Dynamic Configuration Rules
2.5.4.2 HG 1500 Configurations
2.5.4.2.1 IP Trunking with TDM Terminal Points Only
A HiPath 3800 system is networked with another system via an IP trunking link with 32 B chan-
nels. The codec G.711 with a sample rate of 20 ms (without encryption) is used for the IP trunk-
ing link. This requires an STMI2 module (2 DSPs on board = 32 voice channels are supported).
Figure 2-8 IP Trunking with TDM Terminal Points Only
Calculation:
32 gateway channels via LAN 1 should be included in the calculation. If more than 16 channels
are required, the feature “Enhanced B Channels” must be activated. The signaling load must
also be taken into account.
With a permissible maximum points total of 980, this scenario is feasible. However, this sample
calculation does not apply for HXGS/R3. This is because the static configuration rules only al-
low a maximum of 16 channels per board card.
2.5.4.2.2 IP Trunking and HFA Clients
A HiPath 3800 system with 96 HFA clients and additional TDM subscribers is networked with
other nodes via an IP trunking link with 16 B channels. For 96 HFA terminal points, 15 gateway
channels with 0.1 erl per terminal point are required.
