TERM DEFINITION
SNMP See Simple Network Management Protocol.
StarGate In EDACS trunking, links up to eight EDACS wide-area multisite networks to
create a single, seamless network.
StarGate Controller A StarGate Controller is an IMC switch specifically configured for
distributed multisite operation. It is the central point or "hub" for all distributed
multisite communications.
SubSite Number This is the EDACS SubSite Number which uniquely identifies the SubSite
device on a particular Node. A channel is a subsite device.
super user The root user who has special privileges. Same as the System Administrator.
Switching Center Collection of node level devices physically connected to the IMC. These
devices include the PI, BCU, CAL, EDG, and Consoles.
System Manager The System Manager is a DEC multitasking computer which performs
features such as monitoring system operation, generating management reports,
individual unit enable/disable and dynamic regrouping.
T1/E1 Digital landline and microwave transmission standards used in the United

TDM Time Domain Multiplexing. Technique used to multiplex multiple signals
onto a single hardware transmission channel (bus) by allowing each signal to
use the channel for a short time before going on to the next one.
TDM bus Time Division Multiplexed bus
−
The TDM bus in the CEC/IMC switch is a
digitally multiplexed bus system used to transfer audio/mobile data/Aegis data
throughout the CEC/IMC switch. Each signal coming into the CEC/IMC
switch is assigned a TDM time slot and receiving devices extract the digitized
signals from the appropriate time slot.
Technician (or Tech or
EDACS technician) Customer personnel whose main responsibility is to install, maintain, and
troubleshoot individual EDACS platforms, such as GETCs, Site Controllers,
EDGs, and IMCs. Technicians require software interfaces that run on common
laptop/desktop personal computers to assist in hands-on setup of a particular
platform.
Telnet The TCP/IP protocol that enables a terminal attached to one host to log into
other hosts and interact with their applications. It is the Standard internet
protocol for terminal emulation.
TFTP Trivial File Transfer Protocol. A basic TCP/IP protocol used to upload or
