The MIDAS software uses the following windows to set up the structure, or
hierarchy, of the various network elements, and as a basis for relational
database records: Sites, Nodes, and Channels. Because of this progressive
structure, it is required that these elements be set up in this sequence, due to the
referential integrity rules of the database; i.e., a Node cannot exist until a Site is
created, etc.
Sites
this pair of windows allows the operator to set up the network Sites. The Sites must be
configured for contact information, control channel power levels, etc. Each Site will have one
or more Nodes associated with it. The lower portion of the Site window also displays the list of
associated nodes within the Site, and provides access to the Node window, which allows the
operator to edit the channels within each node.
Nodes
this pair of windows is accessed via the Edit button (Node window), which allows the operator
to edit an existing Node within a Site, or the Add button (Enter Node),which allows the
operator to Add a Node to a Site, on the lower portion of the Site window. Each Node can
have up to 30 channels assigned to it.
Channels this pair of windows is accessed via the Edit button (Channel Details), or the Add button (Enter
New Channel) on the lower portion of the Node window.

The operator will set up the Sites first, which will be used in the network. This
window allows the operator to create and configure the Sites, of the following
descriptions:
• NMS Site – the NMS Site hosts the MIDAS Network Management
System, which is responsible for managing the entire network, as well as
the necessary RF equipment. The NMS may also have one or more traffic-
carrying nodes sharing the equipment with the NMS. If a node exists at the
NMS location, it will still communicate with the NMS over the satellite.
An NMS Site record is required in the MIDAS database. The system will
not function without an NMS Site record, and it will not allow the NMS
Site to be deleted. However, the system does permit changes to the NMS
Site record.
• Remote Site – a Remote Site consists of one or more traffic-carrying nodes
with common RF equipment. The site is configured to specific customer
requirements. In a multi-node Remote Site, the co-located nodes still
communicate with each other over the satellite.
