Title: Generalized arrangement for routing telecommunications calls
Inventor: FREY ALAN EUGENE
IPC: H04Q3/00
Filed: 1999-08-31
Abstract: Apparatus and a method for controlling the establishment of telecom-munications calls. In response to a service request from a calling party, a switch serving the calling party transmits a query identifying the called party to a shared database. The database provides information identifying the switch for accessing the called party, and information for identifying port(s) for accessing the called party from that switch. When a customer moves from one location to another, the database is updated to reflect the switch and port identification associated with the new location of the customer.      If the called customer is a mobile customer, the database maintains information concerning the current location of that customer so that calls can be immediately switched to that customer. Advantageously, a single database for storing information about the location and class of service of all customers served by a network greatly simplifies the process of routing calls, allows for great flexibility in numbering plans, and greatly simplifies the process of providing service to a customer who has moved.

Patent CA-2299017-A1 (CA)
Inventor: WILCOXSON DONALD C
IPC: H04L1/00
Filed: 2000-02-18
Abstract: A digital data communication system is provided for transmitting a high speed differentially encoded data signal between a transmitter and a receiver. On the transmitter side (44), a high speed input data stream (42) is separated into a plurality of lower rate data streams by a demultiplexer (46). Prior to being multiplexed together to form a single high speed data stream, each of the lower rate data streams are individually block encoded by a group of Reed-Solomon block encoders (48) and then differentially encoded by a group of differential encoders (50). Alternatively, the plurality of low rate data streams are block encoded and then multiplexed together prior to being differentially encoded, so long as the multiplexing is performed on a code symbol-by-code symbol basis.    Since the performance of a non-binary-based block code is based on an input code symbol error rate (as opposed to an input bit error rate), performance loss associated with either of the differential encoding schemes of the present invention are comparable to a non-differential encoding scheme.

IPC: G06F12/00
Filed: 2000-11-30
Abstract: A memory controller controls a buffer which stores the most recently used addresses and associated data, but the data stored in the buffer is only a portion of a row of data (termed row head data) stored in main memory. In a memory access initiated by the CPU, both the buffer and main memory are accessed simultaneously. If the buffer contains the address requested, the buffer immediately begins to provide the associated row head data in a burst to the cache memory.      Meanwhile, the same row address is activated in the main memory bank corresponding to the requested address found in the buffer. After the buffer provides the row head data, the remainder of the burst of requested data is provided by the main memory to the CPU.
