Features Supported by HiPath 3000/5000 V9 for Connecting to ITSPs 
 

Standalone and networked systems  
HiPath 3000/5000 V9 enables standalone and network systems to be connected to ITSPs.

Networked systems  
S0 connections and Internet telephony connections can be used in parallel in all networking solutions (HiPath 3000/5000 systems connected to each other or to HiPath 2000 systems / HiPath OpenOffice EE) to connect to ITSP analog lines.
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. H.323 protocol is no longer supported.
Important: IP networking between HiPath 3000 V8 and HiPath 4000 V5 has not yet been released and does not work if SPE is activated.  
Up until HiPath 3000/5000 V7, there was a central ITSP connection, i. e. one ITSP access in the entire network. From HiPath 3000/5000 V8 each node can have an ITSP access.

Internet telephony types  
ADSL and SDSL are supported.

ITSP connections with single-number registration  
Up to 30 user IDs (SIP client user accounts) can be set up on ITSP connections with single-number registration.

Maximum number of simultaneous calls  
The maximum number of simultaneous calls to the ITSP depends on the codec used and on the available bandwidth of the Internet connection. Up to 30 simultaneous calls are possible.
The maximum number of simultaneous calls is calculated based on the upstream rate and the bandwidth required for each call (128 Kbps).
[Number of calls = upstream rate (in Kbps) / 128 Kbps]

Least Cost Routing (LCR)  
Up to four simultaneously active/registered ITSPs are supported by the system for least cost routing (LCR). Depending on the bandwidth, more connections may be possible.

IP/IP e2e payload via enterprise proxy  
In HiPath 3000/5000 V7 R2 and later systems, "IP/IP e2e payload via enterprise proxy" is supported for Internet telephony. This means that for Internet telephony, no data packets need be processed by the system's digital signal processors. Calls are routed via LAN, router and ITSP. HiPath 3000/5000 sets up a call to the remote station. This means that no gateway channels (DSP channels) are required for ITSP connections.
