Calculation Example 2: 96 IP workpoint clients and 16 IP networking

connections to HiPath 3750, HiPath 3700

HiPath 3750 or HiPath 3700 with 96 IP workpoint clients (system clients) and additional TDM
workpoint clients are connected to another system via an IP networking path with 16 B chan-
nels. As described in Table 2-10, 15 gateway channels are needed for 96 IP workpoint clients
(at 0.1 erlangs/workpoint client). Codec G.711 with a sample rate of 20 ms without encoding is
required for the IP networking paths and the IP network clients.
An HXGM3 board with two PDM1 modules is necessary for this configuration:
2 DSPs per HXGM3 and 2 x 1 DSP per PDM1 = 4 DSPs, together supporting up to 32 chan-
nels.
Correspondingly, the total performance available is 980 points.
Performance requirement
Thirty-one gateway channels via LAN interface 1 should be included in the calculation. The set-
ting "Enhanced B Channels" must be activated for this via the WBM. The Virtual Private Net-
work VPN and Firewall functions are automatically deactivated when this setting is activated.
The signaling load has to be taken into account when calculating performance.

The specified performance requirement of 461.16 points is below the 980 total performance
points that the HXGM3 board can provide. The configuration is feasible.
