Attachment requirements for Data Terminal Equipment (DTE) to connect to public networks that have physical and electrical network presentations based upon the ITU-T V-series of Recommendations
The present document specifies the technical characteristics to be provided by terminal equipment to be connected to public networks presented at an ITU-T Recommendations V.10 [10], V.11 [11] (including X.26 [21] and X.27 [22]), V.12 [12], V.24 [13]/V.28 [14], V.35 [15] or V.36 [16] interface regardless of data rate. The objective of the present document is to ensure that no disturbance occurs to the public network. The present document contains the minimum set of requirements derived from the above set of ITU-T
Recommendations and is applicable for connection to X.21 [18] leased line and circuit switched, X.21 bis [19] leased lines, X.25, Frame Relay and SMDS plus any other public network service that may be presented on the same electrical interfaces.
NOTE: Not all of the above services are available in all countries.
A test is given for each requirement in the present document, including measurement methods. Requirements apply at the public network interface of the terminal equipment, which may be stimulated to perform the tests by additional equipment if necessary.
Terminal equipment may be subject to additional or alternative requirements depending on its functionality, in particular
if it supports a service that is considered to be a justified case for regulation of terminal interworking via the telecommunications network.
