							1. INTRODUCTION 
1 .Ol This document has two main purposes: a) to 
describe the Least Cost Routing (LCR) and Toll 
Restriction (TR) features, and b) to serve as a 
supplement to Section 200-255-300, System Pro- 
gramming, in order to guide the service technician 
in LCRflR programming. Various examples, tables, 
and flowcharts are provided to clarify feature expla- 
nations. 
a .02 This document assumes that the reader is 
familiar with PERCEPTIONekex programming 
procedures and the mnemonics used with the LCR 
and TR data entry utility programs. 
2. GENERAL DESCRIPTION 
2.00 Least Cost Routing (LCR) 
2.01 
Least Cost Routing causes the system to 
select the least expensive trunk available for that 
particular time of day. The station user simply dials 
an LCR access code and the required telephone 
number. LCR will then select the optimally-priced 
route and automatically delete and/or insert any 
necessary digits (for MCI, Sprint, etc.) by analyzing 
the dialed telephone number (including area code 
and, in some cases, office code). 
2.02 The three variable time schedules per 24- 
hour clock allow the end-user to take advantage of 
rate variations during these hours. The various 
routing combinations for the three time schedules 
are contained in 15 Route Tables. Each table is 
selected as a function of the dialed telephone 
number. 
2.03 The LCR feature is compatible with and 
transparentto all other PERCEPTIONehex features. 
It is designed so that it is completely disabled until 
a simple parameter (LCR) is enabled in the System 
Data Block 
(DSYS Program). 
2.04 If a Direct Trunk Access code (not the LCR 
access code) is dialed, the outgoing call is handled 
as a normal direct trunk access call without using 
LCR. 
PERCEPTIONeh, 
LCR/TR PROGRAMMING GUIDE 
MARCH 1991 
2.05 LCR Data Blocks are separated from all other 
Data Blocks. It is unnecessary to change a com- 
pleted Data Block when adding the LCR feature to 
a system already in use, except to assign the LCR 
access code 
(DACD Program) or to enable LCR 
(DSYS Program). 
2.06 There are three LCR classes (LCI , LC2, and 
LC3), which allow specific stations to be denied 
access to the most expensive routes. LC3 is the 
lowest class; LCl is the highest. LC3 routes are 
always selected first, no matter what class the 
station is allowed. If all LC3 routes are busy, and 
the calling station is allowed LC2, the system will try 
to select an LC2 route in the order programmed. If 
LCl is allowed, and all LC2 routes are busy, the 
system will try to select an LCI route. 
l The Class of Service Data Block indicates the 
LCR class of that particular Class of Service. 
l A warning tone is received by the station user if 
the last choice route is selected (if the WTA 
prompt, PAR table, 
DLCI Program, is pro- 
grammed to Y). 
l If all the routes are busy, busy tone is received 
by the station user, who may then activate the 
Automatic Callback feature. The station will 
then be called when the first trunk in that sta- 
tion’s LCR class is idle. When the station 
answers the callback, the idle trunk will be 
seized and the telephone number will be auto- 
matically dialed out to the distant end. 
2.07 All of the above logic and the remainder of the 
Least Cost Routing and Toll Restriction features 
are described, and can be followed step-by-step, in 
the Detailed Logic Flowchart. Thisflowchartcan be 
used as a fault finding procedure for customer data 
programming, and to answer questions regarding 
what will happen when certain parameters are 
programmed in a certain way. 
2.10 Toll Restriction (TR) 
2.11 The Toll Restriction (TR) program causes the 
system to restrict (or not restrict) specific stations 
from calling certain area codes and/or office codes. 
2.12 Toll Restriction can be used for long distance 
toll restriction, for restriction in the local area (home 
area), or both. The TR class also decides whether  
						

							PERCEPTIONea, 
LCWTR PROGRAMMING GUIDE 
MARCH 1991 
to restrict calls to the local central office operator, 
international calls, and/or long distance directory 
assistance. 
2.13 Eight different TR classes (CLS 0 w 7) can be 
programmed in the previously-described manner. 
+I+ Also, CLS 8 restricts all I+ and a + calls. 
2.14 All stations programmed for TOL = NONE will 
have no restrictions. The TOL parameter (TR class 
number) is located in the 
DEKT, DSlT, and DTGP 
(TIECCSA Trunks) Programs. 
2.15 
Before a call via Least Cost Routing or Direct 
Trunk Access (DTA) is completed, the 
DTOL 
Program 
will decide whether or not the number 
being dialed is allowed. If not allowed, the originating 
station will receive overflow tone. If allowed, the 
call will be processed further. 
2.16 All of the above logic and the remainder of the 
TOL parameter are described, and can be followed 
step-by-step, in the Detailed Logic Flowchart. 
Example: 
Fpllow a call through the Logic Flowchati 
according to what is programmed in Example 
#2. 
3. NUMBERING PLAN (NORTH AMERICA) 
3.00 Description 
3.01 
All telephone systems in the USA and Can- 
ada use the North American Numbering Plan. All 
PERCEPTION,&,, LCR/TR features are based 
on this plan. 
3.02 The routing codes for Direct Distant Dialing 
(DDD) within the North American Numbering Plan 
consist of two basic parts: 
1) A 3-digit area code or Numbering Plan Area 
(NPA) code. 
2) A 7-digit telephone number made up 0f.a 3-digit 
central office (CO) code and a 4-digit station 
number. 
NOTE: 
When used together, these ten digits com- 
prise the network “‘address” or destination code for each telephone. 
l The first digit of the area code must be a number 
between 2 and 9. The second digit must be a 1 
or 0. The third digit may be any number between 
0 and 9. 
l The first two digits in the CO code must be any 
numbers between 2 and 9, except when inter- 
changeable codes are used (then the second 
digit can be any number between 0 and 9). The 
third digit of the CO code on all four subscriber 
numbers may be any number between 0 w 9

3.03 The following are exceptions to the rule: 
1) 
2) 
3) 
Service Code (Nli): This is used for various 
special local services and, when programmed 
properly, is recognized only as a service code. 
In this case, the system will act immediately 
after this 3-digit number is completed. 
Interchangeable Codes (ICC): In some areas, 
the second digit of the office code is allowed to 
be any number from 0 w 9. In this case, the office 
code may look like an area code (if the second 
digit is 0 or 1). If so, the PERCEPTlONe or 
PERCEPTIONex looks for a DD prefix (1) to 
identify whether or not the next 3-digit number 
is an area code. When ICC is used, 0 + a 3-digit 
number is always an areacode. When ICC is not 
used, the system identifies the area code by 
looking at the second digit of the first 3-digit 
number (if this digit is 0 or 1, the number is an 
area code; if not, the number is an office code).

service without a charge to the originating party.

The area code is always 800. 
In PERCEPTIONeLex LCR, this type of call 
can be programmed (in the PAR table) as 
either a regular DDD call with an area code 
of 800, or as a toll free 800 call, routed via the 
-2-  
						

							4) 
local call route table (LCR). 
Long distance directory assistance (555): This 
is a call using any area code (or no area code) 
plus 5551212. If allowed, this type of call is 
routed via the LDI route table, as indicated in the 
PAR table, or via the route table (DAC = N) to 
which this area code is assigned. 
NOTE: 
When a DDD callis dialed, 
needed before the area 
cause the local operator to be connected. 
4. SPECIAL COMMON CARRIER 
4.00 Description 
4.01 Dialing extra digits to access the Special 
Common Carrier (SPCC) trunks is not necessary if 
the LCR feature has been activated. The selection 
of SPCC trunks (like all other trunks) and the 
outpulsing of the extra digits (access code, authori- 
zation code, etc.), is accomplished automatically 
by the PERCEPTIONeLex LCR feature. This func- PERCEPTION,&,

tion is completely transparent to the station user. 
5. PROGRAMMING 
5.00 General 
5.01 Customer data programming can be done in 
many different ways with the same results. The 
starting point and the particular order may differ 
according to personal preferences. As an example, 
one logical sequence for programming customer 
data is shown in the Customer Data Programming 
Flowchart. 
5.02 For detailed information, 
see Programming 
Procedures, 
Section 200-255-300, in the 
PERCEPTIONekex Insfaallation and Maintenance 
manual, and the Logic paragraph in this LCR/TR
