MPT-1327 is the most widely used trunking system protocol. It

could provide rapid connection, various call types, flexible

grouping and dispatching, as well as convenient system and

user management functions. Examples of such features include

emergency and priority call management, status messaging,

dynamic regrouping of users, and data/text messaging.

Features

QH-1327 MPT-1327 Trunking System

Module design

For the convenience of upgrading and maintenance, HYT

QH-1327 MPT trunking system is module-designed.

Flexible networking

HYT QH-1327 provides a variety of networking interfaces.

Between control center and base stations, the connection could

be optical fiber or microwave. Among different systems, users

could choose from optical fiber, microwave and IP. More

connection choices enable QH-1327 to fit different network

scale requirements from a single base station system to a

nationwide network.

Multi-level failure tolerance

Multi-level failure tolerance is supported. Base stations are able

to work properly when malfunctions happen to control center or

the linkage between control center and base station. Base

station transceiver is able to operate as conventional repeaters

when the controller of base station failed.

Strong extendibility & compatibility

The system could be easily upgraded. The modular design of

the system enables users to just add modules to upgrade the

system capacity. Different control centers could be

interconnected to form larger network.

Fluent handover

HYT solved the handover problem while terminals moving

through different base stations’ coverage. So during handover,

the on going call will not be interrupted.

Connection to PSTN/PABX

The gateway to public communication system is provided.

128 bit Digital encryption (optional)

HYT could provide military level digital encryption solution for QH-1327 trunking system users to

meet the requirement of privacy.

GPS dispatching function (optional)

With optional GPS module, hand portables and mobile radios could achieve dynamic GPS

dispatching function. Dispatcher could dynamically monitor the position of GPS subscribers. HYT’s

GPS equipments transmit GPS data via traffic channel rather than control channel, so there won’t

be system jam.

Highlights

MPT1327 standard

8100 IDs within one control center

(maximum 30 control centers interconnection)

Subscriber management (registration,

authority, remote kill & revive)

Voice calls (individual, group, broadcast,

emergency & priority)

Data (status, short data & short message)

Optional telephone interconnection interface

Call queuing, pre-emption & diversion
