directions to make up the ring. At each shelf (node) in the ring, the M1 OLIU will
connect to the M2 OLIU in one adjacent node, and the M2 OLIU will connect to the
M1 OLIU in the other adjacent node. Likewise, when the 1665 DMX is interfacing
with other equipment at low-speeds (OC-3, OC-12 or OC-48) using 0x1 protection,
the Function Group slot (A, B, C, D, or G) 1 will connect to Main 2 on whatever shelf
the 1665 DMX is being connected to. The Function Group slot (A, B, C, D, or G) 2
will connect to Main 1.
