The basic situation is as following:

There is the feature IPDA at node 10-30-200. The feature is already configured with access points 17 and 18. It is assumed, that both access points are located behind a bandwidth limited WAN. This situation is described for the resource management in sector S171 (bandwidth limited) and in bandwidth unlimited LAN sectors S100 (Host) and S172 (access points). gateway sectors are necessary for HG 3570 and HG 3575 in the IPDA feature (S170, S175 and S176). The sector S172 is necessary, to describe the direct connection between both HG 3575 gateways. Sector paths must be defined for the HG 3575 gateways, to describe their location to the Host correctly.

The Frame Size for G711 is set to 20 ms for all HG 3570/75:

CHANGE-CGWB:MTYPE=CGW,LTU=1,SLOT=61,TYPE=ASC,PRIO=PRIO2,CODEC=G711A,RTP=20;
CHANGE-STMIB:MTYPE=NCUI2,LTU=17,TYPE=ASC,PRIO=PRIO1,CODEC=G711A,RTP=20;
CHANGE-STMIB:MTYPE=NCUI2,LTU=18,TYPE=ASC,PRIO=PRIO1,CODEC=G711A,RTP=20;

The Codec G729 should be used for a call between a Host terminal and an AP terminal. The Codec G711 should be used for a call between an AP terminal of access point 17 and an AP terminal in access point 18.
