1.2 Software Applications
The TB7300 operates in both P25/AS-IP and DMR/MPT networks. Within
these networks, the base station utilizes distinct P25/AS-IP and DMR/MPT
software applications.
1.2.1 Base Station Features
The following is a list of base station features for both P25/AS-IP and
DMR/MPT/MPT software applications:
P25/AS-IP ■ Fully compliant with the P25 Common Air Interface. Can therefore
interoperate with any similarly compliant radios
■ Supports P25 Phase 1 conventional operation with C4FM modulation
on the transmitter
■ Supports simulcast operation with P25 phase 1
■ Analog conventional repeater operation
■ Analog conventional simulcast operation on an IP backbone requiring
no audio calibration or training
■ Analog or digital console support in analog FM and digital P25 modes
■ Integrated built-in voting facility. No external voter is needed.
DMR/MPT ■ Fully compliant with the DMR Tier 2 conventional and Tier 3 trunked
standards. Can therefore interoperate with any similarly compliant
radios.
■ Analog conventional repeater operation
■ Operation as control channel or traffic channel transceiver in MPT/
MPT-IP networks, including standalone operation
■ Digital simulcast operation
DMR firmware does not support simplex operation.
Non-Application
Specific
■ Can be completely managed remotely from a PC running a web
browser: configuration, alarm monitoring, fault diagnosis, syslog,
feature and firmware upgrades. Alarms can also be reported via SNMP
traps, allowing integration with an SNMP-based network management
system.
■ Rugged construction with generous heatsinks and fan-forced cooling
for continuous operation from –30°C to +60°C (–22°F to +140°F)
■ Supports an analog 600 Ohm connected repeater in an analog
conventional network with CTCSS or DCS subaudible signaling
