摘要： A dynamically configurable telephone 10 has an intelligent controller 42 which implements a communication protocol to receive commands and parameters and to transmit status indicative of particular phone features. Upon receipt of the parameters, the controller translates the parameters into configuration settings for the telephone and also stores the parameters in a non-volatile memory 44 if such is installed. The telephone accommodates many different country-specific requirements without hardware or firmware changes being made to the phone itself. The controller returns solicited or unsolicited status messages, or events, to a PABX 14 over a bit serial digital data link 12. An event can be indicative of error conditions, such as data packet errors, timeouts, or data storage errors. An event can also be a reply to a previously received command, such as configuration status, internal test results, a phone serial number or a controller firmware revision level.
摘要翻译：动态可配置的电话10具有智能控制器42，智能控制器42实现通信协议以接收命令和参数并传送指示特定电话特征的状态。在接收到参数后，控制器将参数转换为电话的配置设置，并且如果这样安装，则将参数存储在非易失性存储器44中。电话可以满足许多不同的国家特定要求，而不会对手机本身进行硬件或固件更改。控制器通过位串行数字数据链路12将请求或未经请求的状态消息或事件返回给PABX 14.事件可以指示诸如数据分组错误，超时或数据存储错误之类的错误状况。事件也可以是对先前接收的命令的回复，例如配置状态，内部测试结果，电话序列号或控制器固件修订级别。
