As soon as the bandwidth of the D-channel is no longer adequate for data trans-
mission, B-channels are added and data transmission takes place exclusively
in the B-channels (Dynamic ISDN). This change to B-channel mode or the ad-
dition of another B-channel can be made on the basis of throughput measure-
ment or triggered via packets of IP-based applications. This is implemented in
X3200 by an advanced configuration option in the IP subsystem. An interface is
assigned filters, rules and rule chains similarly to the IP access lists (see
chapter 7.2.8, page 286 ). These rules can be used to determine whether addi-
tional B-channels are to be set up for certain protocols, ports or IP addresses,
or whether data transfer is to take place exclusively in the D-channel.
How is AO/DI Configured?
The following steps are necessary for configuring X3200 for AO/DI:
■
Carry out X.31 configuration, i.e. reserve the TEI (Terminal Endpoint Iden-
tifier) value for X.25 (Packet Switch) (see "X.31 configuration", page 195 )
■
Carry out X.25 configuration (see "X.25 configuration", page 195 ):
– Link configuration for Datex-P
– Call routing
■
Configure AO/DI partner as WAN partner (see "Configuring AO/DI partner
as WAN partner", page 197 )
– Select PPP parameters
– Define the PPP interface as AO/DI interface
– Enter X.25 destination address for initial connection setup
– Control Bandwidth on Demand (dynamic B-channel bundling)
– Control BOD for IP-based applications
Please note the following when carrying out X.25 configuration:
Some of the X.25 parameters must be adapted to the X.25 network connected.
For Datex-P, the Windowsize/Packetsize Neg. field must be deactivated using
the Setup Tool.
For X3200 , the X.25 software is designed as an X.25 switch. This switch must
be appropriately configured for AO/DI (see "X.25 configuration", page 195 ).
