Specification Objectives This specification describes a cost and space saving equipment practice for data transmission equipment taking into account the current progress in DCE and DTE technology. It specifies the mechanical require- ments f

10、or plug-in data transmission equipment and the mechanical, functional and electrical characteristics of the interface between such equipment and associated equipment in which the plug-in equipment is intended to be used - in subracks, - in telephone sets, - in stand alone housings, - in DTEs. The me

11、chanical requirements of the specification are based on existing IEC standards for connectors, printed circuit boards (PCBs) and subracks. For the electrical and functional part of the Interface reference is made to the relevant standards of CCITT and ISO. As an alternative to the CCITT Recommendati

12、ons for electrical characteristics a new electrical characteristic for the interchange circuits is introduced which complies with integrated circuit technology. This specification shall ensure mechanical and electrical compatibility of plug-in data transmission equip- ment and its associated counter

13、parts. In particular, the following items are specified: - Size of PCBs, - Size of Plug-in Unit, - Type of connector, - Pin allocation, - Electrical characteristics of interchange circuits, - Electrical requirements for the power supply, - Environmental conditions. In this specification the applicat

14、ion of the equipment practice to plug-in equipment with V.- and X. -Series Interfaces (Modem and baseband equipment) is elaborated. The application of this specification in other transmission equipment (e.g. multiplexers) is also possible. In that case parts of this specification may not be relevant

15、 (e.g. pin ailocation of V.-Series interchange circuits) and the term DCE may be replaced by the term data transmission equipment where appropriate. Details will be given in the appropriate equipment specifications. _-_- e Edition of November 15, 1986 1.2. 1.2.1. Card Size DCE Width Note 1 Note 1 10

Note 2: For some applications a larger card than specified herein as types I and II is needed. For the time beeing there is no harmonized version of such a card. Current proposals of

19、different cards are to be found in Figures 2.4 (T/CD 01-14), 2.5 (T/CD 01-14), and 2.6 (T/CD 01-14). Study is underway as matter of urgency to define a harmonized version. 1.2.2. Applications The following types of applications are envisaged subject to national regulations. Plug-in unit for - DTEs (

Note: There are two candidates of connectors with inverted pin assignment under discussion: IEC 48B (C.0.)137, the so called DIN-version and IEC 48B (C.O.) 138, the so called Ericsson version. A definite IEC number for the one or the other connecto

If a DTE or a rack is intended to accept DCEs with the one or the other type of connector, the differences in the mechanical dimensions should be noted.
