The IC-FR3000/IC-FR4000 series has D-SUB 25
pin/modular interfaces for external controllers such as
PassPort® and MPT1327. MPT1327 is a signalling
standard for trunked private land mobile radio systems.
It defines the protocol rules for communication between
a trunking system controller (TSC) and users' radio units.
This is a basic plan to upgrade the repeater site to a
trunking system. This plan is an example of a single
trunking repeater site.
