Title: Signal processing method for digital subscriber line storing equipment
Inventor: HASHIMOTO MASAO
IPC: H04Q3/545
Filed: 1987-09-22
Abstract: PURPOSE:To handle the respective conditions of an overloading state and a no-load state by stopping the reading of a corresponding signal when the D- channel of a certain specific digital subscriber line enters the overloading state, and performing processing without affecting the D-channel signal reception of other digital subscriber lines. CONSTITUTION:A CPU 50 reads D-channel reception display signals (RD1-RDn) from D-channel terminating circuits DH 31-3n out of a D-channel reception display readout port (IO) 40 periodically and processes it. The CPU 50 counts signals which are read out and processed periodically in LN units, judges that a LN is overloaded when its counted value exceeds a set threshold value, and stops the D-channel signal reception of the LD in the overloading state without affecting the delay of the reception processing of other LNs. Consequently, the delay time of D-channel signal reception processing from other digital subscriber lines caused by a lot of D-channel signals of one digital subscriber line can be shortened.

Title: Telephone set
Inventor: AOYANAGI KATSUMI
IPC: H04M1/00
Filed: 1993-09-27
Abstract: PURPOSE:To prevent noise caused at muting of an amplifier from being heard by muting the amplifier as soon as a period of ringing an n-th frame signal tone is finished so as to overlap the end of the signal tone and the noise sent from a speaker with each other. CONSTITUTION:Let a busy tone generating period be T1 and a busy tone stop period be T2 and both the periods form one frame. The frames are made up of 1st, 2nd,... n-th frame, and as soon as the busy tone generating period T1 at the n-th frame is finished, a CPU 7 applies muting to an amplifier 8 for generating a signal tone by mute control to terminate its operation. Since the amplifier 8 is muted as soon as the period T2 of ringing the signal tone of the n-th frame is finished by controlling the timing of muting in this way, a noise sound (popping noise) caused when the amplifier 8 is muted is not heard by the operator by overlapping the end of the signal tone and the sound noise generated from the speaker 9.
