The present document specifies the technical requirements and conformance tests for connection characteristics of point-to-point 140 Mbit/s digital leased lines. These leased lines operate at: - 139 264 kbit/s providing an information transmission capability, without restriction on binary content, (D140U); and - 139 264 kbit/s providing an information transmission capability, without restriction on binary content, of 138 240 kbit/s, (D140S); the remaining 1 024 kbit/s provides an 8 kHz framing structure in accordance with ETS 300 337 (ITU-T Recommendation G.832) (see annex F).
