cmV35DTEDCE is a read-only enumeration reporting whether a V.35 port is currently operating as a DTE or a DCE. An administrator checks this to confirm the port role matches the physical cable and connected equipment, since a V.35 circuit needs matching DTE/DCE roles at each end to establish a link. For example, if a V.35 circuit won't come up and both connected ports report cmV35DTEDCE as dce, the operator would recognize the role mismatch preventing clocking from being supplied.
