Abstract

DC60 (27/04/41) The eliminator's pool layout has been provided with consent. Allows the user to pre-define and customize the rooting parameter settings. Reflection for any echo eliminator as a whole, on the basis of knowing. The reflected trajectory characteristic of a particular transmission path exists before which it will be used. for subsequent calls An echo eliminator with independently defined parameter settings. Therefore, it is switched to that route for the duration of the call, for example, at the initialization of the call. When the telephone line has been identified, it is used to complete the call "flag". The "flag" is also returned in connection with a specific path. The "flag" uniquely identifies the specific echo deterrent parameter settings that will be used for that path. has been incorporated into the reflector device. be chosen from the aforementioned community. and the device is switched to the relevant dedicated telephone line. Thus, the switcher can optimize system echo cancellation and improve speech quality. increased significantly overall The eliminator pool layout has been provided with consent. Allows the user to pre-define and customize the rooting parameter settings. Reflection for which echo suppressor? in general on the basis of knowing The reflected trajectory characteristic of a particular transmission path exists before which it will be used. for subsequent smoothing An echo eliminator with independently defined parameter settings. Therefore, it has been switched to that route for the duration of the call, for example at the preparation of the call. When finished, "flags" ("flags") are also returned with respect to a particular path. That "flag" uniquely identifies the specific echo deterrent parameter setting that has been used for that path. Setting those parameters has been enclosed in the eliminator device. be chosen from the aforementioned community. and the device is switched to the relevant dedicated telephone line. Thus, the switcher can optimize system echo cancellation and improve speech quality. increased significantly overall
