2.17.7.1. Basic Situation 
Figure 38. Resource management for IPDA configuration with TDM & HFA phones
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. The feature HFA is configured
in AP18. 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 WAN for HFA is connected to the location of the displaced shelf.
This situation is described for the resource management in the way, that
the WAN sector 180 borders on the sector 172 and from the other side
on sector 181 to which the HFA cluster 81 is connected.
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.
CHANGE-SDAT:STNO=7240,TYPE=DATA1,CLASSMRK=G711&G729A&EC; CHANGE-SDAT:STNO=7280&&7282,TYPE=DATA1,CLASSMRK=G711&G729AOPT&EC;
All HFA subscribers have the attribute “DMC allowed”.
CHANGE-SDAT:STNO=2420&&2421,TYPE=ATTRIBUT,AATTR=DMCALLWD;
The IPDA gateways should support DMC.
- HG 3570:
CHANGE-SIPCO:TYPE=DMCDATA,DMCALLWD=YES;
CHANGE-CGWB:MTYPE=CGW,LTU=1,SLOT=61,TYPE=DMCDATA,DMCCONN=45;
- HG 3575:
CHANGE-STMIB:MTYPE=NCUI2,LTU=17,TYPE=DMCDATA,DMCALLWD=YES,
DMCCONN=45;
CHANGE-STMIB:MTYPE=NCUI2,LTU=18,TYP=DMCDATA,DMCALLWD=YES,
