Prerequisites

The number series for the LCR access code must be initiated.

The Least Cost Routing Class of Service (LCR COS) must be initiated for extensions and incoming tie lines. For PBX operators, LCR COS is set to the least restrictive level by default.

External destinations that include affiliated route choices, OFF-HOOK Queuing threshold levels, LCR-only-indicator, and terminating area code number must be initiated.

Note: If the external number length is not set with the command number_data_initiate (see the operational directions for NUMBER ANALYSIS, NA), the number length used in the Number Length Table will be calculated through the whole LCR analysis using the prefix/truncated digits. The calculated number length will then be used as the external number length in the external analysis.

Every external destination in the fictitious destination table must be initiated as an external destination (ED).

The Least Cost Routing facility must be initiated.

When the table is in use, a system time must be provided. If not, the default value for Time-zone/Day-group is used.
