Summary

This feature allows the PBX to provide basic connection service for interfacing with the other PBX by using Layer 3 protocol which conforms to ETS 300 172. ETS 300 172 is standardized for private telecommunication network as Inter-exchange signaling protocol for circuit mode basic services by European Telecommunication Standards Institute (ETSI). The Q-SIG protocol creates Layer 3 messages between Q reference points expected as conceptual point for inter- office signalling.
