Abstract: A dialling discriminator which may be connected to a receiver unit and which is adapted to distinguish between incoming decimal and arrythmic dialling signals. A first polarity sampling is made 130ms after the receipt of an incoming signal. If the sample is negative then decimal dialling is indicated since arrythmic dialling, by definition, is always positive at this point. If the sample is positive, however, no decision can be made and a second polarity sample is taken at 160ms. If this second sample is negative then arrythmic dialling is indicated, since same is always negative at this point while decimal dialling is always positive.

Abstract translation: 拨号鉴别器，其可以连接到接收器单元，并且适于区分输入的十进制和arrythmic拨号信号。 收到进入信号后，第一极性取样130ms。 如果样本为负，则表示十进制拨号，因为根据定义，arrythmic拨号在这一点上始终为正。 然而，如果样品是阳性的，则不能做出决定，并且在160ms时取出第二极性样品。 如果第二个样本为负，则表示arrythmic拨号，因为在这一点上总是为负，而十进制拨号总是为正。
