System Overview
System overview explains what type of systems and modes available in the radio.
4.1
Capacity Max
Capacity Max is MOTOTRBO control channel based trunked radio system.
MOTOTRBO digital radio products are marketed by Motorola Solutions primarily to business and
industrial users. MOTOTRBO uses the European Telecommunications Standards Institute (ETSI)
Digital Mobile Radio (DMR) standard, that is, two-slot Time Division Multiple Access (TDMA), to pack
simultaneous voice or data in a 12.5 kHz channel (6.25 kHz equivalent).
4.2
Conventional Analog and Digital Modes
Each channel in your radio can be configured as a conventional analog or conventional digital channel.
Certain features are unavailable when switching from digital to analog mode, whereas some are
available in both.
There are minor differences on how each feature works but they do not affect the performance of your
radio.
4.3
IP Site Connect
This feature allows your radio to extend conventional communication beyond the reach of a single site
by connecting to different available sites by using an Internet Protocol (IP) network.
When the radio moves out of range from one site and into the range of another, the radio connects
to the repeater of the new site to send or receive calls or data transmissions. This is done either
automatically or manually depending on your settings.
In an automatic site search, the radio scans through all available sites when the signal from the current
site is weak or when the radio is unable to detect any signal from the current site. The radio then locks
on to the repeater with the strongest Received Signal Strength Indicator (RSSI) value.
In a manual site search, the radio searches for the next site in the roam list that is currently in range
but which may not have the strongest signal and locks on to the repeater.
NOTE: Each channel can only have either Scan or Roam enabled, not both at the same time.
Channels with this feature enabled can be added to a particular roam list. The radio searches the
channels in the roam list during the automatic roam operation to locate the best site. A roam list
supports a maximum of 16 channels, including the selected channel.
NOTE: You cannot manually add or delete an entry in the roam list. Contact your dealer for
more information.
