Notice!
- From LSN module software version 1.0.35 onward, you can operate LSN improved elements
and LSN classic elements in combination in a loop or in a stub.
- If an LSN classic element is present, only 127 elements can be used in the loop.
- T-tap topologies are only possible if only LSN improved elements are used. As soon as an
LSN classic device is in a loop or stub, T-taps are no longer possible.

Stub topology
Each LSN element provides a built-in isolator between the b1 and b2 connectors. The current
flows through the LSN element between b1 and b2. Therefore, the last element of the stub
has only incoming but no outgoing cable. Unlike for the loop topology, the direction of the
current flow remains the same.
