The D-Link DSL-321B is, as the name suggests additional suitable only for Annex B terminals, usually these are almost all connected in Germany.
In other European countries, however, Annex A is often used, so you should previously inform about their own connection type with the provider and not blind it going to buy and afterwards, as mentioned in some reviews wondering why that part again not darned with the DSLAM synct, ,
The unit has one for the layman not so readily by looking configuration interface. Art enthusiasts and people involved in the optimization of their DSL stability / speed are interested, I can recommend this modem ideal, the differences have been fully come into their own, it has next to the powerful Broadcom chipset, which compared with some other Far East modems significantly more speed with the same line attenuation offers, also various fine adjustments with respect to the DSL connection.
The scope of equipment falls quite extensive from a prov as a modem device. In addition to Bridge-Mods for use of routers and dial via PC, a client (almost like routers) Configuration of DSL321B with automatic dialing is possible, a DHCP server is also on board.
For customers of smaller providers should also be mentioned that the VPI / VCI, are values which can vary depending on the provider freely adjustable. The modem can therefore be used at each AnnexB connection.
In summary it can be said that I am very satisfied with the device, I have no more Syncverluste.
Here again, a measurement with a DSL 6000 connection: Upload (gross: 869.5 kbit / s, net: 759 kbit / s) Download (gross: 7.14 Mb / s / net 6.26 Mb / s)
The rumor of higher pings due to the stability advantages with the Broadcom chipset used I can not confirm, ping is 14ms to Host Europe, thus become even more comfortable with than with my old Castenet AR801 Modem)
I hope I could help you with my small report.
