2.2 Line Equipment Numbers (LENS)
The Line Equipment Numbers (LENS) are used to specify the location of a circuit (trunk/port) in any of
the PIM universal slots. Refer to the figures in this section, and confirm the LENS format used in the sys-
tem.
As shown in Figure 2-6, the LENs consists of six digits: two digits for MG, one digit for U, two digits for
G, and one digit for Lv.

2.2.2 Unit
Figure 2-8, which represents a fully expanded system, explains the Unit (U) numbers. The numbers
range from 0 to 3, and each unit represents the PIM universal slots, No. 04-12 (U 0/2) or No. 15-23 (U
1/3).

2.2.3 Group
The Group (G) numbers are allocated as shown in Figure 2-9. A total of two Groups are assigned on
each universal slots within the PIM. Slot numbers 10, 11, 12, 21, 22, 23 can contain a total of four
Groups as an exception.

2.3 Local Partition (LP) Number
The Local Partition (LP) number refers to a logical local processor number, theoretically assigned for each
IMG that consists of four (or less) Port Interface Modules (PIM). Though the local processor does not ac-
tually exist in any of the IMGs, except for IMG0, the system can apply the two-digit LP number to each
IMG (see Figure 2-11) on its data memory program. The LP numbers are used primarily in the...
