The basic situation is as following:

At node 10-30-200 there is the feature HFA. This feature is already configured. It is assumed that four (2x2) HFA subscribers lay behind a bandwidth limited WAN routes and two HFA phones are located in the local IP network of the Host. These routes are described for the resource management in sectors131/135 (limited bandwidth), sectors 132/136 (HFA in the local unlimited LAN) and the sectors 100/101 (local, unlimited network at the Host).The sector 101 is only used to describe a DMC connection between cluster 32 and 36.

Sector paths have to be defined, that a connection from sector 132N (136) to the Host can be calculated.

The HFA subscriber are set in cluster 32 (to S132), cluster 36 (to S136) and cluster 10 (to S100).

All HFA subscribers have the attribute “DMC allowed”:

CHANGE-SDAT:STNO=2420&&2425,TYPE=ATTRIBUT,AATTR=DMCALLWD;

The RTP-sample size has an influence on the bandwidth. All IP-phones in this documentation are using 20ms sample size for both G711 and G.729A. This can be configured in the database of the IP-phone or via DLS.
