标准摘要
[中文适用范围]: 此修正案以增量方式增加模数编号(即序列号),最大值为2147483648,可以用31位表示。这通过引入一个新的“Set Mode”命令来实现,该命令可以在缺少默认值或覆盖默认值的情况下协商或指示模数。这利用了模式设置命令/响应中的可选信息字段。 [外文原描述]: This amendment increases the modulus number (i.e. the sequence number) in steps up to a maximum of 2147483648 which can be represented in 31 bits. This is done by the introduction of a new "Set Mode" command that can be used to negotiate or indicate the modulus in the absence of or to override a default value. This uses an optional information filed in the mode setting commands/responses.
