Products & Services
Network Simulation Software
Network simulation software is designed to model the potential behaviors of computer networks.
Channel Service Units (CSU) and Data Service Units (DSU)
Channel service units (CSU) and data service units (DSU) are digital interface devices that connect end user data communications equipment to digital access lines. They also provide framing of sub-64 kbps customer access channels onto higher rate data circuits.
Time Division Multiplexers (TDM)
Time division multiplexers (TDM) share transmission time on the information channel among many data sources.
Network Clock Sources
Network clock sources are timing devices that use a signal from an atomic clock or other external reference source to set and maintain a central time for all of the elements in a network.
