least cost routing

[REL4]

hi, anybody could tell me how exactly works te lcr?
i mean...
i know the comands to program it but, which table do i have to use at any time, which is the relation between the tables? when i have to use one or another?
ent ,dnt1, dnt2, pnr,frct,rct,etc...

DNT2 is where most entries should reside, DNT1 are the more specific entries that will overide DNT2, and FDT is the table where the Entry gets it's final destination code:

i.e.

LCDDP:TAB=DNT1;
LEAST COST DESTINATION DATA
EXCEPTIONS TABLE
ENTRY TRC PRE ACCT FRCT TOLL CBCS BTON TNS OSA
9118 7 118707 0 4 111111111111111 0
END
/* SUCCEED 18:16:02 */
/* MML_TTY_COMMAND 18:16:05 [LONSWB01] Ericsson */
LCDDP:TAB=DNT2;
LEAST COST DESTINATION DATA
NUMBER TABLE
ENTRY TRC PRE ACCT FRCT TOLL CBCS BTON TNS OSA
91 1 0 5 111111111111111 0

END
/* SUCCEED 18:11:07 */
/* MML_TTY_COMMAND 18:11:12 [LONSWB01] Ericsson */
LCDDP:TAB=FDT;
LEAST COST DESTINATION DATA
FICTITIOUS DESTINATION TABLE
FRCT TZONE PRE
4 1 7204
5 1 7205
END

In this example all calls starting "91xxx" will go to DNT2 to be resolved, there they pick up FRCT 5 which sets the the Destination to 7205.
The exception is "9118" which is found in DNT1 (this table is always checked first), So when "9118" is dialled, it is found in DNT1 where FRCT 4 is used which in turn selects a different route choice and destination code.

[tt]The order in which a number is analysed is
like this

LAC CODE DIALLED

|
|
+---------+
| ENT |
+---------+
|
|
+---------+
| NLT |
+---------+
|
|
+---------+ +-------+
No match | DNT1 |------->| |
goto dnt2 +---------+ | |
| |FDT |
| | |
+---------+ | |
No match | DNT2 |------->| |
goto RC +---------+ +-------+
or lim data | |
| |
|<-----------------+
|

Route Choice ,if no match use lim data .

Hi Syar!

Why you draw a down line going from a DNT2 box (to RC or LIM data)?
Whether I can use this LCR property?

For example:
"7" is fully for LCR in NADAP;
in DNT1 I route "781" to dummy DEST 001;
in DNT2 I route "78" to dummy DEST 002;
in RODDI I initiate "001", "002" and "7".

What will happen if dialled number will be 73xxx?

" Why you draw a down line going from a DNT2 box (to RC or LIM data)? "

Explanation:
e.g
7 is numtyp LC in NA .
RODDI:dest=001,rou=1,srt=4;
LCLDI:LIM=1,AC=1,DEST=001;
User dials 712345678
Number has no match in DNT1 , analysiz continues in DNT2 .
Number has no match in DNT2 either .
The LC analysis finishes to
The call use the dest (default dest) spesified in LCLDI .
Dialed number 712345678 will then go
out unmanipulated on rou=1 as it
after LC analysiz defaults to dest 001 via LC-limdata .



Thats why the line is there ..

Thnx Syar for your explanation.
