Technical Information:
The CPU200 module consists of two different cards. The card at the bottom has the address
and data buses that carry the required signals to the main rack of the exchange, whereas the
upper one contains the entire memory elements and the Power PC (PPC) 850 processor
circuits. The PPC is a RISC based processor of 80 MIPS processing power.
The CPU200 Module is plugged into the corresponding 64-pin connector on the BPL200-
MAIN backplane and it is fixed to the upper and lower front sections of the metal rack
through the fixing latches that are on the front card cover.
CPU200 contains memory elements such as 32 MB FLASH ROM, 256 MB DRAM and
EEPROM, as well as the ICP (Intra-rack Communication Protocol). In addition to that,
CPU200 is responsible for generation of system clock pulses.
CPU200 generates address and data signals, which are required for the UTIL200 and EX200
Modules. It transmits those signals to BPL200-MAIN over a 64-pin connector, and to the
BPL200-AUX backplane over the two 34-pin connectors that provide the BPL200-MAIN -
BPL200-AUX connection, and to the second cabinet over a 34-pin connector that is
employed for that transmission when required.
Data signals which are essential to the entire accessories are generated on CPU200 and
then they are transmitted to DS200 CPUKON over DS200 CPU-FC.
Operational Information:
A LED is situated on the front panel of CPU200. This LED continuously blinks during normal
operation. On the other hand, it remains on during a reset or parameter transfer. By this
way, the status of the system can be monitored through this LED.
The CPU200 card has two Ethernet connectors. One is for a PC connection for maintenance,
programming, etc and for IP extensions. The other one is for IP trunks.

CPU200 MUST NOT BE REMOVED WHILE THE SYSTEM IS OPERATING.
Dimensions of CPU200 are 20 cm. x 22.5 cm. and it weighs 0.3 kg.
