Title: Enhanced integrated rate based available bit rate scheduler
Inventor: DABECKI STEPHEN J
IPC: H04L47/6275
Filed: 1997-10-01
Abstract: An available bit rate scheduler for asynchronous transfer mode communication of a plurality of cells over a communication network in which each cell is characterized by a virtual circuit communication channel  and in which each virtual  circuit  is  characterized by one  or more profiles.  Each profile has a group of sub-profiles, with each  sub-profile  having a unique bandwidth allocation component.   The scheduler incorporates a profile queue buffer for receiving, pairing and storing the profiles and sub-profiles and,  a link list processor coupled to the profile queue buffer to receive the profile, sub-profile pairs.  The link list processor detects null profile, sub-profile pairs in the buffer and, over-write them with a selected one of the virtual circuit profile, sub-profile pairs.  A valid pending register of length p bits, and a memory are coupled to the link list processor.  The memory stores pointers to link lists of virtual circuits associated with each of the profile, sub-profile pairs received by the link list processor.   The pointers comprise, for each of the link lists, a head pointer to a first entry in the link list and a next pointer to a virtual circuit in the link list last associated by the link list processor with one of the profile, sub-profile pairs.
Patent CA-2218629-A1 (CA)
Inventor: LAM CHI K
IPC: H04M3/42
Filed: 1997-10-20
Abstract: A handshake between sending and receiving devices (10) that exchange DTMF signals across a network (14) is accomplished by having the receiving device send a DTMF ready tone (digit) for a prescribed interval following receipt of a call set-up message received after the sending device has initiated a call. Upon receipt of the DTMF ready digit, the sending device sends to the receiving device a data message includes a string of digits of interest prefixed by M header digits. After receiving at least a portion of the data message, the receiving device stops transmitting the ready digit. Once the receiving device has received the entire data message, the receiving device strips the protocol digits (the M header digits and any of the ready digits received due to echo). By analyzing the stripped protocol digits, the quality of the handshake between the receiving and sending devices can be determined.

Title: Method and apparatus for signal strength measurement of supervisory audio tones (sats) in a radio communications system
Inventor: RYDE OMAR
IPC: H04B17/00
Filed: 1996-11-08
Abstract: Methods and systems for measuring signal strength of supervisory audio tones (SATs) in radiocommunication systems are disclosed. Exemplary embodiments describe how such measurements may be performed using digital signal processing techniques, while reducing the amount of computing power, e.g., MIPs, used to accomplish this task. During each measurement interval a large number of SAT signal samples are received. Rather than process a complete measurement interval of received SAT samples, exemplary embodiments rely on a sliding average of samples which include both current and previous blocks of samples. In this way, the SAT signal strength can be reported relatively frequently to the system but without the number of computations that would be required to process all of the SAT signal samples received during a measurement interval.

Title: Method and data system for determination of financial instruments for the use of funding of a loan which is at least partially refinanced during its term to maturity
Inventor: TORNES-HANSEN STIG
IPC: G06Q40/00
Filed: 1997-02-03
Abstract: Method and data processing system for determining the type, the number and the volume of financial instruments for funding of a loan with an interest rate adjustment with an equivalent proceeds to a debtor, the loan being at least partially refinanced during the remaining term to maturity of the loan. In the data processing system, data are loaded, which data indicate the principal of the loan, the term to maturity of the loan, the profile of repayment, and a desired/intended profile of refinancing. Furthermore, data are loaded, which data indicate requirements as to maximum difference in proceeds, maximum difference interest rate, and maximum difference in balance between on the one side the creditor and on the other side the debtor. On the basis of these data as well as a first guess at an interest rate, the volume of a number of financial instruments to be applied for funding of the loan is calculated. The results of the calculations can be applied by the debtor, for instance a financial institution such as a mortgage credit institution, to secure that the loan is funded in such a way that interest rate risks such as imbalance in the payment flow is avoided or minimized. By applying the results of the method according to the invention, the creditor has the possibility of creating a hedge between lending and funding.

Inventor: WEIS BERND
IPC: H04L12/701
Filed: 1999-01-18
Abstract: The goal is to set up a connection between a sending and a selected network element of a digital synchronous telecommunications network without the help of a central management system. The telecommunications network is logically structured based on a hierarchy with at least two multiplex layers based on a protocol that is used in the telecommunications network with each network element being able to access at least a part of the multiplex layers.      Using a broadcast that is being sent by the sending network element to all other network elements, possible paths with free transmission capacity are identified between the sending and the selected network element. To this end, first the most suitable multiplex layer for setting up the connection is selected. Then the broadcast is relayed via existing connections of the suitable multiplex layers, which the respective relaying network element can access.      Then the connection is set up via one of the identified paths.
