The AW provides administrative and maintenance software for the DRM. It is
equipped with a mirrored disk for reliable storage of software applications and data.
The AW contains an AM emulator and a simulated CM2 to emulate what is found on
the 5ESS switch. The AW oversees many of the global administrative operations
required in the DRM. These operations include storing Automatic Message Accounting
(AMA), monitoring system configurations, and providing backup storage for
application programs. The AW provides local human-machine interface with the DRM.
The AW is not involved in call processing. Therefore, there is no call processing impact
if the AW were to encounter a fault during operation.
In case of an AW outage, the switching module is capable of storing 72 hours of AMA
data before requiring download to the AW for storage on the hard disk. A switching
module circular AMA data buffer protects AMA data by ensuring that certain pointers
in the AMA storage area are not updated until the AMA data can be retrieved once the
AW is restored.
The following interface connectors, which are depicted in Figures 2-5, 2-6 and 2-7
allow peripheral devices and terminals to be interfaced to the AW. Any peripheral
interface connectors not listed below are unused by the DRM application. See Section
