EXCEPTION TABLES PROGRAMMING 
640.1 INTRODUCTION 
Programming Steps 
The 2448EX Hybrid Key Telephone System offers a 
flexible means of applying toll restriction to stations 
or indiiduak. Dialii privileges (or toll restriction) 
is determined through assignment of station and CO 
line Class Of Service (COS). Several types of re- 
striction can be derived simply by programming COS 
assignments and CO line access to stations. This 
may, in some cases, be all that is necessary. How- 
ever, when a more complex or specific type of re- 
striction is desired the system offers two allow and 
two deny tables along with four special tables. 
These tables can be programmed in a variety of 
ways to handle applications that are straight fonvard 
or applications that require a more complex arrange- 
ment. 
The allow and deny tables are assigned to stations 
based on their station Class of Service (COS) as- 
signment. The Station (COS) interacts with CO tine 
COS assignments to provide several different types 
of dialing privileges (Refer to CO/Station COS matrix 
below). 
The Allow and Deny tables allow entries of either 
general or specific allow and deny codes such as 
allowing all [I -8001 type calls, an&or denying all [I]+ 
or [O]+ calls. The allow and deny tables allow a 
maximum of eight digits to be entered as allow or 
deny digits. This allows for entry of certain area 
codes or office codes or a combination of area code plus office code that can specifically be allowed or 
denied. For example the code [I 5551212] may be 
entered in the deny table to deny local toll informa- 
tion calls. Each allow table contains twenty (20) bins 
for entry of allow codes. The deny tables allow for 
ten (10) entries of deny codes, in each table. 
The following rules should be remembered when 
setting up the Allow/Deny tables (Refer to Table 
640-2). 
1. 
2 
3. 
4. If both tables (allow and deny) have no entries, 
no restriction is applied. 
If entries are made in the allow table and only 
there, then only those numbers are allowed. All 
other dialing is denied. 
If entries are made in the deny table and only 
there, then only those numbers are denied. All 
other dialing is allowed. 
If there are entries in both allow and deny 
tables, the allow table is searched first and if a 
match is found, it is allowed. If a match is not 
found, the deny table is searched and if a match 
is found there, the call is denied. If the number 
does not match an entry in either table, it is 
allowed. 
A special “Don’t Care” (“D”) character may be en- 
tered as a digit to either allow or deny any digit dialed 
in that digit sequence. For example a code [I ‘D” O] 
and [I “DO” I] may be entered in the deny table which 
would allow local long distance calls (numbers dialed 
with a 1 followed by a seven digit local number), but 
would deny long distance calls (numbers dialed with

a 1 followed by an area code). 
The 2448EX system also offers four (4) special 
tables that can be referenced from within the two 
allow tables. Three of the special tables can be 
assigned to specific 
area codes that require further 
toll restriction definition. The fourth special table is 
reserved for use as 
a home area code table (num- 
bers within the same area code as the site where the 
system is installed). This provides expanded ability 
to apply toll restriction on numbers that are dialed 
within an area code. Each special table will allow up 
to (800) entries (200999). This offers the ability to 
allow every office code on an individual basis 
640.2 RELATED lTEMS TO TOLL RESTRIC- 
TION 
A. CO/PBX Lines 
When CO lines are marked as PBX lines (refer to 
CO line programming, Sec. 620) the system will first 
check the PBX code table (refer to sec. 610.17’) for 
a valid match. If the first digits dialed do not match 
the entries in the PBX code table the call is consid- 
ered an attempt to call another PBX extension and 
no toll restriction is applied. If the first digits dialed 
are found in the PBX code table then toll restriction 
will start with the next dialed digit. 
B. Forced Account Codes 
The system can optionally force the use of account 
codes on all restricted calls. When forced account 
codes are enabled (see sec. 610.20) an account 
code must be entered to place a call that is otherwise restricted through toll restriction. By entering an 
account code the stations effective class-of service 
becomes that equal to class of service 1 (unre- 
StriCted). 
When account codes are forced on a system wide 
basis selected users may be instructed on how to 
enter account codes from any station and be allowed 
to dial unrestricted from a station that may otherwise 
be restricted. Use of account codes in this manner, 
as a traveling class-of-service, is however not con- 
trolled by the system. Any station user with knowl- 
edge of how to 
enter account codes to override a 
stations toll restriction will be allowed to do so. 
C. SLT DTMF Receivers 
When single line telephones are connected to the 
2448EX system and toll restriction is enabled the 
system DTMF receivers located on the APB board 
will monitor the call for a programmed period of time 
(refer to SLT Receiver Timer, Sec. 610.38). While 
the DTMF receiver is monitoring the digits being 
dialed, by 
a single line telephone, it is considered 
busy and not available for monitoring another SLT 
attempting to dial. When all DTMF receivers are 
busy, an SLT attempting to go off-hook will not 
receive dial tone until a receiver is available. The 
system has up to six (6) DTMF receivers (two (2) 
standard 
on the APB and four (4) optional on the 
SLU) for monitoring SLT dialing. If 
a system has 
heavy SLT usage toll restriction may inhibit dialing 
by SLT stations. 
Two options are available to help alleviate this prob- 
lem; 1) shorten the SLT receiver timer(see section 
610.38). This will free up DTMF receivers faster, 
however, may not provide the desired toll restriction 
for SLT stations: 2) Enable LCR and force LCR on 
SLT stations. When the LCR data base is set up the 
three digit table allows for entry of the number of 
digits to be expected. When a SLT dials the appro- 
priate number of digits LCR will release the DTMF 
receiver and then be available for another SLT call. 
D. LCR VS. Toll Restriction 
LCR is not intended to. be an alternative to toll 
restriction 
nor is toll restriction intended to be a 
alternate to LCR. In fact they both work best when 
programmed together. Toll restriction provides the 
dialing privileges that stations are allowed and LCR 
provides the routing of calls onto the proper type of 
lines. LCR can enhance toll restriction in that LCR 
provides a “Store and Forward” operation that allows 
the system to analyze the digits being dialed before 
a trunk is seized. This prevents users from by-pass- 
ing toll restriction by taking advantage of the time it 
takes for a central office line to provide dial tone. 
Because of this it is recommended that LCR be 
considered when toll restriction is desired.

643.3 TOU RESTRICTION PROGRAMMING 
A Entering Toll Table Programming 
Programming Steps 
If the system is in the programming mode, continue 
using program codes. If starting to program here, 
enter the programming mode first (See Paragraph 
600.3) 
NOTE: It is recommended tiat the Exception Tables 
be initiakedpriar to entering data into the tabks. Do 
this by rollowing the instructions in Sec. 600.4 for 
initialking the Ekeption Tables (Flash 73). This 
procedure may also be repeated if it is cktermined 
that&a in the exception tables has become cvmfpt 
However, after initialking the exception tables, for 
this purpose, all data must be m-entered into the 
tables. 
1. Press FLASH and dial [60]. The following mes- 
sage will be shown on the display phone: 
-- 
1. 
2. To program allow / deny tables press the ap- 
propriate button and enter information as out- 
lined in the following procedures. 
3. To program special tables 1-3 it is necessary to 
associate an area code to the table. Do this by 
pressing the appropriate “AREA-X? button and 
assign the area code. 
NOTE: Special Tale 4 is reserved for the home area 
code and does not require a area code entry. 
4. To display entries in any of the tables press the 
DISP button (button #9). Entries in the allow / 
deny tables will display two at a time. Entries 
in the special tables will be displayed six (6) at 
a time in ascending order. Description 
All toil tables have been conveniently placed under 
one program code to allow entry of all toll restriction 
data. When entering toll information the buttons on 
the phone will be mapped as follows: 
When the system searches the allow and deny 
tables, the entries are looked at starting at Bin 01 
and proceeding sequentially through the table to the 
last bin. In addition, the allow table is always 
searched before looking at the deny table. There- 
fore the order of entry is important. Entries that are 
specific (i.e. (1 716J) should be placed ahead of 
entries that are more general (usually include ‘Don’t 
Care” digits i.e. [i ‘D” 11). 
Once a match is found, in the allow table, that 
references a special table the number dialed will be 
checked for an allowed code in the special table. If 
a match is not found in the special table the system 
will continue to check for a match in the next allow 
or deny table that is to be checked. The system will 
not return to the table that sent the call to the special 
table.

B. Allow Table Programming 
Programming Steps 
1. Press the ALL-A or ALL-B flexible button (But- 
ton #I or #3). The following display will be 
shown on the display telephone: 
The first two bins locations are displayed. 
2. Dial on the dial pad the twodigit bin number 
(01-20) the allow code is to be entered into. 
NOTE: It is recommended that; bin 17 be reserved 
for an entry that will reference special table number 
1; and bin 18 be reserved for an entry that will 
reference special table number 2; and bin 19 be 
reserved for referencing special table number 3; and 
bin 20 be reserved for referencing the Home area 
code table, special table number 4. 
3. Dial the allow code where: 
0 to 9, 
l , # = corresponding allow digits (numbers) 
DND = Don’t Care digit (“0”) 
TRANS = search special table (“S”) 
4. Press HOLD button after each entry. 
5. When all entries for one table are complete, 
press the flwible button for the next table. 
r~ The following rules shoukf be applied when making 
entries that will reference the special tables: 
I. For entries referencing the first three special 
tables 
a specific area code must be identified 
(one for each table needed). Then make note 
as to how the numbers will be dialed when 
dialing numbers to this area code (i.e. with a 
leading digit [l] or no leading digit [l]). The 
entry into the allow table would be entered as 
follows: 
Leading digit [1] - BB I XXX DDD (S} 
or 
Non Leading [l ] - BB XXX DDD {Sj 
Where; 
BB - Bin number (recommended 17-19) 
XXX = Area code (must match AREA-X entry) 
DDD = ‘Don’t Care” digit (three entries, DND button) 
(S}= Search Special Table Command 
(TRANS button) Description 
Allow Table - Each Allow table contains twenty (20) 
bin numbers. Each bin number may be up to eight 
(8) digits in length including {Don’t Care} digits and 
{Search Special Table} commands. Entries into the 
allow table represent exceptions to numbers or 
codes that are to be allowed only if they would 
otherwise be restricted by an entry in the deny table. 
For example if [ 1 555 12121 is to be allowed but [I +] 
numbers are denied, by an entry into the deny table, 
then [1 555 12121 should be entered into the albw 
table as an allowed number. 
l Allow table A is referenced and searched first 
(before the deny table A) when Station COS is 
2 and CO line COS is either 1 or 2. 
. 
Allow table B is referenced and looked at first 
(before the deny table B) when Station COS is 
3 and CO line COS is either 1 or 3. 
l When station COS is 4 and CO line COS is 1 
both allow tables are looked at first (allow table 
A first then allow table B) then both deny tables 
(deny table A first then deny table B). 
Don’t Care digits specify that the system should 
consider any digit dialed in that position as a match. 
Don’t Care digits should net be entered as the last 
digit in an entry, as this would be an unnecessary or 
meaningless command. 
Search Special Table commands must be entered 
in a specific manner and should always be placed 
as the last entries in the Allow table. lt is recom- 
mended that the last four bins (17-20) in the allow 
table be reserved for referencing the four (4) special 
tables with the reference to the home area code 
(special table 4) always being located in bin number 
20. Search Special table commands can only be 
entered into the allow tables. 
To erase a bin, enter the two-digit bin number follow- 
ing by pressing the HOLD button.

Programming Steps 
To program a special table it is first necessary to 
assign an area code to the table (except for the home 
area code). 
1. To assign an area code to a special table press 
the appropriate AREA X flexible button (button 
#/9-l 1). The following display will be shown on 
the display phone: 
Enter the three (3) digit area code. 
Press the HOLD button. The display will now 
update. 
To enter office codes into the special table 
press the ST-X flexible button (button #5 - #8) 
that corresponds to the area code programmed 
above. The following display will be shown on 
the display phone: 
Where: 
XXX= AreaCode 
5. Enter the three (3) digit office codes that are to 
be allowed followed by a [I] which means to 
allow this code. To remove a code from the 
allow list enter the three (3) digit office code 
followed by a [0] which will remove the code 
from the allow list. 
XXX [l] = Allow code 
XXX [0] = Remove code from the list 
Where XXX = an office code from 200 to 999. 
6. Press enter after every code entered. Multiple 
codes may be entered in a row. The display will 
update showing the first six codes in ascending 
order. 
Description 
The special tables provide greater flexibility in de- 
signing a toil plan for a particular site. Each special 
table allows entry of up to 800 three digit oftlce codes 
(200 - 999). Three of these tables must be assigned 
an area code by which they are referenced. the 
fourth table is reserved for the home area code and 
requires no area code entry. 
The special tables are referenced through entries in 
the allow tables. Four area codes, including the 
home area code, can be referenced to these special 
tables for further definition. When a special table is 
referenced, entries must be made in the special 
table specifying what office codes will be allowed. 
Codes can be added to the allow-list or-rem&d from 
the list. When a special table is checked for a match, 
to a three digit code, but not found the system will 
then continue to search the next allow deny table that 
is to be checked. The system does not return to the 
allow table which routed the call to the special table. 
Default: By default no codes are on the allow list.

SECTION 650 
LEAST COST ROUTING PROGRAMMING 
A. Introduction 
Least Cost Routing (LCR) selects the most economi- 
cal programmed route for an outgoing call. When a 
station user dials an outside number, the LCR fea- 
ture analyzes the number and then automatically 
chooses an outside line from the group that has been 
programmed as most economical. The LCR feature 
puts the responsibilii of choosing the least expen- 
sive route for each area code and exchange code on 
the system administrator, not on the station user. In 
order to make 
a routing decision, the LCR feature is 
programmed in the system database. The success- 
ful operation of this feature is completely dependent 
on the accuracy of the programming. 
There are eight (8) different tables which are set up 
to monitor the dialing of digits and to select the best 
route for the call depending on time of day and day 
of week. 
.- 
 These tables are: 
Three (3) Digit Area/Office Code Table 
Six (6) Digit Office Code Table 
Exception Table 
Route List Table 
Insert/Delete Table 
Daily Start Time Table 
Weekday (Weekly) Schedule 
B. LCR 
Operation 
The system first checks to see if the number dialed 
is more than two digits. If it is two digits or less, the 
call is processed according to instructions in the 
Exception Table. If the number is not found in the 
Exception Table, the call is denied. 
-1 If the number is more than two digits, it goes to the 
3 Digit Table. If the first diiit dialed is a ‘1” the 
leading 1 table will be checked with the following 
three digits if the first dffit dialed is not a “1” then 
the first three digits are checked against the Non- 
Leading 1 three diiit table. The first three digits 
(either office code or area code) are then checked to 
see if they are in the 3 Digit Table. If they are not 
found there, the call is denied. If the digits are found 
in the 3 Digit Table, the system then checks for an 
entry to see if the 6 Digit Table must be referenced. 
If the 6 Digit column is marked (yes] in the three digit 
table entry, the number is then checked in the 6 Digit 
Table. There are twenty (20) six digit tables. Each six digit 
table is programmed and becomes associated to a 
specific area code with a selected route. Office 
codes are entered into the six (6) digit table that will 
be routed to a specifc route list table. This allows 
the system administrator to split area codes for 
muting to different lines connected to the system. 
This helps when Foreign Exchange lines (PX Lines), 
Banded WATS lines, or “Dedicated” Lines (OPx’s 
from another system) are in use. 
If the office code is not found in the 6 Digit Table, the 
call is referred back to the 3 Digit Table for selecting 
a route list table. And then goes through the same 
procedures as descnied below. 
Before actually selecting a route list table, the num- 
ber is checked against the toll restriction tables 
(station COS). When LCR is enabled, only station 
Class of Service is referenced. CO line Class of 
Service is no longer applicable. All CO lines are 
considered Class of Service I. 
If the call is not allowed through the toll restriction 
tables, the call is denied. If it is allowed, the call then 
goes to the Route List Table as specified by either 
the three (3) digit or six (6) digit table. 
The Time of day and Day of week is determined and 
the call is presented to the corresponding time period 
route within the specified route table. Bach of the 
sixteen (16) Route Tables contain four time sensitive 
mutes. Routes are determined by the time of day 
and day of week as specified in the Daily Start Time 
table and the Weekly Schedule table. 
After the appropriate route is selected, LCR Class of 
Service becomes applicable. A station can use only 
those line groups programmed with a priority number 
equal to or higher than the station’s LCR Class of 
Service. 
If a line is not available in the first choice line group, 
the system advances to the next choice line group 
and searches for a free line. This process continues 
until an available line is found, or the last available 
line group is searched ,or until a line group is reached 
with a priority assignment lower than the station’s 
LCR Class of Service assignment. 
When a line is available the system will seize that 
line and wait for dial tone. Then before dialing, the 
system checks the Insert/Delete table for digits that 
should be deleted from the front of the number or 
digits that should be inserted either before or after 
the number dialed. Finally the system begins to dial 
the number out over the selected line. All of this
