The SCP (if required), subscriber database, and Web server can physically
reside on the CACS server. In large systems, however, these components may
be distributed among multiple servers in order to distribute the processing
load.

Bridges
When a caller dials a ReadiVoice-PSTN subscriber's access phone number on
a typical routed ReadiVoice system:
The originating central office switch recognizes the number as requiring
1
carrier common channel signaling network handling.
The carrier switch sends a query through the carrier common channel
2
signaling network to the ReadiVoice CACS, which allocates bridge
resources to that subscriber according to his or her subscriber account
settings.
The CACS returns a routing solution through the carrier common
3
channel signaling network to the originating carrier switch. It also
notifies the bridge of the upcoming call and the associated account profile
and features.
