Abstract

DC60 (27/04/41) The collective modulator pool (pool) layout is provided with consent. Allows the user to pre-set and personalize the rooting parameter settings. Echo signal for any collective echo suppressor on a known basis The peculiarities of the echo trajectory of the specific transmission path are preceded by which will be used. For the calling that follows Suppressor with independently set parameter settings It is then switched to that route during the duration of the call, for example, at the call preparation, when the telephone line route is identified as being used to complete the call, a "flag". ("flags") are also brought back in connection with a specific path. That "flag" identifies the specific echo-suppressor parameters that will be used for that route. Has been packed into the resulting silencer device Picked from that public And that device was switched to the specific telephone line involved. The switcher was able to optimize the elimination of the echo in the system and improve the voice quality. Significantly up overall The collective structure (pool) of the reflector has been provided with consent. Allows the user to pre-set and personalize the rooting parameter settings. Echo signal for any reflector In general, on the basis of knowing The peculiarities of the echo trajectory of the specific transmission path are preceded by which will be used. For the subsequent bangs Suppressor with independently set parameter settings It is then switched to that path during the duration of the call, for example, at call arrangements when the telephone line route has been identified as being used to complete the call. Done. The "flag" ("flag") has also been brought back with respect to a specific path. That "flag" identifies the specific echo suppressor setting that was used for that path. Those parameter settings are packed into the resulting resonator device. Picked from that public And that device was switched to the specific telephone line involved. The switcher was able to optimize the elimination of the echo in the system and improve the voice quality. Significantly up overall
