InstallationSYSTEM CHECKOUT
Initial Condition
The system operating features are set to 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 common equipment 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.
.AC power cord disconnected from electrical outlet.
.Power interconnection cable connected between common equipment and
power supply.
. Common equipment connected to station connector blocks.
. Stations wired,and wiring punched down on blocks.
.Bridging clips removed from blocks to isolate stations from common
equipment.
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.

Variant readings can indicate a possible wiring, station, or common
equipment problem.
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.

CHAPTER 3
SYSTEM PROGRAHNING
GENERAL INFORMATION
Class Of Service (COS) programming consists of the following major
categories:
. General System COS
.Toll Table Entry
. Line COS
. Station COS
.COS programming is performed from the attendant station
.Executech II multiline telephone installed at station port 10 or
11 and a companion DSS/BLF Console or Adjunct Feature Module
installed at console port 10 or 11 respectively.No other type of
Executech 
keyset can be used for programming nor will any COS
programming commands be accepted from any other station port.
.COS programming can also be performed from any customer-provided
Video Display Terminal (VDT) which has an RS-232 compatible, serial
interface.VDT programming is completely menu driven and easy to
follow.
.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 and designates the A-field and B-field
keys.The other overlay fits over the keys of the console and
designates the C-field keys.
.System and Line COS programming do not require that a sequential .
process be followed except where noted herein.Station COS
programming follows a sequential process.
.Prior to taking any programming action,determine the desired system
parameters and all toll restriction requirements.Record this data
on the programming referencetables located at the end of the
chapter.
.Block programming can be performed after a class of service has been
programmed for a particular station.Block programming will program
a group of stationsto have the same class of service as the
programmed station.This feature eliminates the need to
individually program stationsrequiring the same class of service.
.A set of COS values can be recorded on cassette tape from a
programmed system..This data can later be re-loaded into the same
system or into another system of the same model number.This method
of programming can be employed inlieu of using the step-by-step
programming sequence.
3-l 
						

							IMI 66-060Programming
IMPORTANT NOTE: The COS values that are recorded from an an older
model K2264 revision A through H cannot be re-loaded into any model
K2264 with a later revision or manufacturing code.
Doing so, will
cause the newer model K2264 common equipment to enter a lock-out
condition which will prevent any further manual COS programming  of
it and which can only be cleared by disconnecting AC power from the
equipment for a period of at least 48 hours. Access to COS
programming via a VDT Terminal connected to the data port is usually
still possible  however.
Whenever down-loading COS data to  a  cassette tape, it is a good
practice to carefully record on the cassette tape label the model
number and manufacturing code of the common equipment cabinet.
SPECIAL PBOGBAIMIBG BEQlJIREHEgTS FOR SIBGLE-LIBE KEYSETS
Several COS programming details must be observed for proper operation
of a Single-line  
keyset.
Key System Configuration
The Single-line keyset can be programmed either for prime intercom or
for prime line automatic. Default is prime intercom.
Prime Intercom
When programmed for prime intercom, outside calls and outside line
access for call origination are extended to the Single-line  
keyset by
the attendant station or another multiline station through the use of
the call transfer feature. Outside lines can be programmed to  
ring,at
a Single-line  
keyset through the use of the ringing line preference
feature with ringing enabled for all desired lines.
Prime Line Automatic
When programmed for prime line automatic, and with an outside line
assigned to the port, the Single-line 
keyset, can originate outside
calls on the prime line. However,
intercom call origination is not
available (intercom calls  can be  answered). Because of the
unavailability of intercom call origination, those  system  features
requiring access through intercom dialing codes are unavailable.
Plus,no station speed dial numbers can be stored at that Single-line
keyset. 
						

							IMI 66-060
Programming
Hybrid Configuration
The Single-line 
keyset is a prime intercom station, however; access to
outside lines is made available through COS programming.
To receive outside calls on a Single-line 
keyset,
. The call must be answered at a multiline station and extended to
the Single-line 
keyset through the use of the call transfer
feature.
. Alternately,the Single-Line 
keyset station port can be programmed
to have the ringing line preference feature, and to have ringing
enabled on all desired lines.
. Or the port can be programmed to have the prime line automatic
feature and to have ringing enabled at the prime line.
To originate outside calls with a Single-line 
keyset,
. One or more lines must first be assigned to a line group and the
group assigned to the station by class of service programming.
With
a line group available,dialing the group access code over the
intercom line will access the outside line group for 
use*
BASE LEVEL PBOGBAH ENTRY HODE
The first step in any COS programming sequence is to enter the base
level programming mode from station port 10 or 
11.Once in this mode,
COS can be set as desired.
To enter base level:
1.Press theITCH 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.

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.

PBOGAHHING 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 connectedto the programming station port (10 or
11) and the respective console port (10 or 11).The programming
overlays are illustrated in Figure 3-l.Full-scale copies of the
overlays are also included at the end of this chapter.These full-
scale copies can be removed and prepared for use if needed.
