NEC IPS Basic LCR

Programming syntax = > = de (data end), => = change to…. EX: 050>04>15: =>12 EXE.

For this example we will be using PRI trunks in trunk route 10 as the first choice and POTS

trunks in trunk route 20 as the second choice. We will be dialing 7 digits for local calls and 11digits for long distance calls. The home area code is 214. There are 3 LCR tables available (5, 6

& 7) with a special table used for CCIS networking. We always use table 5 for the main LCR.

Programming Procedure

8AA000> 0> 4005 EXE = assigns LCR group number 0 to LCR development pattern table 5.

8A4005> 2> 0000 EXE = any local number dialed beginning with 2 will use route pattern table

number 0000.

8A4005> 3 ~ 8> 0000 EXE = add remaining local office codes.

8A4005> 90, 92 ~ 99> 0000 EXE = break out 911 for emergency calling.

8A4005> 910, 912 ~ 919> 0000 EXE = break out 911 for emergency calling.

8A4005> 911> 0011 EXE = this places 911 in a table by itself for emergency calling. All other

local dialed numbers use the same table number 0000.

8A4005> 12 ~ 17, 19> 0001 EXE = this places long distance numbers in a different table than

the local numbers. This is to set up for possible future dialing restrictions.

8A4005> 1800, 1855, 1866, 1 877, 1888> 0008 EXE = this places toll free numbers in adifferent table for possible future dialing restrictions.

8A4005> 1801~1809, 181~184, 1850~1854, 1856~1859, 1860~1865, 1867~1869, 1870~1876,

1878~1879, 1880~1887, 1889, 189> 0001 EXE.

8A4005> 011> 0012> EXE = international numbers.

8A4005> 11> 0010 EXE = See special case for 911 calls. 9 must be added in for proper routing.

8A0000> 1> 00010 EXE = references table 000 and uses trunks from trunk route 10.

8A0000> 2> 00220 EXE = references table 002 and uses trunks from trunk route 20 if all trunks

in route 10 are busy.



from route 10 are busy.

7/17/2019 Basic LCR



8A0011> 1> 01120 EXE = references table 011 and uses POTS trunks from route 20 for 911

calls.


8A0012> 2> 01420 EXE = references table 014 and uses trunks from trunk route 20 if all trunksfrom route 10 are busy.

Special Case for 911

8A4005> 11> 0010 EXE



in route 10 are busy.

8A5020> 100> 9000 EXE = add additional digits in front of the number dialed. The digitsspecified are found in table 9000, command 8A9000.

8A9000> 0> 9 EXE = add 9 in front of the number dialed.

855> 2 ~ 8> 24=> 07 EXE = allow maximum digits of 7 on local numbers dialed to speed up

dialing.

855> 90, 92 ~ 99, 910, 912 ~ 919> 24=> 07 EXE = fill in the remaining numbers.

855> 12 ~ 19> 24=> 11 EXE = allow maximum digits of 11 on long distance numbers dialed.

855> 911> 24=> 03 EXE = allow 3 digits dialed for 911 calls. This gets the call out faster.

855> 11> 24=> 03 EXE = to speed up dialing.

855>0 1> 24=> 18 EXE = allows 18 digits for international numbers. If the number of digits is

less, a short delay in dialing will be experienced. The system is waiting to see if more digits up to

the maximum of 18 will be dialed.

By now you may have noticed that previous table numbers actually reference the next command

to be used.

EX: 8AA000> 0> 4005 EXE

8A4005> 2> 0000 EXE

8A0000> 1> 00010 EXE

8A5000> 100> 9000 EXE

7/17/2019 Basic LCR



8A9000> 0> 9 EXE

The tables chosen do not have to be in numerical order. You can use any table number allowed

in the range provided as long as you reference it properly moving to the next command. Each

command adds information required to process the number dialed and get it out of the system to

Telco facilities. There will be cases when we need to add digits, strip digits or restrict digits. Agood practice is to put the database on paper before programming it into the system.

Last Step

Assign a spare access code to test the LCR program.

EX: 200> *2> A126 EXE. This sets up *2 as the LCR access code for LCR table 4005. Dial *2

plus your test numbers to test the program. Once you are satisfied that it is working properly, go

back to CMD 200.

EX: 200> 9> 100=> A126 EXE. This changes dial 9 from a direct route access code to the LCRaccess code. The users will probably not notice the difference. If there are issues with your

program simply change 9 back to a route access code and use your test code to trouble shoot the

program.

Delete 1 From Number Dialed

Some carriers may require 10 digits dialed; however the users are trained to dial 11 digits. Using

the LCR tables we can delete the lead digit 1 from the number dialed.

8A4005> 12> 0001 EXE

8A0001> 1> 00110 EXE

8A5001> 151> 1=> 0 EXE = delete area code dialed.

8A5001> 153> 00=> 01 EXE = delete only one digit from the area code dialed.

EX: the user dials 12145551212. The system sends 2145551212 to the CO.

Add Digits to Number Dialed

Some carriers may require area code added in for local calls. The user still dials 7 digits.

8A4005> 2> 0000 EXE

8A0000> 1> 00010 EXE

8A5000> 100> 9001 EXE

7/17/2019 Basic LCR



8A9001> 0> 1214 EXE = this adds 1214 to all local dialed numbers. The user dials 222-1212.

The system sends out 12142221212 to the CO.

Additional Data For PRI’s

Some carries require additional program data to complete calls on their service. Within the8A5XXX tables there are options provided to match the settings to the Telco requirements for

PRI’s.

EX: 8A4005> 12> 0001 EXE

8A0001> 1> 00110 EXE = route 10 = PRI trunks.

8A5001> 157> 00 EXE + 8A5001> 158> 00 EXE = CPN identifier plan of UNKNOWN, or

8A5001> 157> 01 EXE + 8A5001> 01 EXE = INTERNATIONAL, or

8A5001> 157> 02 EXE + 8A5001> 158> 01 EXE = NATIONAL, or

8A5001> 157> 04 EXE + 8A5001> 158> 01 EXE = LOCAL

8A5001> 163> 01 EXE = SDN, or

8A5001> 163> 03 EXE = MEGACOM

The most common settings are 157>02, and 158>01, however

many times this is a trial and error assignment. You may also need a different setting for long

distance vs. local vs. 1800 vs. international numbers. Try each combination of settings and dial

all of your test numbers for each setting to determine which one works for the type of dialednumber.
