Establishing NMCS
Connections
Network management connections are required so each unit in a network may be
controlled from a central PC-based management application. These connections are
established just as if they were a normal station.
The NMCS host port initiates a connection by defining the host port with
automatic connections to the unit number of the remote TXPORT device. The unit
may be viewed as the name of the unit as opposed to the physical address. The
host port initiates a connect request to the OS which then forwards the request
through the network to the proper destination. When the remote unit receives the
call, it confirms the connection as long as the destination name carried in the user
data field matches its own unit number. The address carried in the user data field is
discarded. The logical pathway is now established and commands may now be sent
by the NMCS application. Figure 4-22 shows the process.
