7. SYSTEM INDICATORS AND CONTROLS
7.00 Several system indicators and controls are
located on the various PCBs and assemblies. The
locations and functions are:
NFDU
l
Disk Drive LED-Will light to indicate when
the disk is being accessed.
l
PUSH Button-Used to eject the diskette
from the drive.
LCCU
MAJ LED-Lights when a MAJOR alarm
exists in the system.
MDR LED-Lights when the DTRsignalfrom
the SMDR device is not present. An MDR
alarm on the attendant console lights simul-
taneously if enabled in programming.
AUX LED-Lights when the DTR signal from
the MIS system is not present.
TTY switch-Slide switch used to select 300
or 1,200 bps speed for TTY port. This port is
used for either programming and mainte-
nance and/or the Lodging/Health Care Audit.
MDR switch-Slide switch used to select 300
or 1,200 bps speed for the SMDR port. This
port is used for SMDR and/or the Lodging/
Health Care Audit.
AUX switch-This switch is used with MIS
system. Must be set at 1200 bps.
NTWU
l
CLOCK LED-Flashes contjnuously when
the system is functioning as usual.
NPRU
l
FALT LED-Indicates software-detected
faults concerning MOH or Paging circuits.
. BSYLED1&2
#l lights when any page is in progress.
#2 indicates when MOH is in use (a call is on
hold or camp-on).
l
MOH volume control-Adjust, Music-on-hold
volume level.
l
LOAD switch-A momentary switch used in
an emergency condition to reload system
program and data from disk. All existing calls
will be dropped when this switch is pushed.
l
INT switch-A momentary switch used in
2-7

emergency conditions to reset system logic.
All existing calls will be dropped when this
switch is pushed.
PFT switch-A locking switch used to manu-
ally activate a transfer with the DPFT unit. A
transfer activated by this switch can only be
reset by this switch.
MDM LED-Not currently used.
PFT LED-LED is ON whenever a power fail
transfer condition has been manually initi-
ated.
NRCU FALT LEDs 1, 2, 3 & 4-Used to
indicate software-detected faults or a dis-
abled state caused by an input command
from the maintenance terminal (TPER Pro-
gram). Each LED indicates two of the four
circuits on each of the two NRCUs that can
mount on the NPRU.
FALT #l = Circuits 1 & 2, NRCU2 1
FALT #2 = Circuits 3 & 4, NRCU2 1
FALT #3 = Circuits 1 & 2, NRCU2 2
FALT #4 = Circuits 3 & 4, NRCU2 2
NCOU/NEMU/NLSU
l
FALT LEDs 1 & 2-Indicate software-de-
tected faults or a disabled state caused by an
input command from the maintenance termi-
nal (TPER Program) or while ports are pro-
grammed. Each LED indicates two of the
four circuits on the NCOU, NEMU or NLSU:
FALT #l = Circuits 1 & 2
FALT #2 = Circuits 3 & 4
. BSY LEDs 1 w 4-Indicate the busy/idle
status of each of the four circuits on the
NCOU, NEMU or NLSU. LED is ON when
circuit is busy.
NDTU
l
FALT LED-Indicates software-detected
faults or a disabled state caused by an input
command from the maintenance terminal
(TPER Program) or while ports are pro-
grammed. LED indicates fault occuring in
more than one channel.
l
BSY LED-Indicates the busy/idle status of
the 24 channels on the NDTU. LED is ON
when more than one channel is busy.
l
FALM LED-Indicates NDTU has not
achieved Synchronization.
