Abstract: An ISDN switching system having facilities for testing an ISDN signal composed of B-channels and D-channels at least. The testing facilities can achieve a B-channel test and D-channel test selectively with simple construction by employing a converting unit in the system. The converting unit enables creation of a connection path between a test equipment and an object to be tested through an ISDN exchange and thus the ISDN signals for the test can be treated as usual ISDN signals. Thereby, the test equipment and the object can freely be connected to each other.

Abstract translation: 具有至少用于测试由B信道和D信道组成的ISDN信号的设施的ISDN交换系统。 测试设备可以通过采用系统中的转换单元，通过简单的结构选择性地实现B通道测试和D通道测试。 转换单元允许通过ISDN交换机在测试设备和要测试的对象之间建立连接路径，因此用于测试的ISDN信号可以被视为通常的ISDN信号。 因此，测试设备和对象可以自由地彼此连接。

Abstract: A heat-sensitive record material having on a base sheet a recording layer which comprises a basic colorless chromogenic material and an acceptor in the state of that the colorless chromogenic material is contacted with the acceptor by heating to produce color images. The recording layer comprises at least one phenol compound represented by the following formula (I) together with the colorless chromogenic material and the acceptor, ##STR1## wherein each of R.sub.1, R.sub.2 and R.sub.3 radicals is hydrogen, C.sub.1-8 alkyl or C.sub.5-8 cycloalkyl, but at least one of R.sub.1, R.sub.2 and R.sub.3 radicals is C.sub.5-8 cycloalkyl; and each of R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 radicals is hydrogen or C.sub.1-8 alkyl.
