Abstract: Status and alerting signals are distributed in a TDM communication system in a split-up form in broadcasting mode: the cadencing information of all status/alerting signals is distributed in word format on an existing signaling channel, each bit of such a word representing the scan value of a different status/alerting signal at a given moment. The basic tone common to all status/alerting signals may be distributed in coded form on a special or a common channel like voice signals. Any terminal instructed to do so will regenerate any required tone signal for itself.

Abstract translation: 状态和告警信号在广播模式下以分割形式分布在TDM通信系统中：所有状态/告警信号的节奏信息以现有信令信道的字格式分布，这样一个字的每一位表示扫描 在给定时刻不同状态/告警信号的值。 所有状态/告警信号共同的基本音调可以以特定或公共信道（如语音信号）的编码形式分布。 任何指定的终端将自动重新生成任何所需的音调信号。
