You can view CFA (carrier facility assignment) information for SONET, T3, or T1 facilities or for T1 channels that you own or lease. You can search for the facility you want to view in two ways:
You can search directly for a specific SONET, T3, or T1 facility or for a specific T1 channel. This is how you search if you're doing just one search or the first in a series of searches.
You can continue to search for other facilities. This is how you typically search if you've already completed one or more searches.
