(Part Number – CEP-040-VFEM-01) IP Tube VF 4 Wire E&M CEP – 4-Wire E&M Analog Over IP – 4-Wire Analog to Ethernet – Switches – BABA Certified Switches – BABA Switches – Made in USA Switches – Made in America Switches – Engage

Description

Overview

The IP•Tube VF 4W E&M CEP has balanced 4-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 4W VF E&M CEP has one to four E&M balanced 4-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.

4-Wire Analog to IP Converter

4-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 4W VF E&M CEP Standard Features

Dual LAN Interfaces

All IP•Tube VF 4W VF E&M CEP 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 CEP Management

IP•Tube CEPs isolate management and data plane functionality with the use of two separate processor modules. Management processor access is limited to SSH or SNMPv3 encrypted sessions that employ AES256 bit keys and sophisticated NIST passwords. These sessions may be established after authentication via TACACS+ or Radius.
The independent Linux based management plane of the IP•Tube CEP ensures Critical Infrastructure Data is isolated from management network access. The Management Module uses internal serial ports to connect to the Data Plane processor.

Administration and User Logs are available with Syslog.

CEP management security features include:

• Administrative policies for adding, removing, disabling and renaming authorized users; limiting user access to assigned commands; and enabling only desired port numbers.

• User authentication directly or in conjunction with TACACS+ or RADIUS servers including RSA SecureID support for two factor trusted compliance.

• An SSH command interface encrypting management traffic with powerful 256 bit symmetric keys and NIST based passwords.

• Support of the SNMPv3 protocol for secure connectivity to SNMP element managers.

• In addition, administrative accounting data can be reported to syslog servers with accurate timestamps provided by an NTP source.

IP•Tube VF 4W VF E&M CEP 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 4W E&M CEP is the conversion of Voice Grade circuit interfaces, that connect Public Safety Radio Base Stations to concentrator hubs, into packets. The IP•Tube VF 4W E&M CEP 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 4W E&M CEP interfaces directly to the 4 wire analog interface of the 4 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.
