NDA-24238 CHAPTER 2 Page 9 Revision 3.0 SYSTEM MAINTENANCE OUTLINE 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. Figure 2-6 LENS Format 2.2.1 Module Group Figure 2-7 explains the Module Group (MG). In a fully expanded system, the MG number ranges from 00 to 07. Figure 2-7 Module Group Allocations LENS = XX X XX X Lv (Level) : 0 - 7 G (Group) : 00 - 23 U (Unit) : 0 - 3 MG (Module Group) : 00 - 07Note Note: If an FCH (PA-FCHA) card is used, line groups 24-31 can be used as the extended group numbers.

NDA-24238 CHAPTER 2 Page 13 Revision 3.0 SYSTEM MAINTENANCE OUTLINE 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 following cases: Display of system messages Assignment of line load control data (ALLC command) Backup for Call Forwarding/Speed Calling data (MEM_HDD command), etc. Figure 2-11 LP Number Allocations FRONT VIEW PIM3 PIM2 PIM1 PIM0PIM3 PIM2 PIM1 PIM0PIM3 PIM2 PIM1 PIM0PIM3 PIM2 PIM1 PIM0 TOPU IMG0 FANU BASEULPM TOPU IMG2 FANU BASEU DUMMY TOPU IMG3 FANU BASEU DUMMY TOPU IMG1 FANU BASEUTSWM LP No. = 00 LP No. = 02 LP No. = 04 LP No. = 06 The Local Partition No. (two digits, even number) is assigned on each IMG.
