Master vs. Station Decide which NCL1135 is the master. In the point-to-point
configurations, it does not matter which NCL1135 is master,
just remember that the master provides the access control to
the station. In the case of point-to-multipoint, the master must
have a line of sight to each station, but each station may not
have a radio communication path to other stations.
Open Shortest Path First A routing protocol for autonomous IP networks based on the
Shortest Path First (SPF) algorithm, where link-state
advertisements (LSAs) are sent to all other routers within the
same network to determine the shortest path to the desired
node.
Radio Channel A 22 MHz wide RF channel with a center frequency specified
in Appendix C. In any given network, all NCL1135s must
operate on the same radio channel to communicate.
Radio Type This parameter specifies the role of the NCL1135 in the radio
network. Each NCL1135 is classified as either a master or a
station.
Router A device that connects and passes packets between two or
more network segments. A router filters or forwards an
incoming packet based on the IP address of the packet.
Routers use static routes which take precedence over routes
chosen by all dynamic routing protocols. See also Bridge.
Routing Information
Protocol
A routing protocol for IP networks based on the distance-
vector algorithm, where all or a portion of the routing table is
sent to all other neighbouring devices along with each
message.
Static Route A route that is explicitly configured and entered in the routing
table. Static routes take precedence over routes chosen by
dynamic routing protocols.
Station An NCL1135 defined as a station synchronizes with an
NCL1135 master that has the same station and master ID
setting.
System Name A name that allows a user to identify a particular NCL1135.
Once the Name is assigned, the system name appears as the
prompt.
System Password A set of characters that prevents unauthorized access to
console commands. The same password applies when
accessing the console from the RS-232 port, from the network
using Telnet, or when connecting to the FTP server.
Unit ID In the case of a station, unit ID provides the wireless address
at the station. In the case of a Master, a list of unit IDs forms
the access list of stations allowed to communicate with the
Master. Any station not on the list will be disabled whenever
the station attempts to access the Master.
