本标准描述了通过交换电话网络运行的公用遥测服务（UTS）体系结构。所描述的UTS体系结构是一种基本的传输体系结构，能够支持多种不同的应用。遥测呼叫可以从终端用户A？上的实用程序/增强服务提供商（ESP）或遥测接口单元（TIU）发起？这是前提。为该服务定义的两种访问方法是 _中央办公室服务单元（COSU）访问方法和 _直接拨号接入法 为该服务定义的两种TIU传输方法是 _脱钩传动方法及装置 _钩上传动方式。 本标准所涵盖的体系结构是根据基本的公用事业抄表/控制服务来描述的。 但是，可以使用遥测传输服务交付任何数量的其他应用程序。本标准不包括这些其他应用。

This standard describes a utility telemetry service (UTS) architecture operated over the switched telephone network. The UTS architecture described is a basic transport architecture capable of supporting many different applications. Telemetry calls may be initiated from either the utility/enhanced service provider (ESP) or the telemetry interface unit (TIU) on the end userÕs premise. The two access methods defined for this service are _Central office service unit (COSU) access method and _Direct dial access method The two TIU transmission methods defined for this service are _Off-hook transmission method and _On-hook transmission method. The architecture covered in this standard is described in terms of a basic utility meter reading/controlling service. However, any number of other applications can be delivered using the telemetry transport service. These other applications are not covered in this standard.
