Black•Tube VF
4-Wire Analog Over IP
Overview & Applications
4 Wire Analog Voice Frequency over Packet NetworksThe BlackTube VF has balanced 4-Wire 600 ohm Voice Frequency interfaces that utilize a PCM CODEC to convert Analog Voice Band into Digital that is AES encrypted for secure transport over Ethernet packet services. This conversion facilitates the interconnection of Voice Band communications over cost effective and ubiquitous Ethernet based LAN/WAN/MAN wired and wireless network services such as MPLS, xDSL, Cable Modem and 4G/LTE. | ||
4-Wire Analog to IP Converter4-Wire leased line analog networks interconnect VoiceBand Communications for Utilities, Municipalities and Public Safety Agencies. Cost and availability issues with these copper telephone lines make finding transport alternatives a priority. Converting VoiceBand interfaces to packet data is a cost effective and easy to implement alternative. BlackTube VF Standard Features
Dual LAN Interfaces All BlackTube VF models ship with dual 10/100 BaseT Ethernet LAN ports. The dual Ethernet interfaces provide for:
Assured Delivery Protocol In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless, the BlackTube VF employs Engage’s robust Assured Delivery Protocol with the following benefits:

Applications
| |
Public Safety Radio Tower Wireline Encrypted Audio over Packet Networks A primary application for the BlackTube VF is the conversion of Voice Grade circuit interfaces, that connect Public Safety Radio Base Stations to concentrator hubs, into packets. The BlackTube VF employs high resolution Analog to Digital circuitry that maintains the quality of the original audio signal. The packetized Voice Band communication can be transported over Ethernet Packet services such as: • xDSL • Cable • Cellular 2/3/4G LTE • MPLS • WiFi
The BlackTube VF interfaces directly to the 4 wire analog interface of the 4 Wire Wireline interface of a Radio Base station facilitating the use of Ethernet / IP / MPLS networks to backhaul Analog Radio Tower locations. |
