What is an immediate trigger?
A relocator may receive an immediate trigger to a link from previously filed PCN sites. In the above drawing, the link is depicted with the proximity threshold box. There is a range of mountains in the top right corner. Company A deploys a co-channel non-interference to the link, and is not forced to relocate it. Company A PCNs the sites in 1996, filing site data with the Clearinghouse on 7/4/96. Company B is forced to relocate the link. Either they have a co-channel license on the left-hand side of the mountains, or have a license in another block that is also co-channel to the link. Company B negotiates hard and long with the incumbent, getting an agreement date of 7/1/99. Company B registers the link with the Clearinghouse on 7/4/99. The Clearinghouse receives Company B link data, and it immediately triggers a pro-rata obligation from Company A. The group of sites indicated by the dots in the right corner. Because of the mountains, Company A proves agreement date is within one month
