JEDEC JESD12-5-1988 可测试性指南设计

(From JEDEC Council Ballot JCB-87-46, formulated under the cognizance of JC44 Committee on Semicustom Integrated Circuits.) The concern most often voiced by Application Specific integrated Circuit (ASIC) users is that of testability. Many vendors have taken steps to try to minimize the concerns of their customers but, to date, each company has instituted its own policies and the customers have seen little to ease their confusion. This document is composed of inputs from many IC manufacturers and some IC users. It is intended to bring together a coherent approach to dcsigriing for testability. It is not intended as a specification, nor is it to be interpreted as the only way to design. It should, rather, be used as guidance (as . the title implies) when designs are being initiated.

ITU-T Q.2-1988 宽带综合业务数字网(B-ISDN)概述 信令能力集1、版本1

The directives relating to 500/20-Hz signalling sets are provisional. An Administration intending to purchase new signalling sets for use on international circuits which for the time being are to be operated on a manual basis, may find it advantageous, by agreement with the Administrations interested in the operation of the circuits concerned, to use signal receivers and transmitters conforming to the specifications for international automatic equipment. This will permit a greater technical uniformity of installations and will avoid having to replace the signal receivers when,ultimately, these circuits are operated on an automatic or semi-automatic basis.
