Table 4-2 DIL-switches in compatibility mode
4.2.3.2 Setting the mode
Notice! The following information is only valid for the default setting of S7 (S7 = 0),
this means compatibility is disabled!
The mode of the electrical channel CH1 is set with DIL switch S0. The mode of
optical channel CH2 is set with DIL switches S1 and S2. The mode of optical
channel CH3 is set with DIL switches S3 and S4. If the OLM has only one optical
interface, S3 and S4 have no function.
4.2.3.3 Setting the mode of the electrical channel (CH1)
Mode “electrical channel with segment monitoring“
CH1 is set to this mode, when S0 is in position 0.
