SYSTEM ARCHITECTURE
Designed to provide alarm and configuration management for Airspan’s product range,
Sitespan is capable of meeting a wide range of customer’s requirements, operating
either on a single, stand-alone PC or within a multi-user client-server network.
Microsoft Windows NT provides the operating system, which permits this scalability.
Sitespan is built from two core applications: Client and Server. The Server provides
communication to and from the managed equipment maintaining an up-to-date object
model whilst the Client provides the user interface, communicating only with the
Server application. Both applications can run concurrently on a single Pentium PC
providing for smaller/single user installations.
The system permits multiple Clients to connect to multiple Servers either by direct
network connections or by dial up connections. This enables Sitespan to span a large
number of managed elements.
Communications between the Client and Server applications have been optimised in
order to enable dial-up connections at speeds as low as 9.6Kbps whilst maintaining as
near to real-time operation as possible.

Connection for each shelf. A single computer fitted with communication port
expansion cards may support multiple shelf connections. This is shown in
