Other Band Trunking (OBT)

(Glossary)

HGDefinition.jpg

Other Band Trunking (OBT) encompasses Trunking Systems that operate in the VHF and UHF (specifically UHF1 / UHF R1 or UHF2 / UHF R2) radio frequency bands, as follows:

• VHF (136 to 174 MHz)

• UHF1 (380 to 470 MHz)*

• UHF2 (450 to 520 MHz)

*The end value of UHF1 extends to 472 MHz when the radio / codeplug supports the "Extended UHF Range 1 Capable" Extended Feature. In this case, the Regional Governance is "ACMA".

 

On Trunking Type II systems, the CPS allows only 12.5 kHz operation on OBT channels for radio codeplugs that are subject to the FCC Narrowbanding Mandate. (See also: the Channel Bandwidth field.)
