1. Wireless Phase 1 Solutions
There are three basic technical solutions:
NCAS (Non-Callpath Associated Signaling)
CAS (Callpath Associated Signaling)
Hybrid CAS (CAS to SR, NCAS to PSAP)
NCAS uses more individual components (no change at PSAP)
CAS requires higher levels of signaling in the network
Hybrid CAS is in between (may be no change at PSAP)
NCAS is seen by some as the `default standard’, because the others require network upgrades to be workable
