If you're doing just one search or the first in a series of searches, you can search directly for a specific facility or channel
by specifying a SCID (SONET Carrier ID) for an OC01, OC03, OC12, OC48, or OC192 SONET facility (If you try to search for an OC24 or OC96 facility, you get information for the parent OC48 or OC192 facility.)
When you find a facility that you've specified, you can continue to search for other facilities.
