Telekom has now apparently a solution for the occurring for some time unwanted disconnection from the Internet. At least until this morning, but some all-IP connections were still affected.

After extensive testing, the German Telekom reports to have eliminated an annoying bug in their system. Some Telekom customers who have all-IP Internet connections, complained for a while about unwanted separation of Internet connection that occurred in the interval of 24 hours and 15 minutes. The error image looks like that, although the ATM or EFM PTM – connection is constantly (DSL synchronization exists), but the connection to the PPPoE server is cut short.

This corresponds exactly to the usual prior to the introduction of the all-IP connections forced separation, have hindered in private DSL connections by means of many network operators such as the operation of servers – a motive may have been, private business customer offers significant to separate tags. At one of H networks Connection observed the forced separation occurred in exactly the same interval until this Friday morning. However, the problem might be limited to outdoor DSLAMs with certain Infineon software.

On a DSLAM with software version 11.5.3 an associated all-IP connection was undesirable disconnected from the Internet. Another all-IP connection to a DSLAM with version 9.10.7.0 holding his Internet connection, however, as expected, without interruption, in this case, since the 16th of December. On demand, the company said now to have recorded this morning a network-wide software patch that will fix the problem for all connections. The company was open, however, which network element that caused the error

As with ISDN DSL combo ports: The router has the DSLAM indeed continue to raise my ATM respectively EFM (DSL synchronization exists for more than two days), but the IP connection was briefly separated after 24 hours and 15 minutes.

Before the All-IP era, forcing worked only on the Internet access and many customers felt thereby hardly disturbed, although by IP sessions lasted no longer than 24 hours – the start of a very long downloads you had to think carefully. Transfers that should last longer than a day, are in such ISDN DSL combo ports continue only if the client and server support the resumption of broken downloads (resume).

With the launch of All-IP technology, the forced separation but (regarding dropped calls, including emergency calls) for the addition has come VoIP telephony hindrance was so Telekom daily divide in their current terms and conditions only for standard and universal connections lists (Section 2.3.2).

The DSL synchronization remains unchanged, only the Internet connection was so far off temporarily. The disabled the Telephony service with All-IP connections. Deutsche Telekom has now introduced a software patch to fix the problem. (dz)
