CHAPTER 2 SYSTEM DESCRIPTION
1. SYSTEM OUTLINE
Remote PIMs can be installed separately in the same building or between the offices via the Public Switching
Telephone Network (PSTN).
The customers in the remote site can use the same service features as in the main site. Remote PIMs are connected
to the main site by T1 (1.5 Mbps) digital interface.
Figure 2-1 shows an outline of the Remote PIM System.
Figure 2-1    Remote PIM System Outline
Note:
The remote PIM contains station and trunk cards. A CPU card is not required in the remote offices.

2. PIM CONFIGURATION
One PIM can be installed respectively as a remote site. A maximum of 3 remote sites can be provided. The number
of remote sites determines the number of PIMs in one system. Table 2-1 shows the available PIM configuration for
the Remote PIM System.

PIM N-UB Port Interface Module for 128/512 port systems/Remote PIM system. 
This PIM can be a Remote PIM or main office PIM.
This PIM provides 19 slots for common control line and trunk cards. This 
PIM houses an AC/DC power supply and optional batteries for short-term 
power interruption.
Three champ connectors for line/trunk (LTC0 to 2) and a connector for 
Power (PWR) are located at the lower front side of the PIM.

For Remote PIM System, BS00 card is required at the main site, even if 
the system is 1-PIM configuration.
PN-CP01 (FP Card) Firmware processor card
For Remote PIM System, CP01 card must be mounted on PIM0 at the 
main site, even if the system is 1-PIM configuration.
RMT PCM-0.3 CA 1 ft. (30 cm) PCM signal cable
This cable is used for connection between DAIA card and BUS interface 
card.
17-TW-0.3 CONN CA-A 1 ft. (30 cm) connection cable between DAIA cards
This cable is required when plural DAIA cards are mounted in a PIM at 
the main site.
48-TW-0.2 CONN CA 1ft. (30 cm) connection cable.
This cable is used for connecting between DAIA card and DAIC card or 
DAIB card and DAIC card. Table 2-2  Required Equipment  (Continued)

Table 2-3 shows the system capacity.
Note 1:1 port is used for the control signaling channel.
Note 2:This number refers to the maximum number of remote offices. The remote office can have only one re-
mote PIM.
Note 3:When the main site consists of 7 or 8 PIMs, a Remote PIM cannot be provided.Table 2-3  System Capacity

6. SYSTEM CONDITIONS
For providing the Remote PIM System to the NEAX2000 IVS, observe the following conditions:
(1) The main site must be the NEAX2000 IVS. The Small Platform System cannot be the main site. The main
site must be a medium platform (320 ports) or a large platform (512 ports). The small platform (72 ports)
cannot be used.
(2) The Remote PIM can be a PIM N-UB, a PIM Q-UA, or a PIM AB-A.
(3) The Remote PIM can be installed at a maximum of 1312 ft. (399 m) distance from the main site. Using line
extension equipment (repeater, MUX etc.), the distance can be extended.
(4) A maximum of 23 lines/trunks can be accommodated in one Remote PIM.
(5) On the remote site, the line/trunk circuit cards can be used as same as the main site, except the CSI card for
wireless system according to UTAM regulation. However, the application circuit cards cannot be used at the
remote site. When providing the ILC card to the remote site, the ICH card must be installed on the main site. 
(6) For the Remote PIM System, the installation procedures for modules, circuit cards and peripheral equipment
are the same as those for the regular NEAX2000 IVS, except the DAIA card and the DAIB card installation
and the BUS cable connection. Refer to the applicable manuals for detailed information.
(7) When the link between the main site and the remote site is lost, the system activates PFT (Power Failure
Transfer) automatically on the remote site, if provided.
(8) The resident system programming cannot be set to the remote site while the main site can be set.
(9) When the LC cards that use an AP card directly (i.e., ILC requires ICH, and 4COTB requires 4RSTC.) If ILC
or COTB are mounted in the Remote PIM, the T1 link between the main and remote sites must be configured
as 64 Kbps with ESF and B8ZS.
(10) In the remote site, if the Remote PIM is a 72-port PIM or a 48-port PIM, when installing a 4-circuit card (LC,
DLC, COT, etc.), assign a phantom DK00 to Level 4 and Level 6 of that LT slot. This assignment will shift
the time slots over enabling the use of additional card slots. (This action is not required if the Remote PIM is
a 64-port PIM.)

7. TIME SLOT ALLOCATION
One time slot of the last 24 time slots provided by the DAIA-DAIB connection is used for the control signaling
channels. Figure 2-3 shows an example of time slot allocation when mounting 8 port cards to the Small Platform
PIM.
