The traffic node provides users with access to network services. It operates
under MIDAS control to support circuit management and local resource
management. The traffic node responsibilities can be summarized as:
• Managing local resources under MIDAS control.
• Providing
user traffic interface.
• Accepting
user requests for circuit setup and termination.
The traffic node typically consists of a Comtech EF Data SNM-1000 Node
Control Modem and traffic modems for data and video. Sites requiring a
single data circuit could use the integrated traffic/control modems.
One or more traffic nodes (not co-located with the MIDAS Controller),
together with the RF equipment, antenna and the customer
equipment, are
referred to as a remote site.
