Cisco Personal Assistant 1.4 Installation and Administration Guide
OL-4590-03
Chapter 1      Planning for Personal Assistant
Understanding the Personal Assistant Server and Speech-Recognition Server
For specific items, such as user names in the corporate directory, the grammar is generated and 
automatically compiled during the system refresh (see the 
). As new users are added to the directory, their names are automatically recognized after the 
refresh.
Personal Assistant Server
The Personal Assistant server manages the interaction between the user and Personal Assistant, 
processes call routing and dial rules, and manages the overall configuration of the Personal Assistant 
system.
You must install the Personal Assistant server during installation, and you manage its functions and 
processes from the administrator web-based interface (see the 
 for information about accessing the 
interface).
You can have more than one Personal Assistant server configured. In fact, you should do this if you want 
to provide failover protection (see the 
 for details). 
License and Resource Managers
The license and resource managers are subcomponents of the Personal Assistant server; they are 
installed with it. However, they actually work in conjunction with the speech-recognition and 
Personal Assistant servers. Although the license manager and resource managers provide different 
services, they are closely linked, in that every system that functions as a license manager also functions 
as a resource manager.
License Manager
The license manager maintains the license for the speech-recognition software. The speech-recognition 
servers work only if there is at least one active license manager with a valid license. Although every 
Personal Assistant server includes a license manager, not every Personal Assistant server needs an active 
license manager.
You only need one license manager within a single Personal Assistant server cluster, although Cisco 
recommends that you define two license managers for redundancy.
Resource Manager
The resource manager manages the interaction between the Personal Assistant server cluster and the 
speech-recognition servers in the speech-recognition server cluster. Although every Personal Assistant 
server includes a resource manager, only one resource manager is used as the active connection between 
the Personal Assistant server cluster and the speech-recognition server cluster. Personal Assistant 
automatically chooses the resource manager to be used, and if that manager becomes disabled, another 
resource manager takes over.
Once a resource manager establishes a connection between a Personal Assistant server and an available 
speech-recognition server for a particular call, the Personal Assistant server and speech-recognition 
server interact directly for the duration of that call. The resource manager is not a permanent 
communication link between the servers.
The resource manager does not manage communication between Personal Assistant servers; 
Personal Assistant servers communicate directly.
