ProSound

When roaming on a wide area (multisite) network, ProSound enables

aradio 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.
