We have U-Verse Internet "Max" VDSL service with a 2Wire 3800HGV-B RG. I'm using an ASUS RT-N16 behind the RG, mostly for QoS and better control of our WLAN. I've got the latest Toastman mod (build 1.28.7501.2) of Tomato firmware on the RT-N16. The QoS "Basic Settings" page for this build includes a new section named "Settings for DSL only". There's a single option in that section, "DSL Overhead Value - ATM Encapsulation Type", with a pull down menu and several values:
DSL Overhead Value - ATM Encapsulation Type:
8-RFC2684/RFC1483 Routed VC-Mux
16-RFC2684/RFC1483 Routed LLC/Snap
24-RFC2684/RFC1483 Bridged VC-Mux
32-RFC2684/RFC1483 Bridged LLC/Snap
Does anyone know if any of these settings apply to AT&T's VDSL-based Internet service? If not, what would the correct setting be? Toastman is usually very responsive to suggestions and could probably add the correct option(s) for VDSL, if we know what they are.
Again, this does not apply to U-verse VDSL but it sounds like it will really improve QoS on regular ADSL. I've added some tags to thei reply that will hopeully get picked up in searches for this info by regular DSL users. Also removed the tags from my orignal post, as they were misleading and incorrectly formatted anyway.
