NOTE 1 − Electrical format CMI-encoded, according to G.703.
NOTE 2 − For networks deployed with G.813 Option II clocks or G.812
Type II, III or IV clocks, STM-1 requirements apply to STM-1e.
NOTE 3 − STM-1 1 UI = 6.43 ns
STM-4 1 UI = 1.61 ns
STM-16 1 UI = 0.402 ns
STM-64 1 UI = 0.100 ns
STM-256 1 UI = 0.025 ns
