Red Hat Bugzilla – Bug 63508
Channel bundling in ISDN is not working
Last modified: 2008-05-01 11:38:02 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):
Steps to Reproduce:
1. Edit isdn-device -> advanced
2. check 'Use channel bundling'.
3. Try to activate the interface.
Cant't find any way to use channel bundling with isdn.
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.
