    Abstract: A system and a methodology to improve the end-user quality of service both in terms of response time and reliability for the transport of in-call DTMF signals in wireless systems, particularly in geostationary mobile satellite systems. The methodology encompasses several techniques to provide acceptable end-to-end quality of service for DTMF. A technique is applicable for transport of DTMF in the wireless subscriber to network direction, where DTMF digits are carried in the form of an out-band message. The central part of the technique is to allow multiple key presses in the same message, thereby increasing efficiency and throughput in long-delay environment. Another technique utilizes the vocoder's functionality to carry DTMF in-band, thereby reducing system complexity. The scheme makes the use of an integrated DTMF detector which can classify a given frame of signal into several classes so that the DTMF encoded packet can carry a unique pattern across the air-interface to the voice decoder at AT, which is capable of identifying the pattern. Another technique pertains to the use of a message based DTMF transport between two ATs on a separate logical channel with a unique Service Access Point Identifier (SAPI) providing guaranteed service for DTMF transport in an AT-AT call.

    Abstract: The system for testing ADSL DMT transmission circuits includes means for applying fewer tones than all of the tones in a DMT spectrum to a unit under test and means for comparing the signal level of a noise signal in a missing tone region of a measurement spectrum to the signal level of at least one other tone that is present in the measurement spectrum. Thus, the system can complete circuit testing in the range of several to tens of seconds of test time and enables rates wich are compatible with beat rate requirements for production testing of ADSL circuits.

    Abstract: A decimating time discrete filter comprises transform means (2) for transforming a real valued input signal (i) into a complex signal (u) represented by its real part Re{u} and its imaginary part Im{u}. The output signal (u) is down sampled by means of a decimator (4) which reduces the sample frequency by a factor of 2. Due to the downsampling process, a desired tone input signal can be translated to a different frequency. In order to prevent interference from signals at the input having the same frequency the desired input signal, in the prior art filter a Hilbert transformer (Fig. 2,8,b) is used as transform means (2). In the filter according to the invention, the transform means (2) have a transfer function with a increased width transition band from the frequency of the desired input signal to the frequency to which said input frequency is converted.

    Abstract: A voice communication controller 100 (e.g., private branch exchange (PBX) ) is described herein which can automatically enable an outbound dual tone multi- frequency (DTMF) feature for one of it' s extensions 102 while participating in a session with an external DTMF communication system (e.g., a conference/collaboration bridge 114a, an interactive voice response (IVR) system 114b, or a voice mail system 114c). This is desirable because if the user 106 presses button (s) on their phone 104 then the voice communication controller 100 which has enabled the outbound DTMF feature will not attempt to ' process the corresponding DTMF digit (s) but instead will automatically transfer the corresponding DTMF signal (s) to the external DTMF communication system 114a, 114b, 114c. Specifies that a presence server is used to determine whether DTMF should, be activated or not, however not presence information is used. Simply the dialled telephone number is analysed to determine the activation of the DTMF or not.
