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
system.
As shown in Figure 2-12, 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
Details on Unit (U) numbers are shown in Figure 2-14. 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 2-15. 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.

Group number, which ranges from 00 to 31.

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
actually exist in any of the IMGs, except for IMG0, the system can apply the two-digit LP number to each
IMG (see Figure 2-17) on its data memory program. The LP numbers are used primarily in the...

2.4 Assignment of Network Control Node (NCN)
The IPX-U system can be in service by dialing a Telephone Number assigned for each station at a Network
Control Node (NCN). Because these network-level data (NDM data) can be assigned via the MAT
dedicated to the NCN only, designate any of the following nodes as this network data manager (NCN):
One of the Local Nodes (LN), excepting for the ISW, within the IPX-U system
One of the belonging Fusion...

Pattern 1 When the system has a Fusion link independently of other systems
If the system has a Fusion link only within the system (i.e. no Fusion link is established with other IPX
series), an NCN must be assigned from any of the existing Local Nodes, excepting the ISW. In this
example, LN0 is assigned as the NCN.

The network-level data (NDM data) can be assigned only at the NCN....
