Apparatus and methods enabling High Speed (HS) transport of Ethernet data frames via a Unified Dual-Scrambler physical interface is described. The physical interface is adapted to convey Media Access Control (MAC) layer data in a Local Area Network (LAN) on Metropolitan Area Network (MAN) configuration at 10.000 Gb/s and further adapted to convey MAC layer data in a Wide Area Network (WAN) configuration at 9.58464 Gb/s. Physical layer data transport is provided over a Synchronous Optics NETwork (SONET) / Synchronous Digital Hierarchy (SDH) concatenated OC-192 links at a 9.95328 Gb/s signal rate in selectable frame formats selected from a LAN/MAN data transport frame format and a WAN data transport frame format. The use of the LAN/MAN data transport format and the WAN data transport format on the Unified Dual-Scrambler) physical layer interface is enabled via a Simple Universal Physical Medium Dependent (PMD) Interface (SUPI).
