We are dealing with successor DSL-320T which had beautiful removable rubber feet and a plush box. With the DSL-320B D-LINK reduced its costs and feet one loses, the case is reduced and gets lighter but one gains a button M / A on the rear. For use not need software except a web browser for configuration that proves easy if you put in "bridge" mode behind a router. When connected to the PTT line through the ADSL filter (not supplied) we see that syncs without problems and especially fast on high attenuation lines (> 60dB). His job with a router by is facilitated. However, the "ping" means that DSL-320B are always greater than a few milliseconds old DSL-320T in the same working conditions. This can leave a response time considering 5% less efficient compared to the 320T or other modems as Combo BEWAN but to use it all the same. La ADSL connection of 320B on PTT lines with very low noise margin turns out robust which enables to disconnect / reconnect since an associated router without fear to conduct a of IP addresses brewing or various trials. In addition the new DSL-320B is immunized against external RF interference unlike its 320T ancestor, which is a good point. Tested ORANGE ADSL in bridge mode on XP, VISTA and LINUX has never been found wanting. ADSL statistics page is not easy to reach but its consultation provides detailed information about the maximum sync speed down / up, noise margin, attenuation line and a wealth of info about frames sent and received . This allows you to select the best DSL filter your collection (some old ones are defective, other brand are very good as LEA or BELKIN) along with the best RJ11 cable for the PTT line (try a model with screen style BELKIN ): Before you rail against your ISP consider making this experience, guaranteed astonishment on improved noise margin and thus optimizing the ADSL sync! The tested model incorporates the latest firmware "EU 1.22." A programming error is present: French language configuration internal timestamp does not include January or March, but 2 times the month of February and 2 times the month of April! rare and hilarious. We hope a fix from D-LINK ... After that the price should join him all the votes!
