Overview
The IP•Tube VF 2W E&M has balanced 2-Wire 600 ohm Voice Frequency interfaces that utilize a PCM CODEC to convert Analog Voice Band into Digital for 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.
The IP•Tube VF 2W VF E&M has one to four E&M balanced 2-Wire 600 ohm Voice Frequency interfaces with signaling such as Push to Talk Relay transfer. A PCM CODEC converts Analog Voice Band into Digital for transportover Ethernet packet services.
2-Wire Analog to IP Converter
2-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.
IP•Tube VF Standard Features
Dual LAN Interfaces
All IP•Tube VF models ship with dual 10/100 BaseT Ethernet LAN ports. The dual Ethernet interfaces provide for:
- Management interface on LAN port 2 when LAN port 1 is connected to a VPN tunnel
- Protector Option: Redundant Packet Path connections with Constant or Switch Over Criteria
Assured Delivery Protocol
In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless, the IP•Tube VF employs Engage’s robust Assured Delivery Protocol with the following benefits:
- Packet out of sequence detection and re-sequencing
- Duplicate skipping
- Lost packet retransmissions with configured delay
IP•Tube VF Optional Features
Protector OPTION -PRO
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated VoiceBand. The extension of the VoiceBand has a fault tolerant link that is configured to always on, or with switch over criteria.
Applications
Public Safety Radio Tower Wireline Audio over Packet Networks
MTR2000 MTR3000 EDACS over IP Ethernet MPLS
A primary application for the IP•Tube VF 2W E&M is the conversion of Voice Grade circuit interfaces, that connect Public Safety Radio Base Stations to concentrator hubs, into packets. The IP•Tube VF 2W E&M employs high resolution Analog to Digital circuitry that maintains the quality of the original audio signal.
The packetized Voice Band communication can be sercurely transported over Ethernet Packet services such as: xDSL, Cable, Cellular 2/3/4G LTE, MPLS, & WiFi
The IP•Tube VF 2W E&M interfaces directly to the 2 wire analog interface of the 2 Wire Wireline interface of a Radio Basestation, such as MTR2000 / MTR3000 / EDACS, facilitating the use of Ethernet / IP / MPLS networks to backhaul Analog Radio Tower locations.
