R
radio channel
Represents an assigned band of frequencies sufficient for radio communication.
The bandwidth of a radio channel depends upon the type of transmission and its
frequency tolerance.
radio equipment
Any equipment or interconnected system or subsystem of equipment (both
transmission and reception) that is used to communicate over a distance by
modulating and radiating electromagnetic waves in space without artificial
guide. This equipment does not include microwave, satellite, or cellular
telephone equipment.
receive indicator
The indicator on the PMC that blinks green when traffic is being received.
remote connection
Cisco IPICS uses this type of connection to provide SIP-based trunking into the
RMS component, which is directly tuned into the multicast channel.
RF
radio frequency. Any frequency within the electromagnetic spectrum that is
normally associated with radio wave propagation. RF generally refers to
wireless communications with frequencies below 300 GHz.
RF repeater
An analog device that amplifies an input signal regardless of its nature (analog
or digital). Also, a digital device that amplifies, reshapes, retimes, or performs a
combination of any of these functions on a digital input signal for
retransmission.
RMS
router media service. Component that enables the Cisco IPICS PMC to remotely
attach to a VTG. It also provides support for remotely attaching (combining) two
or more VTGs through its loopback functionality. The RMS mixes multicast
channels in support of VTGs and it mixes remote PMC SIP-based (unicast)
connections to a multicast channel or VTG. The RMS can be installed as a
stand-alone component (RMS router) or as an additional feature that is installed
in the LMR gateway.
RTP
Real-Time Transport Procotol. Commonly used with IP networks to provide
end-to-end network transport functions for applications transmitting real-time
data, such as audio, video, or simulation data, over multicast or unicast network
services.
