BlackTube•CEP E&M
E&M Signaling and Voice over Packet Networks
Overview & Applications
The Black•Tube CEP E&M converts E&M Circuit interfaces into AES Encrypted Packets for secure interconnection over Ethernet packet networks. This conversion facilitates the interconnection of E&M 4-Wire Voice with 4-Wire Signaling 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 Black•Tube CEP E&M has one to three 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 transport over Ethernet packet services. | |
Black•Tube CEP E&M Management | |
Management Module Black•Tube CEP E&M isolates management and data plane functionality with the use of two separate processor modules. Management processor access is limited to encrypted sessions via SSH, or SNMPv3, that employ AES 256 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 Black•Tube CEP E&M 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 | |
Black•Tube CEP Features | |
Assured Delivery Protocol In order to assure high quality communications over networks with intermittent or noisy performance, such as Wireless, the Black•Tube CEP E&M employs Engage’s robust Assured Delivery Protocol with the following benefits: Protector OPTION -PRO The extension of the E&M 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 | |
A primary application for the Black•Tube CEP E&M is the conversion of Voice Grade circuit interfaces with Push to Talk, that connect Public Safety Radio Base Stations to concentrator hubs, into packets. The Black•Tube CEP E&M employs high resolution Analog to Digital circuitry that maintains the quality of the original audio signal.
