Glossary

pmp-0049 (September 2012)
Term
Definition
RF
Radio frequency. How many times each second a cycle in the antenna occurs,
from positive to negative and back to positive amplitude.
RJ-11
Standard cable that is typically used for telephone line or modem connection.
RJ-45
Standard cable that is typically used for Ethernet connection. This cable may
be wired as straight-through or as crossover. Later 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.
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.
RxBabErr Field
This field displays how many receiver babble errors occurred.
RxOverrun Field
This field displays how many receiver overrun errors occurred on the Ethernet
controller.
Secure Shell
A trademark of SSH Communications Security.
Self-interference
Interference with a module from another module in the same network.
SES/2
Third-from-right LED in the module. In the Access Point Module and
Backhaul timing master, this LED is unused. In the operating mode for a
Subscriber Module or a Backhaul timing slave, this LED flashes on and off to
indicate that the module is not registered. In the aiming mode for a Subscriber
Module or a Backhaul timing slave, this LED is part of a bar graph that
indicates the quality of the RF link.
SFTP
Secure File Transfer Protocol.
Simple Network
Management
Protocol
Standard that is used for communications between a program (agent) in the
network and a network management station (monitor). Defined in RFC 1157.
See http://www.faqs.org/rfcs/rfc1157.html.
SM
Customer premises equipment (CPE) device that extends network or Internet
services by communication with an Access Point Module or an Access Point
cluster.
SM MIB
Management Information Base file that defines objects that are specific to the
Subscriber Module or Backhaul timing slave. See also Management Information
Base.
SNMP
See Simple Network Management Protocol, defined in RFC 1157.
SNMP Trap
Capture of information that informs the network monitor through Simple
Network Management Protocol of a monitored occurrence in the module.
Standard
Operating Margin
See Fade Margin.
