NEXEDGE™Multi-Site IP Networks

The network option leverages the power of IP to link up to 16
digital trunked sites together for wide area roaming and calling
capabilities. Scalable networks can be created over existing IT
assets, private microwave, spread-spectrum links or carrier
services using standard 10/100 Base-T Ethernet switches and
routers. IPSec VPN tunneling provides encrypted,
secure communications links within any IP network.
Subscriber units use advanced control channel hunting
algorithms, RF signal strength and digital signal quality (low
bit-error-rate) to automatically determine the best sites to
register on while moving through a network. The 60,000
Group ID and Unit ID network capacity is sufficient for large
organizations and multi-user system sharing.

NXDN®Trunked Mode

NEXEDGE™ trunked mode provides increased capacity,
enhanced call capabilities, improved security and faster
communications with less required user operation than
conventional systems. The system automatically assigns
channels for faster, efficient use of spectrum, allowing users to
concentrate on the job at hand. The 3,000 (each) Unit ID and
Group ID per-site capacity provides ample unit and fleet
organization capabilities. Group and Individual calls enjoy
complete privacy as other users in the system cannot monitor
the calls. The Priority Monitor feature will monitor for up to 4
high-priority talk groups and switch users to those calls in
progress so important calls are not missed. During peak
usage hours, system Call Queuing stacks call requests and
processes calls when a channel becomes available. System
operators can assign important individuals higher queue
priority and even pre-empt lower priority users for more
important dispatch and emergency calls.
