Calculation for each individual branch office (HiPath 3500/3550):
4 gateway channels via LAN2 with AES encryption, and 8 gateway channels from HFA tele-
phones to the local ISDN CO (via LAN1) must be calculated. The signaling load must also be
taken into account.
Table 2-52
Calculation for Each Individual Branch Office (HiPath 3500/3550):
Signaling: IP phones (without H.235)
Signaling: PBX networking channels (without H.235)
Gateway channels: payload (G.711/20ms)
Voice channels: G.711 with VPN and AES
Total
With a permissible maximum points total of 780, this scenario is feasible for the branch offices.

Standalone System with Home Offices connected via VPN
8 home offices are to be connected to a HiPath 3800 system. Teleworkers use G.723 with a
sample rate of 30 ms. Data can also be transferred at 512 Kbps in both directions via a 1-Mbps
SDSL connection. The average packet length is 500 bytes. VPN should be used with AES en-
cryption. This configuration requires 1 STMI2 (2 DSPs on board for 32 channels).

Performance calculation:
G.723 is generally configured for home offices. As VPN is required for the DSL connection, the
option "Enhanced B Channels" must be deactivated. The HFA terminal point signaling load
must also be taken into account.
