ATIS 0700706.1997 (S2017)

This standard defines and describes the Enhanced Priority Access and Channel Assignment (PACA-E) service for PCS. This service is intended to provide preferential treatment to a special group of PCS users, e.g., National Security and Emergency Preparedness (NS/EP) users. PACA-E requires modifications to basic PCS call set-up procedures in order to provide prioritization, by queuing, of the assignment of radio channel resources involved in call origination from PACA-E subscriber (priority access) and, separately, call delivery to a PACA-E subscriber (priority egress).
