IV.15. LEAST COST ROUTING (8006)
Allows setting the system to check the numbers dialed by extensions to find the
most economical route for establishing the calls.
When an extension activates Automatic Line Access by dialing “ 9 ”, instead of the
C.O. dial tone, he receives the internal dial tone. Then, the system compares the
digits he dials with the pre-programmed prefix table and as soon as it finds a match,
it calculates the most economical route based on the pre-programmed parameters.
After such a match is found, a line is selected (it may be a specific line related with
the prefix or any idle line) and a prefix of at most 4 digits (if present) is added in
front of the digits extension dials and this number is sent to the C.O. If no match is
found, any idle line is accessed and the number is sent to the C.O., after the 6
th
digit
is dialed.
IMPORTANT
It is not recommended to use this program unless necessary (if more than one
operator with different rates are not available in your country).

All information for LCR is stored in a 40-row table.
L : Location number (01,…, 40).
P : Prefix (at most 6 digits) that the system compares with the
dialed digits.
Q : Prefix (at most 4 digits) that the system adds in front of the
dialed number.
R : Line number through which the external number with prefix Q
is dialed (01,…,04).
S : The starting and ending hours of LCR.
T : Day information (0,…,8).
U : Indicative charge pulse period in seconds (000,..,250).
As can be seen, each location in the LCR table starts with a prefix (at most 6
digits) that will be compared with the first 6 dialed digits. The second parameter
is again a prefix (at most 4 digits) that the system will add in front of the dialed
numbers. The third parameter determines if dialing should be made via a
specific line. The fourth parameter is the starting and ending hours of the time
period. The fifth parameter is the day info. A specific day, weekday or weekend
may be programmed. The last parameter is the pulse period info, which may be
used for selecting the route costing least. The number entered here is the pulse
period in seconds and the highest means the cheapest.
1. Parameter L:
a) At most 40 different locations can be defined.
b) Dialing
“

” and then hanging up clears the specified location.
