Card Slot Arrangement

4.30 The circuit card slot on the far right (8th slot) of the basic equipment chassis is reserved

for the CPU card or CPC. Other than that, any station, trunk, or optional resource card may be

placed in any of the remaining seven slots. If a second chassis is attached, the CPU card or

CPC in the first (master) chassis also controls the second chassis (e.g., slot number 16 remains

4.31 For a non-ATM system, if a third chassis is attached, it must be equipped with a "slave-

version" CPU020-X/PCM-F card in slot number 24. If a fourth chassis is attached, the

CPU020-X/PCM-F card in the third chassis also controls the fourth chassis (e.g., slot number

32 remains empty). As of version 8.0, tri- and quad-chassis systems require the CP Server; so,

the CPU in slot number 8 must have an EAC so that it can connect to a CP Server.

4.32 ATM-based systems do not have a master-slave relationship, which means that any

chassis pair can go offline without affecting the rest of the system. There are several advan-

tages to this:

4.33 Because the ATM system chassis are no longer dependent on each other, each chassis

pair is identified by the PCMA number assigned when configuring the chassis (see

For example, if a dual-chassis system houses PCMA #1, that system is referred to as PCMA

without affecting the other chassis in the system. Any calls associated with or using the

resources of a chassis that goes offline, however, are dropped.

4.34 Information on the type of card installed in each card slot must be entered through

Database (DB) Programming.

MANUAL VERSION 11.0 – May 2008

When using the CP Server, the "slave" CPU is used just as it would be with the other

Should a CPU or other piece of hardware fail, the entire system does not fail, just that

equipment chassis.

Hardware replacements can be handled on a per-chassis basis without having to power

off the entire system.

The system can be designed to spread critical business operations over several chassis

to protect the system should any chassis go offline, whether scheduled or not. After the

chassis comes back online, it powers up and begins functioning with the rest of the sys-

Any equipment chassis in an ATM system should be able to go offline and back online
