DTE and DCE
In the RS-232C interface specifications, the DTEs (Data Terminal Endpoint) shall be generally
connected with each other by a cross-mode cable; the DTE and DCE (Data Circuit Endpoint) shall be
connected with each other by a straight-mode cable.
The DTE is one piece of equipment connected at both ends of a communications line as a sender or
receiver of data (such as CU-8001/8002 on which the BHT is put and a host PC).
The DCE is one piece of equipment connected to the intermediate point between the DTE and the
communications line. It terminates communications lines and exchanges information between those
lines without any change in contents (such as modem).
