User Guide

The Router serves as a real-time server by immediately forwarding this data directly to the
Administrative Workstations so that it is available to appear in reports. The Router also writes
records to the Central Database on the Logger.
•
Logger and Central Database
The Logger receives data from the Router (such as detail messages about calls and summary
messages that have been computed by the Peripheral Gateways) and serves as the interface
between the Router and the SQL Server database manager.
The following data-management processes occur at the Logger:
–
Data is written first to temporary tables.
–
Data is then written to actual tables on the Central Database.
–
Historical records on the Central Database are replicated to the Historical Data Servers
(page 16) on one or more distributor Admin Workstations.
The Central Database serves as a buffer where data is committed to quickly support the
performance of the Router. The Central Database stores the following data:
- Configuration data, as entered and changed on the Admin Workstation
- Routing scripts, as entered and changed on the Admin Workstation
- Summary historical data (page 25) passed from the Router
- Termination and Router call detail data (page 26)
The Central Controller Database stores no real-time data.
See also Cisco Unified ICM Data Environment (page 23).
Peripherals and Peripheral Gateways
The Central Controller obtains the routing and reporting data that it processes by communicating
with each network peripheral.
A peripheral is a device (such as an ACD, a PBX, or an IVR) that receives calls that have been
routed by Unified ICM software. A peripheral can also distribute calls or non-voice media
contacts.
In the illustration below, the peripheral is an ACD.
The Central Controller communicates with each peripheral through a monitoring node called
the Peripheral Gateway (PG).
