Table 3.2.8.5-1 P25 Trunk Band Plan Defaults
Bandwidth (Band Plan Table submenu)
Select 6.25 kHz or 12.5 kHz using a horizontal submenu.
Base Frequency (Band Plan Table submenu)
Set the radio’s receive frequency for channel number 0 in MHz using the ▲▼ (Up/Down), and ◄►
(Left/Right) keys, numeric keypad, and spin knob.
Channel Spacing (Band Plan Table submenu)
Set the frequency distance between adjacent channels in 0.125 kHz increments using the ▲▼ (Up/Down),
and ◄► (Left/Right) keys, numeric keypad, and spin knob. This is used to compute the channel frequency
from the channel number (or vice versa).
Transmit Offset (Band Plan Table submenu)
Set the frequency offset from the radio receive frequency to the radio transmit frequency in MHz using
the ▲▼ (Up/Down), and ◄► (Left/Right) keys, numeric keypad, and spin knob. Conversely, the setting
defines the offset from the base station transmit frequency to the base station receive frequency.
Radio TX frequency = Radio RX fre Transmit Offset
Base Station TX frequency = Base Station RX frequency - Transmit Offset
Channel Identifier (Band Plan Table submenu)
Set the channel plan number from 1 to 16 using the ▲▼ (Up/Down), and ◄► (Left/Right) keys, numeric
keypad, and spin knob. This value is used as part of the channel definition in the voice channel grant
message.
Identifier Update (P25 Trunk submenu)
Set to ON or OFF. Activate the Identifier Update that provides data to inform the subscriber unit of the
parameters associated with a specific channel. When set to ON, the IDEN_UP TSBK appropriate for the
specified Band Plan (see Band Plan Table submenu) is transmitted on the control channel. The 700 MHz
and 800 MHz bands use the 800/700 MHz format IDEN_UP TSBK with fields set as specified in the Band
Plan Table; the UHF/VHF bands use the UHF/VHF MHz format IDEN_UP_VU TSBK. When OFF, no
IDEN_UP TSBK is transmitted on the control channel.
