CHAPTER 1 General
7.2 Line Equipment Numbers (LENS)
The Line Equipment Numbers (LENS) are used to specify the location of a circuit (trunk/port) in any of
the PIR universal slots. Refer to the figures in this section, and confirm the LENS format used in the system.
As shown in Figure 1-5, the LENs consists of six digits: two digits for Module Group (MG), one digit for
Unit (U), two digits for Group (G), and one digit for Level (LV).

Figure 1-6 explains the Module Group (MG). In a fully expanded system, the MG number ranges from
00 to 07.
Figure 1-6 Module Group Allocations
7.2.2 Unit
Figure 1-7, that represents a fully expanded system, explains the Unit (U) numbers. The numbers range
from 0 to 3, and each unit represents the PIR Universal Slot 04-12 (U 0/2) or 15-23 (U 1/3).
LENS = XX X XX X
Level (LV) : 0 - 7
Group (G) : 00 - 23
Unit (U) : 0 - 3
Module Group (MG) : 00 - 07
Note
Note:
If an FCH (PA-FCHA) card is used, Line Groups 24-31 can be used as the extended group numbers.
