本标准规定了数字增强无绳通信（DECT）固定部件（FP）的一套技术要求，该固定部件支持通过ISDN接口连接到支持终端移动性的网络。本标准第1部分规定了DECT空中接口和为ISDN接口定义的移动性管理协议之间的互通程序，以支持CTM移动性。本标准（DEN/DECT-010066）第2部分规定了DECT空中接口和为增强ISDN接口定义的移动性管理协议之间的互通程序，以支持GSM移动性。 ETS 300 434包含支持基本呼叫的互通要求。

This standard specifies a set of technical requiremens for Digital Enhanced Cordless Telecommunications (DECT) Fixed Parts (FP) supporting connection, via an ISDN interface, to a network supporting terminal mobility. This part 1 of this standard specifies the interworking procedures between the DECT air interface and the mobility management protocols defined for ISDN interface, to support CTM mobility. Part 2 of this standard (DEN/DECT-010066) specifies the interworking procedures between the DECT air interface and the mobility management protocols defined for an enhanced ISDN interface, to support GSM mobility. The ETS 300 434 contains interworking requirements for the support of basic call.
