floppy disk drive
A storage device, typically referred to as the A or B
drive, capable of reading and writing information to dis-
kettes (3.5-inch or 5.25-inch). Amanda and its associat-
ed utilities are distributed on 3.5-inch 1.44 MB diskettes
only. Therefore, the PC designated for Amanda must
have at least one 3.5-inch 1.44 MB floppy disk drive (A
or B).
general protection fault
A fault that can cause a program to crash or produce an
incorrect result. The error might be due to a logical error
in the software, faulty hardware, or corruption of mem-
ory location caused by other programs.
glare
The collisions between incoming calls and notifications.
For example, a port might try to execute a notification
record and accept an incoming call simultaneously.
hard drive/hard disk
A long-term storage device, typically referred to as the
C drive, on which Amanda is installed. The Amanda
Company recommends using IDE hard drives with a
12ms access time or faster to insure optimal processing
of calls. Consider large capacity hard disks if a high vol-
ume of outgoing and incoming messages is expected. A
540 MB hard disk is estimated to provide 33 hours of
messages.
hookflash
A momentary on-hook condition which lasts anywhere
from 0.25 seconds to 0.85 seconds (usually set to 0.55
seconds.) which is normally required to put a caller on
hold before Amanda can transfer to an extension. This is
also used when Amanda determines a Ring No Answer
or Busy extension. A second hookflash (or hook-flash)
makes Amanda able to get the caller back and play the
current greeting or Busy message for that user.
