Appendix C Glossary
Asynchronous: a communications system in which data
transmission may start at any time and is indicated by
a start bit, e.g. RS-232.
Bandwidth: the difference between the highest and
lowest frequencies of a transmission channel (the
width of its allocated band of frequencies). The term
is often used to mean data rate or capacity - the
amount of data that is, or can be, sent through a
given communications circuit per second.
Network Control Unit (NCU): a radio that exerts control
of the system through supervisory control and system
timing. This radio also stores the system
configuration, and relays those settings to the other
radios in a system.
Channel: a frequency band selection. The SR-7100 System
offers the choice of up to 21 Channels within the 2.4
GHz spectrum. May also be used to describe a virtual
path between two network ports.
Channel ID (or Service ID): a number used to uniquely
identify a specific data exchange.
Data Throughput: the data pass-through capability for a
Service in a particular direction. For example, a point-
to-point Service may be configured to have a Data
Throughput of 19.2 Kbps in one direction and a Data
Throughput of 9.6 Kbps in the other direction.
DHCP: Short for Dynamic Host Configuration Protocol, a
protocol for assigning dynamic IP addresses to
devices on a network. With dynamic addressing, a
device can have a different IP address every time it
connects to the network. In some systems, the
device's IP address can even change while it is still
connected. DHCP also supports a mix of static and
dynamic IP addresses.
