Abstract: The present invention belongs to the field of flame arresters, and discloses a buffered wall flow multi-channels flame arrester. The flame arrester comprises a buffering and splitting cover and a Z-type wall flow multi-channels flame arresting core, wherein the buffering and splitting cover has a round-bottom plain-top cylindrical shape or hemispherical shape, with pinholes distributed in the cover surface, and channels are arranged inside the Z-type wall flow multi-channels flame arresting core. In every two adjacent channels, the inlet of one channel is blocked, and the outlet of the other channel is blocked, and in the height direction in the central cross section of the flame arresting core, pinholes are arranged in the wall surfaces between adjacent channels, and adjacent upper and lower channels constitute a fluid channel.

Abstract: Disclosed is a fax control method, including: presetting a preprocessing configuration policy for preprocessing a fax signal in a gateway device, herein the preprocessing configuration policy contains a configuration policy of a fax control parameter that affects a success rate; and the gateway device acquiring a fax parameter negotiation signal in a fax process, reconfiguring the fax parameter negotiation signal according to the preset preprocessing configuration policy, and then sending the reconfigured fax parameter negotiation signal to a corresponding fax machine.

Abstract: A method for a home gateway to realize an Interactive Voice Response (IVR) service and a home gateway are provided. The method includes that: when a voice user belonging to a home gateway serves as a called user, the home gateway provides an IVR prompt to a calling user, so that the calling user makes an IVR service request according to the IVR prompt; and the home gateway receives the IVR service request, and performs an IVR service operation corresponding to the IVR service request. The present disclosure satisfies multi-level service requirements of a home user.

Abstract: A control method of an intelligent home terminal and an intelligent home terminal are provided. In the method, voice information input by a user is received; it is judged whether the voice information is a preset voice instruction; when the voice information is judged to be the preset voice instruction, the voice instruction is converted into a control command, and a related operation is executed according to the control command.
