G.703: Physical/electrical characteristics of hierarchical digital interfaces
Recommendation ITU-T G.703 specifies the recommended physical and electrical characteristics of the interfaces at hierarchical bit rates as described in ITU-T Recs. G.702 (PDH) and G.707 (SDH). The interfaces are defined in terms of general characteristics, specifications at the output ports and input ports and/or cross connect points, earthing of outer conductor or screen and coding rules.
