Carrier Access Overload Class

AMPS and CDMA (IS95) have something called Carrier Access Overload Class which allows the carrier to define who should have access to the system in an emergency. Its a 2 byte section of the NAM that would determine who had access in just a scenario like this.

It seems to have fallen to the wayside in use for some reason. As I know no phone I've seen of late even lets you program it in any more or even asks for it.

Some carriers implement their own take on this by maintaining a list of priority ESN/MIN/IMEI's etc. (nexhell calls it Public Service Value Package L3) that are registered to public safety and affiliated agencies to give them priority access.
