Models:

MV-1  - The MV-1 provides for a simple analog channel connection to a  TL-NET system.  The MV-1 adds one analog VOIP link to any analog or digital radio control station endpoint.  This product is useful in that it provides a less expensive solution when just one remote voice connection is required.

MV-IPSC1 –  The MV-IPSC1 functions as an endpoint that inspects incoming MotoTRBO digital call information (voice or data) and routes the call to other IP Site Connect sites as indicated by the talk map.  It provides for expanded linking and control of both times slots of a MotoTRBO repeater operating in IP Site Connect mode.  The MV-IPSC1 provides selective site-to-site group call routing capability which is not available with Motorola IP Site Connect. For example: If you have 15 sites of MotoTRBO repeaters using IP Site Connect, then the MV-IPSC1 can allow for placing a group call to only a select number of the sites, rather than all 15 sites.  The MV-IPSC1 requires no control station.  Digital audio and data packets are inspected from the IP port of the MotoTRBO repeater.  The MV-IPSC1 is to be used in conjuction with the TL-NET Server.

MV- I1 – The MV-I1 links digital audio from a MotoTRBO repeater operating in IP Site Connect mode to an analog connection such as LTR, Conventional, PC Client Dispatch or iDEN.  The MV-I1 provides for interoperability between MotorTRBO and virtually any analog radio system.

MV-IPSC75 – A single box design that connects 3 IP Site Connect networks (45 peers) effectively making IP Site Connect infinitely scalable.  Expandable to up to 5 IP Site Connect networks.  Both MotoTRBO repeater time slots are connected for both voice and data communications.

The MV series is highly configurable and can be tailored for your specific application. For additional information please use InfoQuest, be sure mention what you’re working with.  We can then provide a custom quote to meet your needs.

The primary purpose for HSMM and Hinternet is to augment emergency communications via long range high speed wireless data networks that can handle voice, data and video communications. HSMM can also be used in the day-to-day aspects of Amateur Radio Communications.

The Fit …

With the rapid expansion of Asterisk PBX into the relm of radio communications the added flexibility of having a wireless linking system has also expanded.

It is now possible to have a network of repeaters and link stations that never touch a standard public switched telephone network, yet at the same time this network of repeaters and link stations has all the standard features one will expect to find with any telephone system.

By integrating HSMM along with Asterisk PBX a truly transportable network can be delivered to any location where communications is needed, with voice, data and video all being available to the agencies and organizations being supported.

How Does It Work?

TL-NET combines all the features of single-site LTR with our VoIP backbone to provide a multi-site LTR trunking solution. All the benefits of single-site LTR are maintained except now it’s multi-site. All dispatch calls are made using transmission trunking. Setup between sites is extremely fast! In fact, just as fast as handshaking with the local site. Your customers will notice no difference other than their range is extended.

How Do I Use It?

Our system works with standard LTR® capable radios from Icom, Kenwood, Motorola, and many others. Use your existing equipment! No special option boards to install, firmware upgrades or special radio programming required. Each site’s Gateway supports a web server that allows you to control and monitor your system from a PC with an internet connection. From a web browser you can validate/invalidate talk groups, adjust TX voice and data levels, enable/disable network access and much more.

What Equipment is Required?

• Each site requires a high-speed internet connection which can be a T1, cable modem, or DSL.
• Each repeater site consists of one TL-NET Gateway and an array of repeaters. The Gateway connects your system to the internet and manages the audio channels to and from the repeaters.
• One TL-NET Server is required to oversee the entire network. The Server can be located anywhere.
• One TL-NET LTR controller is required per repeater. To meet this need we offer two choices: You can go with our CS-540TL-Net Repeater/Controller package, which combines our RF equipment with the TL-NET LTR controller, or you can purchase the TL-NET controller by itself to connect to your own RF equipment.
