AS8100 SITESPAN SYSTEM OVERVIEW
AS8100 Sitespan is a distributed control system for managing the AS4000 Fixed
Assignment and Demand Assignment products.
AS8100 Sitespan allows equipment at several sites to be configured and monitored from
a single remote station and allows several stations to connect to a single site
simultaneously.
AS8100 Sitespan has the following features:
• An intuitive graphical user interface (GUI) to access all products and services.
• Real time display, propagation and logging of equipment alarms throughout
the managed site network.
• Easy site to site network navigation.
• logging of all operations performed on managed equipment as well as
equipment states.
• support for multiple users to simultaneously monitor sites.
• support for multiple sites to be monitored simultaneously.
• access to sites from either dialup modem links or network connections.
• multi-level Undo of all operations in each user session.
AS8100 Sitespan has two distinct components:
a) A Server that is directly connected and associated with the equipment racks.
b) An Equipment View that supplies the user interface.
These two components can run either on the same machine or on separate
machines
The AS8100 Sitespan Server is the AS8100 Sitespan component responsible for
monitoring and controlling the telecommunications equipment connected to it.
The Server communicates with the equipment shelves in their respective native control
languages to issue commands or collect status. The Server is instructed to carry out these
management duties by commands from connected Equipment Views.
The Server's job is to translate Sitespan commands received from users at Equipment
View terminals into command sequences in the native languages of the connected
equipment. These sequences are issued to the equipment shelves and responses from the
shelves are translated into Sitespan status messages before being sent to all connected
Equipment Views.
Once a Server has been instructed to configure its connected equipment, it will manage
the equipment regardless of whether any Equipment Views continue to be connected. All
operations and alarms are written to a transaction log file located on the Server machine
maintaining a complete record of status.
The Equipment View application is the user interface through which equipment at all
sites on an AS8100 Sitespan network can be controlled or monitored. Several Equipment
Views can be connected to a single Server, allowing geographically disparate groups of
users to manage equipment at a particular site. Also, each Equipment View can connect
to several Servers, allowing individual users to manage equipment at a number of
different sites.
If two or more Equipment Views are connected to the same site Server then the
consequences of changes made by one user can be seen by all others. For example, if a
user creates a set of subscribers for a shelf, the new subscriber records will appear in the
