Hardware Requirements
An 80-Mbyte or 200 Mbyte hard disk
drive is required if IS II includes either
IVP AA or AVP.
Specify the number of rings before a call transferred by the AVP is sent to the
backup position (system operator).
When the AVP Automated Attendant is used only for Night Service:
If the lines/trunks set for answering by the Automated Attendant appear at
other stations, set the "no ring" option for the other stations.
Assign the dummy station to a Night Service group for each system
operator position.
Assign the dummy station to a coverage group, and assign the VMI
calling group to cover that coverage group.
Specify the VMI ports that provide Automated Attendant to be Automated
Attendant ports.
Specify the business schedule for AVP.
IS II uses an AT&T Master Controller based on an 6386/SX WGS Processor

optional tape drive (required for systems with a 200-Mbyte hard disk for
saving UNIX files, application program files, administrative files, and voice
system files during backup)
A 355 AF adapter for connecting the Master Controller to the serial port on
the control unit if they are within 50 feet of each other and are on the same
AC branch circuit
ADUs for connecting the Master Controller to the serial port on the control
unit, if they are not within 50 feet of each other and/or are not on the same
AC branch circuit
Any additional hardware required by the individual applications included in
IS II, including the cables and adapters for connecting the applications to the
system (see the instruction booklet that comes with each application)
