Example of Networking with SPE 
 
The following diagram shows an example of networking with Signaling & Payload Encryption (SPE) between two HiPath 4000 systems and one HiPath 3000 system. For SPE networking between HiPath 4000 systems, the CorNet-IP and SIP-Q V2 protocols can be used. SPE networking between HiPath 3000 and HiPath 4000 is only possible using SIP-Q V2.
