Patent DE-2951758-A1 (DE)
Title: Error detection system for pulse width modulated data transmission - uses clock pulses to determine permissible and non-permissible code receive periods
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: H04L1/20
Filed: 1979-12-21
Abstract: The error detection method uses a signal frame structure for scanning the incoming signal. According to the frame structure, the pulses in the signal are verified or detected as errors dependent upon whether the pulse leading trailing edge is within a permissible or not permissible time slot. The transmitted signal is in the form where a long pulse is high level and zero is low level. The first received pulse starts the receive equipment scanning clock for verification of the incoming bit stream. All received bits transitions must be in a low level time slot of the receive equip scanning clock. For example, when the clock starts two of the pulses are high and is non-permissible receive time slots, therefore the representation of a shortened first transmitted pulse is detected as an error. All correct length pulses and zeros have leading and trailing pulse edges which coincide with scanning clock zero.

Title: Modified exchange equipment for automatic reverse charging of calls - has microprocessor controlling two consecutive connections enabling automatic reverse call after attainment of specified fee
Inventor: HILLIGES FRIEDRICH
IPC: H04M15/08
Filed: 1980-02-29
Abstract: The possibility exists for a called subscriber after he establishes in the conventional manner who the caller is, to decide whether he wishes to accept the fees for the call. If he chooses this option he asks the calling subscriber to replace the receiver and he does likewise. About two seconds later, the calling party receives the ring signal on an automatic basis and the fees are recorded on the fee counter belonging to the called party's line. This is achieved by equipping the local exchange (A) to which calling subscriber (Tn) belongs with equipment comprising a central identifier (H), temporary storage and number setting units (M1,M2) and a line connection unit for each subscriber (Tn). Output therefrom goes to a couple field (VK). A central processor unit (P) already used for controlling the exchange plant (A) is programmed to perform additional functions, such as storing sequentially the calling number (in store Sp2) and the called number (in store SP1). The called subscriber (Tn) has a number store (Tp), a unit fee counter (Zo) and a command push button (SE). The latter is pressed upon replacement of the receiver which sets in train the automatic dialling of the calling subscriber in the reverse direction. In a modified form, automatic call-back occurs in any case except for the last digit, that last one being sent out conditional on button (SE) being pressed. This speeds up connection recovery and excludes interference.
