System Outline
SYSTEM OUTLINE
Remote PIMs can be installed separately at the distance in one 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) / E1 (2 Mbps) digital interface.

PN-CP15 FP Firmware Processor Card
Provides Line/Trunk interface, Memory (RAM 768 KB), and 
inter-module BUS interface. BUS interface functions as a 
driver/receiver of various signals, adjusts gate delay timing 
and cable delay timing, monitors I/O BUS and PCM BUS. 
When the system consists of three or more PIMs, one each of 
this card is mounted respectively in PIM0, PIM2, PIM4, and 
PIM6.
For Remote PIM System, the FP card must be mounted on 
PIM0 at the Main Site, even if the system is 1-PIM/2-PIM 
configuration.

CHAPTER 1  GENERAL INFORMATION
System Conditions
SYSTEM CONDITIONS
 Only one PIM configuration is available at the Remote Site.
 Remote PIM can be installed at a maximum of 400 m (1312 ft.) distance from the Main Site.
Using the Optical Interface card (PN-M10) or line extension equipment (Repeater, MUX, 
etc.), the distance can be extended.
 At the Remote Site, the line/trunk cards can be used as same as the Main Site. 
For North America, the line/trunk cards, except the CSI card for wireless system according 
to UTAM regulation, can be used.
 The application processor cards cannot be used at the Remote Site. When you provide the 
ILC or CSI card to the Remote Site, the ICH or CSH card must be installed on the Main Site. 
 For Remote PIM System, the installation procedures for modules, circuit cards, and periph-
eral equipment are the same as those for the regular system, except the DAI cards instal-
lation and the BUS cable connection.
Refer to the Installation Procedure Manual for detailed information.
 When the link between the Main Site and Remote Site has been lost due to power failure or 
PCM Frame Loss, the system activates the Power Failure Transfer (PFT) automatically on 
the Remote Site, if provided.
 The Resident System Programming cannot be set to the Remote Site while the Main Site 
can be set.
 If ILC or COTB card is mounted in Remote PIM, the T1 link between main and Remote Sites 
must be configured as 64 Kbps with ESF and B8ZS.
