7.1. What is saving automat?
The goal of the saving automat is find the optimal output line for
called number. The LCR process has several phases:
Input normalisation: transformation of the
numbers of calling and called participant into
so-called normal form before the input into the
saving automat.
Searching of normalisation: the destination
means the target side of the call. The part of
the destination is Route and manner of passing
of individual lines in the Route. The Route is
searched according to prefix of the called
normalised number.
Searching of Route: by the Route means the
logical assembly of lines. The part of the
Route is also time limit of the path validity
within particular days of week.
Searching of line: the path may consist from
one or more lines. The line, to which the call
will be at last switched, is determined
according to selected algorithm of line choice.
There are three methods of the search: 1) first
free – finds first free line, 2) cycle – search for
free line with oldest time of the last call, and
3) free minutes – uses free line with highest number of remaining
free minutes. Proper operation of the method requires setting of
tariffs for relevant lines.
Output normalisation: transformation of calling and called
numbers into normal form before switching into output line.
Check of prohibited numbers: after output normalisation and
before switching into found output line, the table of prohibited
numbers is searched for and in case of compliance the call is
refused.
