ITU-T V.230

GENERAL DATA COMMUNICATIONS INTERFACE LAYER 1 SPECIFICATION

Organization:
ITU-T - International Telecommunication Union/ITU Telcommunication Sector
Year: 1988

Abstract: General
This Recommendation defines the layer 1 characteristics of a General Data Communications Interface (GDCI) between Data Circuit-Terminating Equipment (DCE) and/or Data Terminal Equipment (DTE). Applications include DTEDCE interfaces, DCE-DCE interfaces, and possible DTE-DTE interfaces (see Figure 1/V.230). The interface specification is based on the ISDN basic user-network interface defined in Recommendation I.430. The differences between the GDCI and the ISDN basic user-network interface provide for the different wiring configurations expected for these interfaces, and they provide a means by which equipment conforming to V.230 can identify whether it has been connected to an interface operating according to V.230 or to an interface operating according to I.430. The characteristics of the GDCI have been chosen so that it is possible to design terminals which are compatible with both I.430 and V.230, and so that inadvertent connection of I.430 equipment to a V.230 passive bus or of GDCI equipment to an I.430 passive bus will not result in passive bus malfunction.
Note - DTE-DTE interfaces are not defined by CCITT.
