DR
LCR begins with the receipt of a dial string from a facility capable of originating an outgoing call: station,
automated attendant, Tie trunk, DISA trunk, DID trunk, etc. The dial string is identified as an LCR call by
the presence of the LCR Feature Access Code—typically
remaining external digits are processed.
Route Analysis
Route Analysis chooses a Route Plan based on the dialed digits. The Routing Analysis Plan becomes the
index into the time/date calculations described in the next section. If the Strata CTX is unable to match the
dial string, it uses the default route plan which assures a route out of the system. If a match is found, Strata
CTX determines if a exception table is associated with the dial string. If the dial string appears in the
exception table, the call is assigned to the Route Plan stored in the exception table. Otherwise, the Route
Plan stored in the initial table is used.
Time of Day
The Strata CTX maintains time and day values for LCR separate from those for the general system. One
day can be divided into three zones, and each day can be categorized as a Weekday, Weekend, or Holiday.
Connection
Selection of a Route Choice Table begins the process of actually connecting the call to an outgoing trunk.
Each Route Choice Table consists of six Route Definitions which operate in terminal hunt fashion to select
an OLG and to apply a digit modification treatment.
