1. General Function
The PH-GT09 (GT) circuit card provides both the TSW I/O Local bus and the MISC bus interface. The
CPR controls TSW, PLO, DLKC, and MISC via the ISAGT and GT.

SN1455 CPRAQ-A/SN1531 CPRAS-A
CPU Board
1. General Function
The CPR consists of the following components.
(a) CPU BOARD: Contains the Main Processor Unit (MPU), ROM, and 128 Mbyte of Random Access 
Memory (RAM). This board may also contain the ISAGT (PZ-GT13/PZ-GT20) on 
its Industrial Standard Architecture (ISA) bus, and LANI (PZ-PC19) on the 
Peripheral Component Interconnect (PCI).
(b) DSP: Contains the CPR switches...

2. Mounting Location/Condition
The CPR is composed of the CPU BOARD, DSP, FDD/HDD, and PWR and is located in the Local
Processor Module (LPM) as shown in Figure 2-10. Since the CPR provides the Industrial Standard
Architecture (ISA) bus and Peripheral Component Interconnect (PCI) bus, the ISAGT and LANI cards are
located in those busses respectively.
