							Voltage CheckGeneral Check
Make the following voltage measurements at the
station connector blocks under the following conditions:
l Bridging clips installed
l AC power connected to the KSU
Measure the voltage across one voice line and one
data line and then across the other voice line and the
other data line for each even and odd station. The
measured voltage must be per the following chart.
Variant readings can indicate a possible wiring,
station, or KSU problem.
1.Check the red light emitting diode (LED) system
status indicator. Be sure that it is on steady. If if 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 User’s Guide for operating
infomration.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 
defauff conditions as detailed in
Chapter 3 until Class Of 
SeWice (COS)
programming is performed.
3. Once the 
basic system is verified
as operational, perform the COS
programming.

							CHAPTER 3
SYSTEM PROGRAMMINGGENERAL INFORMATION
Class Of Service (COS) programming consists of
the following major categories: General System
COS, Toll Table Entry, Line COS, and Station COS.
Class of service programming can be performed
from 
either station port 10 or station 11. In addition,
a 
32-button DSS/BLF console must be installed in
the adjunct port 10 or 11 respectively.
l When programmlng from station port 10,
employ an LCD Speakerphone and take note of
the following important condition: The LCD
~pdWpitul~b do& trot provide buttons 84
through B8. In performing the fo//owing
procedures, whenever a programming step calls
for buttons Bl through 
B8 to be pressed, first
press the 
BI burton to shift the A-field buttons.
When shifted, buttons A 
1 through A8 will
represent buttons B7 through B8. The BI butfon
performs a 
shift/no-shift toggle action each time it
is pressed.The associated indicator turns on
(shift) when A 
7 - A8 = Bl - B8 and off (no-shift)
whenA -A8=Al -A8.
It Is very Important to return the A-field
buttons to their normal, or no-shift, state
after the required Bl - 88 programmlng
action Is taken.
l When programming from station port 11,
employ a 22 Line/Feature keyset, and perform
the procedures as detailed in this chapter.
Programming overlays are included with each
system for use in identifing the buttons required for
COS programming. One overlay fits over the
buttons of the station installed at station 
port 10 or
11 and designates the A-field and B-field buttons.
The other overlay fits over the buttons of the
console Installed at adjunct port 10 or 11 and
designates the C-field buttons. Full size copies of
the programming overlays are included at the end of
this chapter for use if needed.
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.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.
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.
A complete or a partial printed record of the COS
program values can be obtained with a serial data
printer connected to the 
SMDRoutput lines of the
KSU. Complete details concerning this procedure
are included at the end of this chapter.SPECIAL PROGRAMMING
REQUIREMENTS
SINGLE-LINE KEYSETS
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 
Keyset 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.q
When the system is strapped for the muttifunction
(hybrid) system configuration, originating outside
calls with a Single-Line Keyset requires that one or
more lines must be programmed into a line group.
In order to receive outside calls on a Single-Line
Ketyset, 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. Aftemately it can be
programmed to have the prime line automatic
feature with ringing enabled at the prime line.
3-1 
						

							REUSED 8 LINE BLF KEYSET
Even though an 8 Line BLF 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 8 Line BLF 
Keyset.
The station port to which it is connected must be
programmed for a 3 and 8 Line 
Keyset.
The paired station port must be programmed for an
8 Line BLF 
Keyset atthough 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.
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 buttons of the 8 Line BLF
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 the 8 Line
BLF Keyset.
CLASS OF SERVICE PROGRAMMING WITH A
40-BUTTON OR A 32.BUT-TON CONSOLE
The system will recognize either a C42 through C49
from a 
40-button console or a HOLD, 1 through
HOLD, 8 from the 
keyset as the same programming
buttons. Because of this, it is possible to program with
a 
32-button console installed at adjunct port 10 or 11.
The programming buttons C42 through C49 (normally
provided by a 
40.button console and not available on
a 
32-button console) are relocated to the keyset as
follows:

							TOLL RESTRICTION PROGRAMMINGIn order for toll restriction to take effect, the following
three-fold process must occur:
One or more toll tables must be entered.
Toll tables must be assigned to all appropriate lines.
Toll tables must be assigned to all appropriate stations
Only the toll table(s) which are entered and assigned
to both a line and a station using that line will involk
any toll restriction. Toll tables 1 and 2 have entries
defauted in them and these tables are assigned to all
lines by default. These tables are not assigned to
stations by default.

TABLE ENTRY PROCEDURE
Determine the types of dialing restrictions which
must be imposed on the system. Typically, this
includes access codes which result in toll charges,
and certain local numbers as desired.
If the restricted dialing codes will be imposed
consistently on most or all stations in the system,
list them on one or two tables. If wide variation in
the dialing restrictions is planned, spread the
listing out across several tables.
Strategically group the listings on the tables so that
a list of restrictions can be applied to a particular
station or group of stations.
Designate each table as a DENY table or as an
ALLOW table. The numbers entered in a DENY
table are prevented from being dialed. ALLOW
tables take precedence over DENY tables.
Therefore, an entry in an allow table will provide an
explicit exception to an entry in a DENY table.
Note that the system always permits the dialing of
any number not explicitly denied. Also, system
speed dial numbers will not be toll restricted unless
specified by station COS programming.
Example A: Provide a simple and broad toll
restriction format by creating a DENY table with
two entries: ENTRY (1) 
= 1 ENTRY (2) - 0.
This format prevents all long distance and
operator calls.
Example 8: Prevent the dialing of all numbers
within the (804) area code, while allowing the
dialing of one specific number within that area
code, by entering 1804 in a DENY table and
18049782200 in an ALLOW table.
Enter the 
## character in place of a particular digit
to condense a range of numbers into one entry.
The # character is a “match-anything” digit, and
6.Since ft is important that emergency numbers
never be restricted, 
atways create an allow table
with entries of 911 and 1911 to override any DENY
tables that have been created.
7.
8.If the system is installed behind a PBX, include an
access code as part of every table entry.
Once these tables are completely filled out, enter
the restriction planning tables on the line, and
station programming reference charts to record the
planned toll restrictions for the system.
