Protocols for TDM and IP-based networking

Protocol	Remarks	Example uses
TDM-based
CorNet-N	Signaling protocol for digital communication between Siemens Enterprise Communicationscommunication systems.   Note: Systems should only be networked via CorNet-N if these are V4.0 or earlier.	•   Networking HiPath 3000 zones  •   Networking with HiPath 4000
CorNet-NQ	Signaling protocol for digital communication between Siemens Enterprise Communicationscommunication systems.	•   Networking HiPath 3000 zones  •   Networking with HiPath 4000
QSIG	Cross-manufacturer signaling protocol in accordance with ECMA and ISO	•   Networking with HiPath 4000  •   Networking with systems from other manufacturers
E&M	Signaling protocol for analog tie traffic	•   Networking with HiPath 4000  •   Networking with systems from other manufacturers
IP-based
SIP-Q V2	SIP-Q V2 (QSIG with CorNet-NQ tunneled via SIP)	IP networking with HiPath 2000 / HiPath OpenOffice EE, HiPath 3000, HiPath 4000, HiPath 5000, OpenScape Voice
	From HiPath 3000 V8 and HiPath 4000 V5 only the SIP-Q V2 protocol is used to IP network these two systems and the CorNet-NQ protocol is used for TDM networking. The CorNet-IP protocol is no longer supported.
