2.2 DESCRIPTION
The Model 3004-ECB series are self-powered elastic buffers, which
enable the connection of two independently clocked DCEs. When two
internally clocked devices exchange data and cannot be clocked externally,
the 3004-ECB is used as an interface between them. The Model 3004-
ECB utilizes two buffers to reduce errors caused by clock drift between the
two DCEs. All models employ adaptive buffer control. Internal buffers will
automatically adjust to "almost full" in the case of underflow or to "almost
empty" in case of overflow. All models perform the necessary "cross over"
wiring connections between the two DCEs. Installation is easy and
straightforward.
