Abstract: ABSTRACT OF THE DISCLOSURE              In the ATM switching system, an ATM speech path is divided into a plurality of functional blocks.  A routing function for distributing cells (packets) each of a fixed length to addresses outgoing lines and a logical multiplexing function are imparted to a switch, while other functions associated with a line typified by a phase synchronizing function and a flow control function are incorporated en bloc in ATM line terminating units and functions capable of being processed by hardware in common to the lines are assembled in a line common unit.  The ATM line terminating unit physically terminates transmission lines and performs the processing relevant to header information of the cells each of a fixed length (ATM terminating processing) and includes a cell phase synchronizing circuit for matching the temporal positions of the cells among the lines and a flow control circuit for avoiding overload exceeding the load declared by subscriber terminal.  The line common unit serves for processings of call control signals and the calls and includes a signal processing circuit and a control circuit.  The switch performs cell multiplexing and switching and is constituted by a self-routing switch.

Abstract: The present invention relates to methods which utilize anti-idiotypic antibodies, or fragments thereof, for tumor immunotherapy or immunoprophylaxis. Monoclonal anti-idiotypic antibodies which recognize an idiotype present on a second antibody or on a T lymphocyte or on an immune suppressor factor which is directed against a defined tumor antigen, can be used for immunization against a tumor, for immune anti-tumor activation or inhibition of suppression, or for in vitro activation of lymphocytes to be used in adoptive immunotherapy. The anti-idiotypic antibodies, or fragments thereof, can also be used to monitor anti-antibody induction in patients undergoing passive immunization to a tumor antigen by administration of anti-tumor antibody. In another embodiment, administration of T lymphocytes which express an idiotype directed against a defined tumor antigen can be used to transfer delayed-type hypersensitivity to the tumor. In another method of the invention, the induction of anti-idiotypic antibodies in vivo by administration of anti-tumor antibody or immune cells or factors exhibiting an anti-tumor idiotype can be therapeutically valuable.
