Physical InterfaceThe instrument supports electrical port and optical port. In SDH test mode, physical interfacecan be selected as optical port-”O” or electrical port- “E” while consistent ports are required forreceiving or transmission i.e. both ”O” or both “E”. In PDH test, only electrical port-“E” is available.For the physical interface setup, see Figure 2-14 as follows:12
