Parent/Child Deployment Model
Parent/Child Components
The following sections describe the components used in Unified ICM Enterprise (parent) and Unified
CCE System (child) deployments.
CCE System (child) deployments.
The Unified ICM Enterprise (Parent) Data Center
The Unified ICM parent data center location contains the Unified ICM Central Controller. In
, it is shown as a redundant (duplex) pair of Roggers, which are a combination of Call Router
and Logger servers. These servers can be deployed as individual Call Routers and Loggers for a larger
deployment if needed, and they can also be deployed in two different data centers to be geographically
distributed for additional fault tolerance.

, there
is only a redundant (duplex) pair of IVR PGs used to control the Unified CVP across the architecture.
Additional PGs can be inserted at this layer to control TDM or legacy ACDs and IVRs, perhaps to
support a migration to Unified CCE or to support out-source locations that still use the TDM or legacy
ACDs. The Unified ICM parent at this level can also support standard pre-routing with inter-exchange
carriers (IXCs) such as AT&T, Sprint, MCI, and others, thus allowing the Unified ICM to select the best
target for the call while it is still in the carrier network.
