Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 3 RHEL Program Management 2012-05-03 04:59:39 UTC

Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 4 tvizirov 2012-05-07 08:47:49 UTC

Yes, 

Please include this in the next release. 

Thanks.

Comment 6 RHEL Program Management 2012-12-14 07:23:38 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 7 Dan Williams 2013-01-10 23:39:00 UTC

What specific ISDN hardware is being used?

Comment 8 Uwe Beck 2013-01-13 20:11:53 UTC

- AVM FRITZ!Card PCI v2.0
- AVM FRITZ!Card PCI v2.1
- AVM FRITZ!Card PCMCIA v2.0

Comment 9 Dan Williams 2013-01-18 18:20:11 UTC

Thanks; do those use the HiSax driver in the kernel?  At least from the information I can see, they do.  I have just purchased USB ISDN TA to better determine the amount of work it will take to better integrate IDSN support.

Can you provide any of the configuration settings you're using with your provider?  If there are sensitive items or passwords, obviously don't include those, but please indicate that they exist.

Thanks!

No provider for internet. We use ISDN for remote support. ISDN remote station can be
a cisco ISDN router, Bintec Bianca/Brick ISDN router or RHEL ISDN ippp0 interface.

Parameter we need:
- PAP/CHAP
- authentication by MSN
- callback via D-cannel
- dynamic channel bundling
- dial on demand
- BSDCOMP, VJ, VJCCOMP, CCP, LZS, LZS_MODE, MRU, MTU

Comment 11 Katherine Dubé 2013-03-18 15:00:30 UTC

Thank you for submitting this issue for consideration in Red Hat Enterprise Linux. After further consideration, Red Hat does not plan to incorporate the suggested capability in a future release of Red Hat Enterprise Linux. 

Based on our existing NetworkManager priorities, we will not be able to implement this on Red Hat Enterprise Linux 6. However, we will continue to work on your other request as outlined in BZ 602265.
