The BT Home Hub is a family of wireless residential gateway router modems distributed by BT for use with their own products and services as well as wholesale resellers i.e. LLUs. The latest versions of the Home Hub are based on the Wi-Fi 802.11ac standard, and are also backward compatible with the 802.11b/g/n standards. All models of the Home Hub prior to the Home Hub 3 support VoIP Internet telephony via BT’s Broadband Talk service and are compatible with existing DECT handsets. The BT Home Hub works with the now defunct〔(【引用サイトリンク】 title=BT Fusion on Hub 1.0 )〕 BT Fusion service and works with the BT Vision video on demand service.〔(【引用サイトリンク】 title=BT Vision self install process )〕 The BT Home Hub 1.0, 1.5 and 2.0 devices connect to the Internet using a standard ADSL connection. The BT Home Hub 3 and 4 models support PPPoA for ADSL and PPPoE for VDSL2, in conjunction with an Openreach-provided VDSL2 modem to support BT’s FTTC network (BT Infinity). Since hardware version 5 of the Home Hub was released in August 2013 it includes its own VDSL2 modem for Fibre-optic connections. Firmware is pushed out to the device by BT automatically. ==History== Prior to release of the Home Hub (2004-2005), BT offered a product based on the 2Wire 1800HG, and manufactured by 2Wire. This was described as the "BT Wireless Hub 1800HG", or in some documentation as the "BT Wireless Home Hub 1800". This provided one USB connection, four ethernet ports and Wi-Fi 802.11b or 802.11g wireless connection. A total of ten devices in any combination of these was supported. The hardware contained within the BT Home Hub 1.0 and 1.5 was manufactured by Inventel, and is equivalent to other Inventel produced and third-party branded routers such as the Orange Livebox and the Thomson SpeedTouch 7G and ST790. Consequently, the Home Hub 1.0 can be flashed with some firmware such as that for the 7G; however full functionality cannot be achieved using this method. The Home Hub 1.5 firmware, whilst not hardware locked as previously claimed, does have extra locks in the bootloader which can now be circumvented and full functionality achieved. There are two versions of the BT Home Hub 2.0, the A and the B model. The hardware contained within the Home Hub 2.0A was manufactured by Thomson SpeedTouch, who had bought out Inventel and all their hardware and software rights. This model is electronically identical to the Thomson SpeedTouch TG797n. The hardware contained within the BT Home Hub 2.0B was manufactured by Siemens' Gigaset division in Germany. The middleware was developed by (Jungo ), a subsidiary of NDS, and is based on their openRGTM product. Some Home Hub 2.0 units were also made by Hon Hai Precision Ind. Co. Ltd. In the standard firmwares, telnet shell access is available in earlier versions (up to 6.2.2.6) on the BT Home Hub 1.0 with appropriate user permissions. This is identical to the custom shell used in the SpeedTouch range of routers and provides an almost identical software feature set, with a few notable exceptions (e.g. PPP authentication is locked on the BT firmware). This is not the case in the unlocked versions, as full telnet access is available. There are two versions of the BT Home Hub 3, the A and the B model. The hardware contained within the Home Hub 3A was manufactured by Siemens' Gigaset division (now Sagem) and is based on a Lantiq XWAYTM ARX168 chipset supporting ADSL2+. The Home Hub 3B was manufactured by Huawei and also supports ADSL2+. The Home Hub 3B is powered by a highly integrated Broadcom BCM6361 System-on-a-chip (SoC). The BCM6361 has a 400 MHz dual MIPS32 core processor as well as an integrated DSL Analog Front End (AFE) and line driver, gigabit Ethernet switch controller and 802.11 Wi-Fi transceiver.〔(【引用サイトリンク】 title=BT Home Hub 3.0 - Type B )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BT Home Hub」の詳細全文を読む スポンサード リンク
