14 Description TB9300 Installation and Operation Manual

1.2 Firmware Applications

The TB9300 operates in DMR/MPT networks.

1.2.1 Base Station Features

The following are lists of base station features available in both DMR/MPT

firmware and non-specific applications:

DMR/MPT ■ Fully compliant with the DMR conventional (Tier 2) and trunked

(Tier 3) standards. They can therefore interoperate with any similarly

compliant radios.

■ Analog conventional repeater operation

■ MPT operation as a control or traffic channel transceiver in an MPT-IP

network, including standalone operation

■ Digital simulcast operation

■ Support for an analog, 600 Ohm connected repeater in an analog

conventional network with CTCSS or DCS subaudible signaling

■ Simplex operation with antenna delay

Simplex operation applies to analog conventional operation only. DMR

operation does not support simplex.

Non-Application

Specific

■ Configuration, alarm monitoring, fault diagnosis, syslog capture, and

feature and firmware upgrades can be managed remotely from a PC

running a web browser. Alarms can be reported via SNMP traps,

allowing integration with an SNMP-based network management

system.

■ An integrated wiring solution is provided for the system control bus and

DC power connections to each module in the subrack

■ Reciters (receiver/exciter modules) can be replaced without affecting

the operation of other reciters in the same subrack

■ Rugged construction with generous heatsinks and fan-forced cooling

for continuous operation from – 30° C to + 60° C (– 22° F to + 140° F)

1.3 Firmware Application Details

In a DMR conventional network, the base station can operate as a stand-

alone repeater, or as a member of a multi-site system (under the supervision

of a DMR conventional channel controller). Since DMR provides two

concurrent logical channels (timeslots) for each radio frequency (physical

channel), the same frequency can be accessed simultaneously, one in each

timeslot. Base stations on different sites can be linked together to form
