Data Terminal Equipment

(communications, hardware)
(DTE) A device which acts as the source and/or destination of data and which controls the communication channel. DTE includes terminals, computers, protocol converters, and multiplexors.

DTE is usually connected via an EIA-232 serial line to Data Communication Equipment (DCE), typically a modem. It is necessary to distinguish these two types of device because their connectors must be wired differently if a "straight-through" cable (pin 1 to pin 1, pin 2 to pin 2 etc.) is to be used. DTE should have a male connector and should transmit on pin three and receive on pin two. It is a curious fact that many modems are actually "DTE" according to the original standard.

* End system to intermediate system routing information exchange protocol for use in conjunction with ISO 8208, data communications--X.25 Packet level protocol for data terminal equipment. The work that has been done in ISO TC97/SC6/WG2 on the requirements for Network Layer routing has led to agreement that the aspects of Network Layer routing that are concerned with communication between end systems and intermediate systems on the same subnetwork are separable from the aspects that are concerned with communication among the intermediate systems that connect multiple subnetworks.
