Maintenance
Faults
in the system
are repaired
by replac-
ing any faulty
component
(printed
circuit
board,
subassembly,
telephone,
etc.) and returning
it to
the
manufacturer
for repair.
In
addition,
remote
administration/
maintena-rice
allows
the system
to interface
via
an SDTU
(built-in
modem)
with
a remote
loca-
tion.
This reduces
the cost of routine
data
base
changes
by eiiminaring
the need of a technician
to be ?n-site
for each
software
change.
