8.3 Numbering Extensions and C.O. Lines

Once the OfficeServ 7400 system is booted, the MP40 and LP40 modules verify the mod-

ules mounted in each slot and save this information as the default configuration of the sys-

tem.

Depending on the settings of the S2 switch (SW6, SW7 and SW8) of the MP40 module, the sys-

tem assigns three or four digits to C.O. lines, extensions, and extension groups. Refer to 3.2

Mounting Control Modules, for details of setting the S2 switch.

C.O. line numbers from 701 (or 7001) are assigned sequentially to the C.O. line module

mounted in slot 1 of the basic chassis; numbers are then continuously assigned to the next

module in the next slot. This numbering process continues until C.O. line numbers are as-

signed to all C.O. lines. However, only the numbers from 701 to 799 are assigned when using

three digits. For example, if two 8TRK modules are mounted in slots 1 and 2, 701 is as-

signed to the first port of slot 1 (C1/S1/P1) and 712 is assigned to the 4th port of slot 2

(C1/S2/P4). That is, the 12th C.O. line is assigned to the 4th port of the 2nd slot of the ba-

sic (1

) chassis.

Extension numbers from 201 (or 2001) are sequentially assigned to the extension module

mounted in slot 1 of the basic chassis; numbers are then continuously assigned to the next

extension module in the next slot. This numbering process continues until the extension

numbers are assigned to all extensions. However, only the numbers from 201 to 349 are as-

signed when using three digits.

The last port of the first 8DLI or 16DLI2 module is assigned to the attendant group as de-

fault. All C.O. lines ring this attendant extension unless the default value is changed. Thus,

a phone with an LCD panel should be connected to the last port of the first 8DLI module.

Numbers between 500-549 (or 5001-5049) are assigned to an extension group.

The numbers of C.O. lines, extensions, or extension groups can be changed using MMC

724.
