Introduction

Figure D-1. High-Level Thin Client Architecture
As shown above, the Directory application and its administration are co-resident with an HTTP
server. Administration screens allow all Directory application parameters (such as the directory
database server’s IP address or DNS name, allowable search fields, results returned, etc.) to be
set via a PC browser (web browser may be co-resident on Directory Application Server).
When a 4620 IP Telephone user initiates a directory search, the user’s browser sends the search
criteria to the Directory application. The Directory application sends a query (based on
administered parameters) to the directory database (usually located on a separate server). The
directory database server then returns search results to the Directory application, which formats
them in the appropriate markup language and sends the results back to the end user. The user
then has several options regarding the search results.
