The Model 3004-MTE Series are self-powered tail circuit buffers, which enable the connection of two DCEs in a "tail circuit" configuration. A tail circuit adapter is required to couple two DCE devices whose clocks are of the same frequency but are not in phase. The Model 3004-MTE utilizes a single auto-centering buffer to prevent data errors caused by clock jitter and clock phase differences. All 3004-MTE models perform the necessary "cross over" wiring connections between the two DCEs. Model 3004-MTE installation is easy and straightforward.

The Model 3004-ECB Series utilize two buffers to reduce errors caused by clock drift between two DCEs. All 3004-ECB 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 3004-ECB models perform the necessary "cross over" wiring connections between the two DCEs. Model 3004-ECB installation is easy and straightforward.
