Have this equipment bought to replace the unstable and function unspeakably poor box, which I got delivered from Alice / O2 to my VDSL line. The Bridge Mode can be activated by simple placing a tick in the Zyxel. Thus, the device works as a simple modem and enables the connection of any router hintenan. Even the required VLAN tagging can take over the Zyxel, so that older routers that do not provide their own tagging, can be used. Thus, the connection is at the Telekom VDSL nothing in the way. (Use the way a Netgear 3500v2 with Tomato firmware). The VDSL Sync is perfect - always the configured by Telekom maximum possible, rarely including minimal.
