Advanced Configuration of the Basic Unit with the Setup Tool

ended after connection setup, it represents a permanently available (always on)
connection to the provider.
As soon as the bandwidth of the D-channel is no longer adequate for data
transmission, B-channels are added and data transmission takes place
exclusively in the B-channels (Dynamic ISDN). This is implemented in X4000
by an advanced configuration option in the IP subsystem. An interface is
assigned filters, rules and rule chains similar to the concept for IP Access Lists
(see User’s Guide, chapter 9.2.8 "Filters (Access Lists)". These rules can be
used to determine whether additional 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 X4000 for AO/DI:
■
Carry out X.31 configuration, i.e. reserve the TEI (Terminal Endpoint
Identifier) value for X.25 (Packet Switch) (see "X.31 configuration",
page 209 )
■
Carry out X.25 configuration (see "X.25 configuration", page 209 ):
– Link configuration for Datex-P
– Call routing
■
Configure AO/DI partner as WAN partner (see "Configuring AO/DI partner
as WAN partner", page 211 )
– 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.
