AVM FRITZ! Card DSL in the test: ADSL and ISDN with one card

The hardware

After we have dealt with the software, we now come to the hardware, the FRITZ! Card DSL. The 32-bit PCI 2.2 card is the first DSL terminal device that has passed the qualification from the CETECOM ICT Services test institute as a U-R2 terminal device. The U-R2 standard is based on the international ITU standard G.992.1, Annex B, more on this later. Of course, we also asked ourselves how we can 'bench' the performance of this card? The speed of downloading or uploading is certainly important, but for online gamers what is more important is what ping value can be achieved. Ping describes the period of time that a data packet needs from one computer to another. The smaller this value, the faster your own (mouse or keyboard) reaction to the course of the game on the server. Here in particular, Telekom is repeatedly attacked due to its relatively high ping values. Telekom uses the 'interleaving' method for DSL data traffic, which guarantees a higher level of security for the data packets, but this increases the ping values. Other DSL providers offer the 'Fastpath' method, which ensures very small ping values, but it can happen that data packets have to be sent several times. A Telekom DSL connection with 'Interleave' is available at the test location, the DSLAM in the exchange is from ECI. Since the beginning of January, Telekom has been using DSLAMs from ECI based on the new Telekom U-R2 standard for new connections. ThisThe new standard is not an official standard, it is only based on recommendations from an international working group. The FRITZ! Card DSL supports the previous ITU G.992.1 as well as the U-R2 and ITU G.994.1 standards. Operation on existing Telekom DSL connections should therefore not be a problem. Caution is advised when changing provider, as the Telekom modems cannot be used with all other DSL providers. However, QSC and Arcor continue to give away the necessary modems to their customers so that there are no additional costs. A change to the U-R2 standard is not yet planned for these two providers.

The tests themselves include different ones Downloads with GetRight, as this logs both the time of the download and the average download speed achieved. Furthermore, some pages were pinged with VisualRoute 6.0b and the results were recorded graphically. Last but not least, the player test should not be missing, here tests were carried out with Unreal Tournament and the best ping values ​​were noted.

To get a 'real' comparison, the same tests were carried out with the Telekom modem at the test location carried out. This also comes from the manufacturer ECI. The connection between the modem and the PC is handled by a 3Com 3C905C-TX 10/100 MBit network card, which addresses the modem at a speed of 10 MBit.
