  • Portable protocol stacks compliant with protocol standards as published by the key standards bodies around the world (ITU, ETSI, ANSI, IETF, 3GPP).
  • Supplied as source code.
  • Used by over 400 global, industry leading telecommunications equipment manufacturers and OEMs.
  • Backed by over 20 years of protocol development expertise and 40 years of telecom software expertise.

DCOD-Bricks are a suite of software products belonging to ENEA Netbricks product line that provide powerful capabilities of non intrusive analysis. They operate over recorded digital communications in order to extract user data that are transmitted using a wide variety of telecommunication protocols.

DCOD-Bricks are composed of several modules that perform one specific protocol monitoring and decoding in order to extract transported user data.
DCOD-Bricks 3G 324 is a software library designed to operate (on line or off line) processing of digital multimedia sessions (typically DS0 64Kbps channel) between 3G mobiles or 3G mobile and servers. It performs:

  • Monitoring of session control protocols defined in ITU-T H.245 and ITU-T H.324.
  • Generation of an event log file that includes all events related to multimedia session control: master/slave determination, terminal capabilities negotiation, logical channel opening, multiplex entry exchange.... This event log file provides a global view of the session progress.
  • Generation of a message log file detailing content of all H.245 messages that have been exchanged during the session. This report includes decoded ASN 1 part of such messages to give access to all features of the recorded multimedia session.
  • Media flow extraction. De-multiplexing of logical channels combined in the recorded session is performed in accordance with ITU-T H.223 to restore media (audio and video) flows transmitted in both directions. For each direction media flows are stored in one 3GP file or in separate audio (AMR) and video (H.263, MPEG4) files for possible subsequent processing. A timing log file is also generated providing time stamping on start and stop of media flows.
