Darn. You are right. This step is only for back-to-back cabling. Not when using a
pair of csu/dsus.

Here is what Kentrox tech support said that got my 2 D-SERVs working together
back-to-back:
build a cable like this:
pair 1: 1 to 4
2 to 5
pair 2: 4 to 1
5 to 2
Set one unit to internal timing and the other to loop timing. Match all other
settings.
