Reflection
Change of direction and reduction of amplitude of a signal that
encounters an object larger than the wavelength. Reflection may
cause an additional copy of the wavelength to arrive at after the
original, unobstructed wavelength arrives. This causes partial
cancellation of the signal and may render the link unacceptable.
However, in some instances where the direct signal cannot be
received, the reflected copy may be received and render an otherwise
unacceptable link acceptable.
RegistrationsMIB
Management Information Base file that defines registrations for global
items such as product identities and product components. See also
Management Information Base.
replm
A command that sets up the database replication process on a
Bandwidth and Authentication Manager (BAM) master server, uses
SFTP to copy both the database and the repl-s script to a BAM
slave server, and remotely executes the repl-s script on the BAM
slave server. See Master, Slave, repl-s, Secure Shell, and SFTP.
repls
A command that sets up the database replication process on a
Bandwidth and Authentication Manager (BAM) slave server. See
Master, Slave, and repl-m.
RES
Result. A field in the data that the cmd show esn command
generates from the SQL database in the Bandwidth and Authentication
Manager (BAM) server.
RetransLimitExpField
This field displays how many times the retransmit limit has expired.
RF
Radio frequency. How many times each second a cycle in the antenna
occurs, from positive to negative and back to positive amplitude.
RJ11
Standard cable that is typically used for telephone line or modem
connection.
RJ45
Standard cable that is typically used for Ethernet connection. This
cable may be wired as straight-through or as crossover. Later Cyclone
modules auto-sense whether the cable is straight-through or
crossover.
Router
Network element that uses the logical (IP) address of another to pass
data to only the intended recipient. Compare to Switch and Bridge.
RPM
Red Hat
®
Package Manager.
rpm
A command that the Linux
®
operating system accepts to identify the
version of Linux
®
software that operates on the Bandwidth and
Authentication Manager (BAM) server.
RSSI
Radio Signal Strength Indicator. A relative measure of the strength of
a received signal. An acceptable link displays an RSSI value of greater
than 700.
