摘要： Method of reinitializing dictionaries in a data transmission system using data compression having a transmit device and a receive device, and in which strings of characters have to be transmitted in a compressed form, the transmit device having a transmit dictionary storing codewords associated with the strings of characters which are transmitted instead of the strings of characters, the receive device having a receive dictionary storing codewords associated with the strings of characters, and both dictionaries being updated each time a new string of characters has to be transmitted so that the contents of the dictionaries remain identical. This method saves at least the addresses of the parts of the transmit or receive dictionary which have to be modified by a dictionary updating operation, builds a check message based upon the contents of the transmit dictionary updated by the dictionary updating operation, transmits the check message from the transmit device to the receive device, and then deletes in both dictionaries the parts which are determined by the saved addresses in the event that the check message does not correspond to the contents of the updated receive dictionary. This enables both dictionaries to be reinitialized in an intermediate state without being reset.

摘要： Method of updating dictionaries in a data transmission system wherein strings of characters have to be transmitted in a compressed form from the transmit device to the receive device, the transmit device having a transmit dictionary storing codewords associated with the strings of characters which are transmitted instead of the strings of characters, the receive device having a receive dictionary storing codewords associated with the strings of characters, both dictionaries being updated each time a new string of characters has to be transmitted so that their contents remain identical. This method stores a value into a specific field of the dictionary location in which the codeword associated with each string of characters is stored, this value corresponding to at least one parameter dependent on the string of characters; accesses a plurality of dictionary locations to determine which location has a value in this specific field which is closest to a target value, deletes the contents of the dictionary location containing the closest value, and uses this dictionary location to store the codeword corresponding to the new string of characters.

摘要： In a token ring network a periodic recirculating frame having a plurality of information carrying slots and a header section is used for enabling a plurality of telephone stations to exchange information carrying signals. The header is provided with a token which can assume one of three states. In the first state FF, a telephone station wanting to make a call, changes the token to the second state 00 and inserts call establishment information in the header. A server station also connected in the ring detects the second state as a request to establish a connection from and to a station specified in the header. The server changes the token to the third state AA and inserts a slot assignment in the header. All stations receiving a frame with a token in the third state examine the header. The calling station implies confirmation of the requested connection and the called station is made aware of the call and the identity of the caller. When this frame returns to the server the token state is set to FF and another station on the ring can request a slot for communication with another station.
