Properties
● Each ↑ FDnet line card has two ↑ line drivers, which each support two ↑ loops
or four partial loops.
● A loop can be divided into two partial loops on the integrated line card with the
loop extension (FDnet).
● The additional line cards (FDnet/C-NET) FCL2001-A1 have the loop extension
permanently built-in by default.
