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.

2.2.1 Module Group
Figure 2-13 explains the Module Group (MG). In a fully expanded system, the MG number ranges
from 00 to 07 in each local node.

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 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.

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 nodes outside the IPX-U system
For more details, refer to Figure 2-18.
Note 1:Within the IPX-U system, the NCN can be designated only from the Local Nodes (LN0-LN3). The ISW
cannot be assigned as the NCN.
Note 2:On a Fusion network, assign only one NCN. Multiple nodes cannot be assigned as the NCN.
Because the Fusion link can be established either independently within the system (IPX-U) or jointly with
other outside IPX series, the assignment of NCN can differ, depending on the network configuration. 
						

							CHAPTER 2 NDA-24307
Pag e 2 2

SYSTEM MAINTENANCE OUTLINE
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.
Figure 2-18   Example of NCN Assignment (1/3) Note 1:
The network-level data (NDM data) can be assigned only at the NCN. However, other node-level
data (LDM data) must also be assigned at each node (including ISW), depending on the
requirements. For more details, refer to the “Installation Manual (IPX-U Type)” or the “Fusion
Network System Manual.” 
Note 2:When the system is operated, the function to be performed by the ISW is only to provide the PCM
time slot switching between the Local Nodes. However, an FPC (Fusion Point Code) must be as-
signed also for the ISW together with other Local nodes, by using the ASYDL command.
