008 MLX, 016 MLX (Release 7.0 and later systems), 408 GS/LS-MLX,
and 408 GS/LS-ID-MLX Modules. Two extension numbers are assigned
to each physical extension jack: the first for an MLX telephone and the
second for any equipment connected to the telephone through an MFM,
ISDN terminal adapter, or any 2B data desktop video endpoint.
008 OPT Module. The system recognizes this module as an 012 (T/R)
module. Therefore, even though the OPT module has only 8 physical
jacks, it uses 12 ports of capacity. An extension number is assigned to
each of the 8 physical jacks and to each of the four "phantom" jacks.
This section contains instructions for calculating the system's extension capacity
according to the number of certain module types.
Planning Form Instructions
1. In the table under the Extension Capacity section of Form 1, fill in the
number of each type of extension module on the appropriate line of the
Number of Modules column.
2. Add the column and record the result at the bottom (System Totals line).
3. For each module, multiply the value in the Number of Modules column by
the value in the Physical Jacks per Module column and record the results
on the appropriate line in the Physical Jacks by Module Type column.
4. Add the column and record the result at the bottom (System Totals).
5. To determine the number of extensions assigned for each module type,
multiply the value in the Physical Jacks by Module Type column by the
value in the Extensions Assigned column and write the results in the
appropriate row in the Total Extensions Assigned column.
6. Add the column and record the result at the bottom (System Totals).
Each 100D module is assigned 24 logical IDs, even though the
module has only 1 physical trunk jack.
Each 800 NI-BRI module is assigned 2 logical IDs per physical trunk
jack for a total of 16 logical IDs.
NOTE:
Since the system assigns an additional four extensions to each
008 OPT module, you must first calculate the Extensions Assigned
by multiplying the number of 008 OPT modules (noted in the Number
of Modules column) by 4 and then add this subtotal to the number
noted in the Physical Jacks by Module Type column.
