Core Networks

Voice communication and data communication have traditionally been very separate – different networks, different services, and different technologies. This has changed, as voice and data converge at all levels. Today, networks are designed to carry voice, data, and video media, resulting in innovative mixed media services. Critical to all of this, are the underlying core technologies essential to the evolution and convergence of mixed media in communications networks. TRA's Core Networks provides thorough coverage of switching and signaling technologies, found within the core of carriers' networks.
