MIDAS 4.2 Basic Configuration, Rev. 1
2–40 Setup and Operation
N N o o d d e e s s
Once the operator has established a Site, one or more Nodes can be created and
configured. A Node in the MIDAS system provides the traffic channel
characteristics for the required services, and operates with the Controller
Server to support satellite network circuit management and local resource
management. The node responsibilities can be summarized as:
• Managing local resources in cooperation with the Controller Server
• Allowing
the local user to request circuits
• Providing one or more (up to 30) traffic channels for user traffic interface
The node equipment consists of a Node Control modem, equipped with a DAC
card, and one or more traffic modems.
The Node Control modem functions as the local controller for the node,
maintains communication with the Controller Server on the inbound and
outbound control channels, and controls the internal or external traffic
modem(s).
One or more nodes (not co-located with the Controller Server) along with the
RF equipment and the customer
equipment is referred to as a remote site.
The transmit burst power entry is used to allocate power from the site’s HPA
as part of power management. This is to ensure that the amplifier is not
overdriven during burst transmission. It does not actually set the burst power at
the node. That must be done manually at the node, and must match the value
entered in the site configuration.
Click the Add button on the lower portion of the Site window to access the Enter Node
window, which allows the operator to Add a Node to a Site.
The operator must enter a Node Number into the field on this window, which
must correspond to the Node address in the remote control modem, in
accordance with their particular numbering scheme.
