- Data terminal equipment (DTE).
- Data circuit terminating Equipment (DCE) concept.
Most digital data processing device have limited data
transmission capacity and limited distance of data
transmission. DTE is the end user machine, generally refers
to (Devices) terminals and computers.
Example: Email terminal, workstation, ATM in a bank, sales
terminal in a departmental store. They are not commonly
connected directly to transmission medium.
DCE is used to connect the communication channel.
Example: modem. It interacts with DTE and provides an
interface of DTE to communication network transmits and
receive bits one at a time over the communication channel.
To specify the exact nature of interface between DTE and DCE
various standards and protocols have been developed. DCEs
and DTEs are connected in two ways. A high degree of
cooperation is essential in DTE-DCE combination, as data and
control information is to be exchanged. They can be
connected in two ways
- Point to point configuration: Here only two DTE devices
are in the channel
- Multidrop configuration: Here more than two devices are
connected to the same communication channel.
