Analog- and (Ro)IP-Gateway – Join™ VLC

Join™ VLC is a infrastructure gateway for the integration of any analogue interface into an IP or VoIP network. It provides features that allow unrestricted operation of different analog terminals and communication systems over an IP network. Special features of the operating modes are transmitted and interpreted transparently. One device unit contains two independent functional units, which operate simultaneously with two analog terminals in different operating modes.

  • Various redundancy concepts
  • Operation with or without server infrastructure
  • Centralized as well as decentralized solution conception
  • Robust construction
  • Various designs
  • Different operating modes
  • Digital inputs and contactors
  • Integrated serial interfaces
  • Reliable and legal documentation

Direct connection

In this example Join™ VLC is controlled directly by the dispatcher. This can be, for example, a redundancy concept or a low-cost solution.

Infrastructure with communication server Voxtronic Conex™

In this connection the gateway is controlled by a Conex™ server. A wide variety of redundancy concepts are possible, as well as centralized management using Conex™ TCMS.

Analog Radio and Digital Radio

Radio systems can be connected via 2-wire or 4-wire. The PTT button is controlled by contactors or by center tapping. An assignment of the channel is detected by digital inputs and signaled via contactors. Additional digital radio data (such as TETRA) can be transferred via RS232 or RS485 interfaces.

Public Address System (PAS)

Single-directional or two-way-directional public address systems are connected via the analog interface (2-wire or 4-wire). Join™ VLC can be used in conjunction with sonic applications with or without amplifier modules. External amplifiers are controlled via contactors and external contacts are evaluated via digital inputs.

Public Telephony and Company Telephony

Join™ VLC supports FXO/FXS operating mode for analog connection to public telephony (PBX), trunks (PSTN) and phones of company telephony. Features such as CLIP, CLIR, COLP, etc. are forwarded as transparently as DTMF tones and transmitted numbers.

Passive Connection (recording, voice documentation)

To record the communication traffic on analog lines without interference, Join™ VLC can be switched on with high impedance (operating mode high-impedance, passive). Depending on the security requirement, recordings can be encrypted and stored in compressed form and automatically transferred to another system and, depending on their relevance, deleted after a defined period of time.
