A cell site on Digicel's network can have up to as much as six sectors.
The direction of the serving cells can be changed based on the area that the site has to serve. If an additional sector is added, the PCI and Sector ID may not necessarily be in chronological order. For e.g. if a 4th sector is added at a later date, the Sector ID may be labelled as x6 instead of x4 and the PCI may just be a random number different from the order of the original 3 sectors.
