CHECKOUT
Check the KSU and telephone installation for proper
operation by performing the following actions.
Resistance 
Check
Make the following resistance measurements at the Sta-
tion connector blocks under the following conditions.l
AC power cord disconnected from electrical outlet.l
KSU connected to station connector blocks.l
Stationswired, and wiring punched downon blocks.l
Bridging clips removed from blocks to isolate sta-
tions from common equipment.
1.Measure the resistance of each installed sta-
tion and wiring from the station side of the con-
nector blocks. Resistance values will vary with
cable length and station type but should be
within the following limits. Readings which are
outside of these limits indicate a possible wiring
or station problem.

Check the red light emitting diode (LED) sys-
tem status indicator.
Be sure that it is on steady.If it is off or flash-
ing, disconnect and reconnect the AC power
plug.If the indicator is still not on steady, referto the Failure Analysis Flow Chart found in
Chapter 4.
Refer to the station User’s Guide for operating
information.
Perform a general operational test of the sys-
tem by exercising the systemfeaturesfrom sta-
tion port 10 or 11. Operational parameters are
per the system default conditions as detailed inChapter 3 until COS programming is per-
formed.
Once the basic system is verified as operation-
al, perform the COS programming.

CHAPTER 3
SYSTEM PROGRAMMING
GENERAL INFORMATION
Class Of Service (COS) programming consists of
setting the Class Of Service (COS) operating con-
ditions. COS programming is divided into the fol-
lowing three major categories: System COS, tine
COS, and Station COS.
All COS programming commands must originate at
station 10. No COS programming commands can
be accepted from any other station connected to the
system. COS programming causes station 10 todefault to a square condition (line select key 1
selects line 1, key 2 selects line 2, etc.). It is recom-
mended that station 10 always remain in a square
conditionto avoid possible programming confusion.
COS programming does not require that a sequen-tial process be followed once the base level
program entry mode has been established except
where noted herein.
The system defaults to preset characteristics when
it is initially powered up or whenever programmed
to do so.If the default characteristics, or any otherpreviously set characteristics, are satisfactory,
those portions of the programming sequence may
be omitted.
Prior to taking any programming action, record the
system, line and station COS conditions on Table
3-1,3-2, and 3-3 (included at the end of this chap-
ter). Also, record all toll 
restdction requirements on
Table 3-4.THE PROGRAMMING STEPS MUST BE PER-
FORMED WITH LESS THAN 17 SECONDS OF
DELAY TIME BETWEEN KEYSTROKE OPERA-
TIONS. A delay of longer that 17 seconds causes
the KSU programming mode to time out.
Flgure 3-3 found at the end of this chapter provides
a quick-reference flow diagram of the class of ser-
vice programming requirements.
Programming is the same for both the model 0616X
and 0816X key systems. The only difference be-tween these two models is the number of lines
which each serves (six or eight).
BASE LEVEL PROGRAM ENTRY MODE
The first step in a COS programming sequence is to
enter the base level programming mode. Once in
this mode, COS can be set as desired.
1.Press ITCM. The dial tone will sound.2. Press the following keys in sequence: 
8 7 4 6.
The dial tone stops and a tone burst sounds to in-
:
3.
c&ate that the base level programming mode is
entered.
Press 
*. The dial tone will return as a confirma-
tion that the base level mode is active.
CLASS OF SERVICE DEFAULT
The system can be defaulted to a standard class of
service per the following procedure.1. Press 
ITCM.
2.Press the following keys: * 7 4 6 * # 0 *3. Press MONITOR.

PROCEDURE
NOTE: Before peffotming this procedure, turnto the Station COS Programming Reference
Chart (Table 3-3), located at the end of this chap-
ter, and record ail station COS requirements on
it.
1.Enter the base programming mode:l
Press ITCM +# 7 4 6 +#. Dial tone will
sound.
2.Press a two-key sequence on keypad to choose
station port for programming (i. 
e.,to choose sta-

selection. Improper selection results in dial tone.
NOTE: Station port selection defaults the foi-
lowing features: 
DSS/BLFport enable, ,PA port
enable, prime line selection, and ringing line
preference enable. Pius, toil restriction table
assignments are disabled.
3.Configure port as DSS/BLF console port (if con-
sole port is required)..
Press RECALL. Tone burst sounds to
confirm selection.l
Skip this step if DSS/BLF console is not
installed at station port currently being
programmed.l
If enabled, do not proceed beyond this
step unless port is also to be
programmed as PA port.
4.Configure port as PA port (if PA port is desired).
*Press 9. Tone burst confirms selection.
:
aSkip this step if PA port is not desired.l
Do not proceed beyond this step if PA
port selection 
is made.5. Choose prime line or prime 
fntercom. Tone
burst confirms selection.l
Press tine select key for line desired.
-or-* Press 
ITCM.NOTE: if more than one iine selection key is
pressed, the last one pressed selects the 
ac-
cep ted prime line.
6. Enable ringing line preference.l Press 1.
7. Press memory keys to assign toll restriction
tables 
to station.l
At this point, there are no toll restriction
tables assigned.l
Tone burst confirms each selection.
Skip to step 16 after programming the toll restric-
tion table assignments unless other station COS
programming 
must be performed.l
Durfng initial programming of a station, it
is recommended that programming steps
8-14 be performed in the order that they
are presented below. In steps 8-14, the
defautt condition is automatically set
whenever the program selection key is
pressed. This default value is overridden
by the subsequent programming action.l
During subsequent reprogramming of a
station, any step, controlling a feature
that does not need to be reprogrammed,
can be skipped over thus leaving the cur-
rent COS condition intact. 
It is not neces-
sary to return to the base programming
mode to shift from one programming step
to another except when performing step
15. Program step 15, which sets the line
appearance to key assignment, must be
followed by a return to base level
programming (press 
*).
8. Program direct ringing assignments.NOTE: A 
line may be programmed for direct
ringing or delayed ringing but not for both ring-
