DTE and the digital network.

Data Terminal Equipment. The equipment, such as computers and printers, that provides
or creates data.

Data Terminal Ready. An EIA-lead standard for V.24 circuit CT 108; an input signal
(DTE-to-DCE).

communications industry to ensure uniformity of interface between DTEs and DCEs.

The EIA’s standards defining the 25-pin interface between the DTE and DCE.

MIB objects unique to Paradyne devices.

An excessive bipolar violation condition results when at least one invalid bipolar violation
