The following table lists the possibilities that HiPath 3000/5000 offers for networking systems, zones, and domains.

 Table 10-2   Protocols for TDM and IP-based networking
 Protocol  
 Remarks  
 Example uses  
TDM-based  
CorNet-N  
Signaling protocol for digital communication between Unifycommunication 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 Unifycommunication 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.
