The DB4 and DB4X are the primary multiplexer units of Avara’s DynaFlex rugged access multiplexer platform. These units provide 4 x 2Mbit/s network interface ports that connect to a powerful, integrated, non-blocking cross connect switch fabric with timeslot interchange capabilities. It also supports extensive circuit protection functions and has the capacity to perform digital and analogue summing functions for point to multipoint applications.
Together with the extensive Ethernet switching functionality supported, the DB4 is an ideal solution for mission critical networks where deterministic timing, low jitter and predictable switching times are necessary and efficient use of available bandwidth is mandatory.
