Abstract: The invention relates to a codec circuit for increasing the data transmission rate in a modem transmission. Said circuit comprises a first programmable digital filter (13) which is connected in a first transmitted signal path of the codec circuit, a second programmable digital filter (22) which is connected in a received signal path of the codec circuit and a modem signal identification unit (31) for identifying whether the transmitted signal, emitted in the transmitted signal path or whether the received signal, received in the received signal path is a modem signal. If a modem signal is identified, the modem signal identification unit (31) switches the first and second digital filters (13, 22) onto a broader filter bandwidth.

Abstract: The invention relates to a method for transmitting data between an analog modem (3) and a remote data terminal (4). The data can be transmitted at a variable sampling rate >/= 8 kHz by means of a PCM modulation method from the analog modem (3) to a subscriber line module (5) that is provided with a coder/decoder device (50) with a corresponding sampling rate via an analog data transmission line (1). From the subscriber line module (5) at least two data transmission links K1, K2,..., Kn to the remote data terminal (4) can be established in parallel. The data transmission capacity properties of the data transmission line (1) during establishment of the link are determined. The maximally possible number mmax of data symbols Sxy that can be transmitted per data transmission link K1, K2,..., Kn is determined. A certain number n of switched data transmission links K1, K2,..., Kn required for a predetermined data transmission rate is established on the basis of the data transmission capacity properties and the determined maximally possible number of transmittable data symbols Sxy per data transmission link K1, K2,..., Kn for producing a data transmission rate between the analog modem (3) and the remote data terminal (4) that is higher than 64 kbit/s.

Abstract: The invention relates to a method for transmitting data from a data source to a data sink in a digital terminal via a data line, within a communications time slot of a time multiplex system. A predetermined no-load data item applied to the data line indicates a no-load state in which no data is transmitted. The inventive method comprises the following steps: transmitting a transmit data item to be transmitted from the data source to the data sink via the data line if said transmit data item does not correspond to the no-load data item, or logically combining the transmit data item with a combination data item to form a representation data item if the transmit data item does correspond with the no-load data item; and then transmitting an indicator data item and the representation data item from the data source to the data sink, in succession; temporarily storing a receive data item applied to the data line in the data sink for data processing if the receive data item is not identical to the indicator data item or inversely logically combining the representation data item following the receive data item with the combination data item to form the original transmit data item if the receive data item is identical to the indicator data item and temporarily storing the transmit data item formed from the representation data item by inverse combination for further data processing in the data sink.

Abstract: The invention generally relates to a modem connected via a digital interface to a switched public telephone network and to a method for probing the line properties. The modem communicates with a second modem also connected via a digital interface to the same switched public telephone network. The public telephone network may incorporate voice compression devices (ADPCM G.726, G.723 etc.), digital pads (digital attenuators), robbed bit signalling and echo cancelling devices. The probing sequence of the invention uses large amplitude changes in a symbol sequence (each symbol having a duration of 125 mu s). After that single amplitude change, the signal may return to the previous value or continue with the new amplitude value for a number of symbols. The number of symbols is selected to be larger than any expected impulse response of a digital impairment of the channel. The amplitude value change must be large enough to produce a sufficient result in the presence of digital pads with or without the presence of RBS.

Abstract: An So-interface for an ISDN basic access for connecting a four-wire line with a pair of receiver wires and a pair of transmitter wires to an ISDN terminal, while separating their potentials, has a capacitor (C1, C2) in each receiver wire (SR1, SR2) and a transformer (T) in each sending wire (SX1, SX2) to separate their potentials. Inductors (L1, L2, L3, L4) are connected to each receiver wire (SR1, SR2) and transmitter wire (SX1, SX2) on the interface side. The pair of receiver wires (SR1, SR2) is preferably connected on the terminal side to a voltage amplifier (OP) whose voltage amplification ratio is the same as that of the transformer (T) in the pair of transmitter wires (SX1, SX2).
