Description Inger Karin Haarbye 2002-04-15 04:32:57 EDT
Description of Problem:

Skipjack-2 with updates.
In 'neat' I have marked 'Use channel bundling' when configuring my 'ISDN dialup
configuration' -> advanced.
When trying to activate the interface, only ippp0 is used, and only one channel.
No interface ippp1 is configured.

Version-Release number of selected component (if applicable):


How Reproducible:


Steps to Reproduce:
1.  Edit isdn-device  -> advanced
2.  check 'Use channel bundling'.
3.  Try to activate the interface. 

Actual Results:

Cant't find any way to use channel bundling with isdn.

Expected Results:

A possibility to use channel bundling, and some sort of interface to choose only
one channel or both.

It's not a bug.  
When the required bandwidth exceeds the capacity for one IDSN B-channel  
(64kbps) a second (slave) channel is connected according to the MPPP protocol.  
When the traffic decreases below one channel capacity, the slave channel is disconnected.

So if I am downloading a big file with 2 channels, I have no possibility to 
use only one channel from 6-7 o'clock when I'm expecting a telephone from my 
son? Might not be a bug - but most people want to decide when to use one 
channel, and when to use both. This means they have to make their own 
isdn-scripts after all.
