17、TS 100 588 V8.0.1 (2002-05) 1 Scope The present document defines the structure of the physical layer (layer 1) of the BSS-MSC interface for supporting traffic channels. Use of the physical layer for supporting Signalling SystemNo.7 signalling links is covered in Technical Specification 3GPP TS 08.06
18、. The physical layer is the lowest layer in the OS1 Reference Model and it supports all functions required for transmission of bit streams on the physical medium. For the present document only digital transmission will be considered, the use of analogue transmission is a national concern. 2 Re fe re
