ProSound
When roaming on a wide area (multisite) network, ProSound enables
a radio to select a new site based upon the bit-error-rate of the
"adjacent" sites' control channels. The roaming operation is referred
to as "wide area scan" or "wide area system scan." ProSound ensures
the newly selected site's working channel(s) will be sufficient to
provide quality audio. During wide area scan operations, EDACS
allows up to six (6) adjacent sites to be scanned.
radio system
See EDACS radio system.
RIM
Request Status Monitor Interface Module – The RIM interface
module enables the RSM computer to request information from
radios within the network.
RSM
Request Status Monitor – The RSM is an IBM PC compatible
computer running custom software developed by Ericsson. 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.
secondary interface
The term "secondary interface" refers to the CIA rack. This rack is
considered to be secondary because it is not connected to the primary
TDM and GSC buses within the CEC/IMC.
Secur-It™
The Secur-It / function / hold tones are used for conventional base
station remote control. This tone control sequence is generated by
the CI Boards installed in the CIA rack(s). The tone sequence
consists of two or three parts, the first part is the Secur-It tone,
followed by the function tone, followed by (for transmit functions)
the hold tone. The Secur-It tone level is always +30 dB above the
hold tone and the function tone is always +20 dB above the hold
tone.
simulselect ("soft"/console)
A console operator can simultaneously communicate with two or
more talk groups by selecting the groups for "simulselect"
communication. Simulselect communication uses only a single radio
channel at each active radio system. These "soft" or console
simulselects utilize a special group ID number referred to as a SAID.
