Thread-topic: Late Comment on D2.1

All,

I just want to inform everyone I submitted a late comment against D2.1. We are trying to adjust the resistance through a node and set current limit for powered mixing segments in clause 189, but it appears that clause 188 nodes do not have any specifications related to current tolerance, so I submitted the following comment. I am open to discussion on this topic.

Regards,

Michael Paul

188.9.1

Ensure that non-powered DTE can pass current without damage when connected to a powered mixing segment. DC resistance through an unpowered node is not specified.

Add a setcion after 188.9.1.3 (188.9.1.4) - TCI line powering current tolerance: The DTE shall withstand without damage the application of any current between -2A and +2A applied across TC1's BI_DA+ to TC2's BI_DA+ and TC1's BI_DA- to TC2's BI_DA-. Each DTE,
including mated connectors and compensation components, adds up to 150 mΩ to the mixing segment loop resistance.

Yes
