4.3.9.1.2 LCR Leading Digit Table — PGM 221
The Leading Digit Table is used to analyze the user-dialed digits to determine an appropriate Digit Modification
Table Index. LDT Tables are provided for 32 LDT Table for iPECS-1200, 10 for the other systems.
The Table is divided into bins. The applicable LCR Access Modes (LCR Type) and the digits (up to the first 12)
to be compared with the number dialed by the user are entered in the Leading Digit Table bin.
In addition, indices to the Digit Modification Table are defined for each Time Zone of each Day Zone; refer to
LCR Control Attributes PGM 220.
Note the mode used to access LCR must match the LCR Type and must be within the effective LCR Access
Mode assigned in PGM 220 to access the Digit Modification Table index. The allowed LCR Types are:
CO Line or Loop access: User dials CO Line Access Code, CO/IP Group Access Code (8xx), Any
CO Line Access Code ‛9’, or presses a CO Line, CO/IP Group, or Loop button.
Internal: User dials outgoing call while receiving Intercom dial tone with no CO/IP access code.
Both: Both COL and Internal.
In addition, each Leading Digit Table bin has the option to require an authorization code entry. When the user-
dialed digits match an entry in the LCR Leading Digit Table, the system will check the Authorization option for
the LDT Table bin. If the Authorization option is enabled, the user must enter a valid Authorization code to
place the call.
Press the [Save] button to store the data entry. Note, as the data is stored,
the system sorts the LDT bins in ascending order to allow rapid “look-up”
of data. Thus, the bin number will be changed appropriately.
This entry defines the LCR modes that will
apply to this Leading Digit Table bin. To
apply the DMT index, the LCR Type must
be part of the LCR Mode defined in PGM
220.
