TL-Net Protocol – Key Features
The main component of the BridgeCom network is the TL-Net protocol. TL-Net has been developed by Bridge-
Com Systems specifically for Multi-Site networking of LTR ,CTCSS, NXDN, Mototrbo®, NEXEDGE® and
many other formats.
Highlights of the TL-Net Protocol:
• Transmission trunking between sites. Remote sites are brought up as fast as handshaking with your local site.
• Conventional, LTR, Digital and almost any other format radio can be connected to the gateway to provide a network of
mixed modes. For example, a conventional group using CTCSS can talk to an LTR talk group and a Mototrbo® digital talk
group all at the same time accessing many sites on the network.
• Excellent audio quality. No loss of syllables on front-end or back-end of transmissions.
• Site specific calling. Give customers access to the sites they need.
• Push to register. Use sites only when needed.
• Uses existing standard LTR capable radios. No radio upgrades required.
• Networking equipment is easy to install and requires only one static or dynamic IP address per site.
• Both Server and Gateway can be configured to use dynamic DNS service.
• The Server and Gateway can be located behind a firewall.
• Network up to 20 repeater channels per site on just one IP address.
• Pass MDC 1200 and Fleetsync data between sites.
• Manage your entire system from any computer connected to the internet.
• Server-to-Server technology. Airtime service providers can connect their TL-Net systems together to create unlimited cover-
age areas.
• Windows based PC client support. Use a PC as a dispatch console or remote base station. Requires a Microphone, Speaker
and a network connection.
• Standard 10/100 Base-T switches and routers. Use the customers existing network equipment, no special networking equip-
ment required.
• Very easy system management. The Sys-op can use a web page based interface to manage the system.
• Virtual Private Networking can be used to create VPN tunnels between sites. The VPN tunnels provide a secure, encrypted
connection between sites. This is optional and is not required.
• The Ethernet IP network can be a Local area network or the Internet.
• Very little bandwidth is required. A variety of different Codecs can be used varying in bandwidth from 5.9k to 64k bits/
second resulting in end-to-end throughput of 16k to 80k bits/second per channel.
• Manage entire network from any computer with a web browser.
• Airtime usage data is in a ODBC compliant database. You can link your users airtime usage to Microsoft Excel, Access and
many other report generator programs. Airtime usage is also available from our web page interface.
• Both server and gateway are housed in a 2U rack mountable chassis
• Lowest cost per wide-area channel in the industry
