A-13
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.
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.
SDK
PrizmEMS™ Software Development Kit (SDK)—the document that provides server
administrator tasks, GUI developer information for console automation that allows
higher-level systems to launch and appropriately display the Prizm management console.
The SDK also describes the how to define new element types and customize the Details
views.
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.
Session Key
Software key that the SM and Bandwidth and Authentication Manager (BAM)
separately calculate based on that both the authentication key (or the factory-set default
key) and the random number. BAM sends the session key to the AP. Neither the
subscriber nor the network operator can view this key. See also Random Number.
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
skey
Software key that correlates to the random number that the Bandwidth and
Authentication Manager (BAM) server generates and sends in a challenge through the
AP to the SM. The network operator can create and, at some security risk, send this key
over the air to the SM. The SQL database in the BAM server correlates this key to QoS
information about the SM. The format of this key is 32 hexadecimal characters of 0 to 9
and a to f. This key must be unique to the individual SM. Also known as authentication
key.
