Patent CA-2271761-A1 (CA)
Title: Broadband telecommunications system
Inventor: GARDNER MICHAEL JOSEPH
IPC: H04L12/56
Filed: 1997-11-10
Abstract: A telecommunication system that can integrate the capabilities of broadband components with the capabilities of conventional circuit switches. A signalling processor (140) receives and processes a first telecommunications signalling message (160) for the call to provide control and signalling messages (162, 163, 164, 165, 166) that identify the selection and transfer the control messages to the ATM  internetworking multiplexers (110, 112, 114) that accepted the access connection for the call. The multiplexers (110, 112, 114) convert user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages (162-166). An ATM cross connect system (120) operationally connected to the multiplexers (110, 112, 114) routes the ATM cells based on the virtual connection identified in the ATM cells. The narrowband switches (130, 132) provides the service to call based on the telecommunication signaling message.
Patent CA-2277958-A1 (CA)
Inventor: PALNATI PRASASTH R
IPC: H04L12/56
Filed: 1998-11-19
Abstract: In the event no completely assembly packets have been received and scheduled for transmission (102), a partially received packet is selected for cut-through transmission prior to receipt of all cells comprising the packet (108). Transmission of the selected packet is initiated and a timer is started (110). If the timer expires prior to the receipt of an end of packet indication for the packet for which transmission has commenced (112), an end of packet signal is generated (114) and cut-through packet is aborted (116).  In this manner, delays associated with packet reassembly may be avoided and buffer sizes of reassembly buffers may be reduced.
Patent CA-2279704-A1 (CA)
Inventor: HAMPEL KARL GEORG
IPC: H01Q3/32
Filed: 1999-08-04
Abstract: The invention is a mechanically or electro-mechanically driven phase shifter for radio frequencies. It is a device for phase shifting a signal propagating through a transmission fine by moving a conductive construct between an active line and a ground plane of the transmission line. The conductive construct capacitively couples with either the active line and/or the ground plane, forming a capacitive shunt that reflects a significant part of the signal. The remaining portion of the signal is reflected at a terminated end of the transmission line, resulting in substantially no signal loss. The reflectance of the conductive constructs is determined by its capacitance to active line and ground, by its length, and by the step in the field-distribution at the interface between air-suspended and sledge-suspended sections. Design alterations are possible that enhance one or several of these effects, such as capacitance enhancement by dielectric coating of the sledge, any length variation, multiple sledge structures, modifications of the sledge cross-section etc. Further, a restriction to usage of only one sledge is also possible. A common driving mechanism is used when using multiple conductive constructs. The phase shifter is used in conjunction with signal separation circuits that separate incoming and reflected outgoing signals.
