Ring 1 = Two-fiber BLSR
Ring 2 = Four-fiber BLSR
All protection for a two-fiber BLSR interconnecting to a four-fiber BLSR is performed at the line level.
You can make the connection with a simple 2-way cross-connect from the appropriate side, east or west,
of the two-fiber BLSR to the working fiber of the appropriate side, east or west, of the four-fiber BLSR,
as shown in Figure 2-41.

Use the command ENT-CRS-STS1:CISCO:STS-1-1,STS-5-1:CTAG5::2WAY;
to create a 2-way connection from 1/1/1 to 5/1/1, as shown in Figure 2-42.
