Warning:
Do not configure an ADM of a ring network using the optical interfaces on the same optical interface board (such as SLQ4, SLD4), because if the board is faulty, the ADM will fail in both directions. In this case, the optical interfaces at both ends of an ADM should be on two boards.
Table A-4 shows the types and parameters of the optical modules provided by SDH boards.
