message-waiting lamp.
Also called Unified Messaging.
Integrated
Services Digital
Network (ISDN)
A protocol being developed in response to a recommendation from an international
standards body. It defines how equipment from different manufacturers should
communicate with one another in end-to-end digital connections using standard
interfaces.
Integrated
Services Line
Unit — T
Interface
(ISLU-T)
A 4-wire (2-pair) connection from CPE devices directly to the ISDN switch. This
connection may be used instead of installing an NT1 to convert 4-wire signals to the
2-wire U interface.
Intelligent
Peripheral
Controller (IPC)
AUDIX-L circuit pack (TN507C) that works with the DIM (UN161B) to comprise the
DBP disk controller.
Intelligent Unit Any circuit pack or group of packs controlled by a single microprocessor or
microcontroller that coordinates maintenance activities for that unit.
Interface The device or software that forms the boundary between two devices or parts of a
system, allowing them to work together.
Isolating Data
Interface (IDI)
A synchronous, full duplex data device used for direct cable connections between an
AUDIX with an SCPI and the switch DCIU.
