Scope

This standard specifies signal quality requirements for serial data terminals at the interface between the synchronous data terminal equipment (DTE) and the data circuit terminating equipment (DCE). The interfaces involved in this standard comply with GB1454[V.24 (telephone network)], GB 11594[X.24 (data network)]], as in the following national standards or CCTT recommendations on DCE: (GB 7621 (V.22bis, V. 27ter, V.29, V.32, V.33; or GB 11599 (X.21bis) used together with GB 3455 (V.28) electrical characteristics or GB 3455 (V.28)/GB 9412 ( V.35) GB 7619 (V.11) as stipulated in X.22 used together with the electrical characteristics. It is also considered that in the development process of ISDN, there will be on the ISND reference point R according to V.110, V. 30 and X.21 stipulated V-series and X-series type interfaces. The rate limit is determined by the relevant DCE of DCE in the international CCTTTX series (such as X.10) and V series (such as .8, V.6). It is recommended to determine. The signal quality requirements stipulated in this standard are limited to the synchronous transmission of the interface with synchronous DCE. The signal quality related to the step-by-step DTE is not an integral part of this standard. This standard considers that according to the signal code used at the interface To exchange the circuit type at the same time, it is necessary to classify the performance of the signal quality, and to consider the timing of two types, that is, the same direction timing and the reverse timing. The division of the signal quality category is based on the timing between the data signal and the timing signal. , jitter, duty cycle and timing signal accuracy measurements. Exceptions are ISND reference point S/T applications. This standard is particularly required when interconnected equipment is provided by different organizations. This standard does not It is not intended to indicate actions to be taken when constraints are not met, but it attempts to provide a basis for negotiation between the parties involved. This standard does not describe the signal quality of DCEs or lines associated with them, nor does it describe possible Any requirements for acceptable bit error rates. This standard may also be used for direct DTE-to-DTE connections when referenced to interfaces using the following referenced standards
