142 NetWare MultiProtocol Router for ISDN 3.1 Installation and ISDN Configuration Guide
Default: V.42bis
Options: No Compression, V.42bis
When data compression is performed on the ISDN-Controller,
the server memory is not burdened with this task. Per B channel,
128 bytes are downloaded on the ISDN-Controller.
33. Check Channel On Demand .
If a large amount of data packets is to be transferred, it may be
favorable to use more than one data channel to accelerate trans-
mission. By bundling the data channels the bandwidth can be
increased considerably.
Channel On Demand allows flexible use of the available ISDN
data channels on one ISDN-Controller by automatically activat-
ing the required data channels if a large number of data packets
has to be transferred.
If you have more than one AVM ISDN-Controller installed and
configured on your router, refer to Step 36 below, "Multi-Con-
troller Bundling".
When two or more channels are bundled on demand, the connection
charges are of course multiplied by the number of data channels used.
Please keep this in mind when configuring this parameter.
If you want to use Channel On Demand, the required data channels
must be available for this connection on the ISDN-Controller of both the
local and the remote site. For more information on this, refer to Chapter
14, section "Static Bundling and Channel On Demand" in this Guide.
Default: Disabled
BRI: Options: Disabled, Enabled
PRI: Options: Disabled, 1 B Channel, 2 B Channels,
3 B Channels, ..., 15 B Channels
If Channel On Demand is disabled, only one data channel is
used for an ISDN connection, irrespective of the number of data
packets transferred. The other data channel(s) available on the
ISDN-Controller may be used separately by other ISDN Call
Destinations for the other interface(s).
If Channel On Demand is enabled on an AVM ISDN-Controller
for BRI, the second data channel is switched through automati-
