IP Telephony (Voice over IP)
Branch performance requirements
Four gateway channels via LAN interface 2 with AES encryption should be included in the cal-
culation. As described in Table 10-9, eight gateway channels are required for 30 IP workpoint
clients (at 0.1 erlangs/workpoint client). Since VPN functionality is required, the WBM setting
"Enhanced B Channels" is deactivated.
The determined resource requirement of 696.1 points is less than the overall performance of
780 points which the HXGR3 board can provide. The branch configuration is feasible.

4 x 89.0 = 356.0
Voice gateway channel over LAN interface 1 without encryption:
8 x G.711 (received: 20 msec/sent: 20 msec) 8 x 39.0 = 312.0
Total = 696.1
