BlackBond E1
Circuit Encryptor


Voice Encryption

Secure Sensitive Voice, Video and Data Communications

The Engage BlackBond E1 has proven itself for over a decade as an ultra secure encryptor of E1 circuits.  Sophisticated organizations that transmit mission critical sensitive information over leased or dial-up E1 lines utilize the BlackBond E1 to keep their communications private.  Voice Encryption is the primary application for E1 Encryption.

The alignment of the E1 frames to AES blocks makes the BlackBond a very robust error tolerant encryptor of sensitive E1 Voice, Data and Video.

Additionally for Point to Point E1 links the BlackBond E1 adds a physical layer of E1 encryption security to data networks.

The Engage BlackBond E1 is a Commercial Off the Shelf E1 Link Encryptor that utilizes the Advanced Encryption Standard to Secure Sensitive Information Transmitted Over Point to Point or Dial-up E1 Communication Links for:

  • Health Care Industries 
  • Financial Institutions
  • Multi-Site Commercial Enterprises
  • Homeland Security
  • Public Safety Networks
  • National, State and
    Local Governments
  • Department of Defense

Proven Interoperability

The BlackBond's E1 interface has over a decade of proven interoperability with the full range of E1 communication equipment including:

  • WAN Bridges and Routers
  • PBX Trunks
  • Video Codecs
  • Voice and Data Multiplexers
  • Cellular Base Stations

Encryption Method

The Advanced Encryption Standard (AES) is utilized by the BlackBond to secure E1 circuits, especially for Voice Encryption. The AES algorithm is a symmetric block cipher that encrypts and decrypts information. AES is a FIPS approved symmetric encryption algorithm that may be used by U.S. Government organizations (and others) to protect sensitive information.

Key Management

Automated key management configurations ensure timely key transitions and eliminate the operational and maintenance costs of managing an encrypted network with manual key distribution.
