SYSTEM CHECKOUT 
Initial Condition 
- 
The system operating features are set to a set of default conditions 
at initial power 
up. These conditions provide a basic operating 
system with a known set of parameters, 
and the 
system should be 
initially checked out with the default conditions in place. At 
anytime while the system is operating, 
default conditions can be reset 
from station port 10 or 11 per the instructions provided in Chapter 3. 
Check 
Out 
Check the KSU and telephone installation for proper operation by 
performing the following resistance and voltage measurements. 
Resistance Check 
Make the following resistance measurements at the station connector 
blocks under the following conditions. 
0 KSU AC power cord disconnected from electrical Outlet. 
0 Power interconnection cable connected between KSU and power supply. 
e KSU connected to station connector 
blocks. 
0 Stations wired, and wiring punched down on blocks. 
l 
Bridging clips removed from blocks to isolate stations from KSU. 
1. Measure the resistance of each installed station and wiring from 
the station side of the connector 
blocks. Resistance values will 
vary with 
cable length and station type but should be within the 
following limits.

General Check 
1. Check the red light emitting diode (LED) 
system status indicator. 
Be sure that it is on steady. 
If it is off or flashing, 
disconnect and reconnect the AC power plug. If the indicator is 
still not on steady, refer to the Failure Analysis Flow Chart 
found in Chapter 4. 
2. 
Refer to the station Users 
Guide for operating information. 
Perform a general operational test of the 
system by exercising the 
system features from station port 10 or 11. 
Operational 
parameters are per the 
system default conditions as detailed in 
Chapter 3 until Class Of Service (COS) programming is performed. 
3. Once the basic system is verified as operational, perform the COS 
programming.

CHAPTER3 
SYSTEMPROGRAMMING 
GENERAL INFORMATION 
l Class Of Service (COS) programming consists of the following major 
categories: 
.Station COS. General System COS, Toll Table Entry, Line COS, and 
l All COS programming commands must originate at a 22 Line/Feature 
Keyset installed at station port 10 or 11 and a companion DSS/BLF 
Console installed at adjunct port 10 or 11 respectively. 
No COS 
programming commands will be accepted from any other stations 
connected to the system. 
NOTE 
A Model 1432 KSU Rev. 
A through M can only be programmed 
from a keyset and console installed at station port 10 and 
adjunct port 10. 
Programming of these KSU revisions from 
station port 11 and adjunct port 11 is not permitted. 
l Programming overlays are included with each system for use in 
identifing the keys required for COS programming. 
One overlay fits 
over the keys of the station installed at station port 10 or 11 and 
designates the A-field and B-field keys. 
The other overlay fits 
over the keys of the console installed at adjunct port 10 or 11 and 
designates the C-field keys. 
l System and line COS programming do not require that a sequential 
process be followed once the base level program entry mode has been 
established except where noted herein. 
Station COS programming does 
follow a sequential process. 
l Prior to taking any programming action, determine the system, line 
and station COS conditions and all toll restriction requirements. 
Record this data on the programming reference tables included within 
the programming procedures. 
8 A set of COS values can be recorded on cassette tape from a 
programmed system and later re-loaded into the same system or into 
another system. 
This method of programming can be employed in lieu 
of using the step-by-step programming sequence. 
l A complete or a partial printed record of the COS program values can 
be obtained with a serial data printer connected to the SMDR output 
lines of the KSU. 
Complete details concerning this procedure are 
included at the end of this, chapter. 
l On a KSU Rev. 
A through M, programming steps must be performed with 
less than 17 seconds between keystrokes; otherwise, a timeout will 
occur. 
If a timeout occurs, 
the programming mode must be 
re-entered. 
The timeout period for a KSU Rev. N and above has been 
. 
extended to 5 minutes.

SPECIAL PROGRAMMING RE~UIRk9lENTS 
SINGfX-LIidE KEYSiE!lS 
Several programming steps under COS programming must be observed for 
proper operation of a Single-Line Keyset. 
. 
@ When the system is strapped for key system configuration, the 
Single-Line tieyset is an intercom only station. It can 
be 
configured for private line only by programming the applicable 
station port for the prime line 
automatic feature. When the port is 
programmed with the prime line 
automatic feature, the Single-Line 
Keyset cannot 
be programmed with station speed dial numbers. 
0 hihen the system is strapped for the multifunction (hybrid) system - 
configuration, 
to originate outside calls with a Single-Line Keyset, 
one or more lines must be programmed into a line group. 
8 In order to receive outside calls on a Single-Line Keyset, the call 
must be answered by an attendant using a multiline station and 
transferred to the single-line station. 
Otherwise, the Single-Line 
Keyset station port 
must be programmed to have the ringing line 
preference feature with ringing enabled on all desired lines. 
Alternately it can 
be programmed to have the prime line automatic 
feature with ringing enabled at the prime line. 
REUSED d LINE BLF 
KEYSE’l 
Even though an 8 Line ELF Keyset is physically connected to only one 
station port, it appears to the system as two data-paired stations. 
Special programming is required to enable proper operation of a reused 
tl Line BLF Keyset. 
0 The station port to which it is connected 
must be programmed for a 3 
and 8 Line Keyset 
l The paired station port must be programmed for an 8 Line BLF Keyset 
although it can not be connected to any equipment. 
@ When the 8 Line BLF Keyset is connected to station port 11, 12, or 
13, the respective adjunct port serves as the paired port. 
0 When connected to station ports 14 through 41, the paired port is as 
charted in Chapter 2, Installation, or Chapter 5, Maintenance. 
After COS programming of the station port is complete, the DSS/BLF 
keys of the 8 Line tiLF Keyset must be programmed, from that station. 
Program them to contain the intercom dialing sequence for each station 
in the 
system for which visual indication is desired. 
It should be noted that certain features, 
such as call-back messaging, 
are not available with tne 8 Line BLF Keyset.

							IMI 66-036 Programming 
BASE LEVEL PROGRAM ENTRY MODE 
I 
The first step in any COS programming sequence is to enter the base 
level programming mode from station port 10 or 11 (port 10 only for 
KSU rev. A through M). 
Once in this mode, COS can be set as desired. 
To enter base level: 
1. Press the 
ITCM 
key. The dial tone will sound. 
2. Press the following keys in sequence: * 7 4 6 
Note that the dial tone stops and a tone burst sounds to indicate 
that the base level programming mode is entered. 
3. Press the * 
key. The dial tone will return as a confirmation 
that the base level mode is active. 
4. Proceed from this point to program the system, line, or station 
COS and the toll restriction tables. 
CLASS OF SERVICE DEFAULT 
The system can be defaulted to a standard class of service per the 
following procedure. 
The default conditions are listed at the 
beginning of each COS programming procedure and shaded on the 
programming reference charts.

PROGAMMING OVERLAYS 
Several different telephone and console overlays are packed with the 
system. The overlay to be used is dependent upon the particular models 
of equipment connected to the programming station port (10 or 11) and. 
the respective adjunct port (10 or 11). 
illustrated in Figure 3-1. The programming overlays are 
Full-scale copies of the overlays are also 
included at the end of this chapter. 
The full-scale copies can be 
removed and prepared for use if needed.
