Guys,

Someone just pointed out to me that an endspan PSE can use Alt-A, Alt-B, or both. (See paragraph 33.2.1) I had forgotten about this, assuming endspans were always Alt-A.

This would seem to complicate our plans to have endspans and midspans share the load. Midspans always use Alt-B, so they can share ONLY if the endspan uses Alt-A.

Does anyone know of any endspans that actually use Alt-B (the spare pairs)? If so, please reply.

Steve
