[evlatests] Ant 20

[Rob Long]

Ant 20 was ALMOST ready today!  We had some network problems earlier 
which seem to have corrected themselves and everything has been 
reconfigured.

The problem found this afternoon was related to optical power levels 
from the D30X modules through the optical mux.  We tried 3 different 
muxes and had problems with each one.  Jerry is bringing those back from 
the VLA and we will troubleshoot them in the lab.  We should have one 
working and ready to install tomorrow (assuming the Murphy field doesn't 
track us down and pounce upon us!)
