CHAPTER 3
APRIL, 1990
OCC (Other Common Carrier) Code Parameter
If a station is assigned a table with the OCC Flag set,
the system will allow the station to dial 10. To allow
the station to choose a particular carrier the table
assigned must have the 3 digit OCC identification code
entered. This assignment allows only certain OCC
codes to be used by restricted stations.
Code Numbers Parameters
Each of the systems’ 32 tables contain eight entries for
digit entry. Each item can hold an area code (3 digit)
and/or office code (3 digits). Area or office codes to be
restricted are placed in deny tables. Area codes or office
codes to be allowed are placed in alloWablea.
To simplify the understanding of Code Restriction on
the Electra Mark11 system, the discussion will be
divided into the following sub sections:
