Ericsson LBI-39169 manual Rsm, Scat

	GLOSSARY	LBI-39169
TERM		DEFINITION
	enables the RSM computer to request status information from radios within the
	network.
Router	A system used to connect separate LANs and WANs into an internet, and to
	route traffic between the networks. In the Network Manager system, a router is
	needed to go from Ethernet to T1 physical media. OSI Network, Data Link,
	and Physical Layers only.

RS-232

RSM

A type of serial interface typically used for terminals, modems, and printers.

Request Status Monitor − The RSM is an IBM PC compatible computer running custom software developed by Ericsson GE. It allows the system administrator and/or the dispatchers to view status of EDACS units within the CEC/IMC network. Status information is typically initiated (transmitted) by the radio operator to identify the current condition (in route, at scene, etc.) of the unit.

SCAT	Single-Channel Autonomous Trunking. In EDACS, SCAT is a trunked system
	consisting of a single failsoft repeater and a downlink GETC. Operationally, it
	functions as a control channel or a working channel, depending on the trunked
	service required. In its idle state, SCAT operates as a control channel. When a
	channel request is made, SCAT assigns the call to itself and converts to a
	working channel. EDACS address hierarchy is maintained as are many
	trunking features.
Shell	An HP-UX command interpreter (CSHELL, KORN, etc.), providing a working
	environment interface for the user. When user logs in, the Session Manager
	starts HP VUE applications that were running during a previous session.
Simple Network Management	The Simple Network Management Protocol (SNMP) is a protocol that enables
Protocol	a management station to configure, monitor, and receive trap (alarm) messages
	from a Network Element. It also provides additional administrative structure,
	authentication, and privacy.
Simulcast	Simultaneous Broadcast by two or more transmitters located at different sites
	operating on the same RF frequency.
site	This term normally refers to EDACS radio equipment at a single specific
	location.
Site Controller	A computer running Ericsson-developed application software that controls the
	moment-to-moment trunking process, plus such features as call validation, unit
	enable/disable, dynamic regrouping, and queuing management. The Site
	Controller communicates with the System Manager over an appropriate link.
Site Icon	The Site icon consists of physical devices located in one geographic location
	such as the Site Controller, ELI, ACU, PMU, TU, and Channels.
Site Number	This is the EDACS Site Number which uniquely identifies the Site on a
	particular Node.
SM	See System Manager.
