Q: Can I use SSN4SLO1602 on OSN6800 or OSN3800?

A: No, you cannot, only OSN8800 supports SSN4SLO1602, but please kindly note that OSN8800 UPS subrack cannot support SSN4SLO1602 either.


Q: Can I use SSN4SLO1602 in OSN8800 master or slave subrack?

A: No, it can be used only in an independent subrack, but not in a master or slave subrack.


Q: Why does SSN4SLO1602 cannot support SDH ASON in my OSN8800 T16 subrack?

A: Yes, when it is installed in a T16 subrack, the board does not support SDH ASON.
