Patent CA-2259071-A1 (CA)
Inventor: HARADA RYOICHI
IPC: G10L19/012
Filed: 1999-01-12
Abstract: A voice encoding/decoding apparatus includes a voice encoding unit and a voice decoding unit. In the voice encoding unit, a non-voice signal detector detects whether an input signal is a voice signal or a non-voice signal and outputs a signal identification signal on the basis of the detection result. When the non-voice signal detector detects a voice signal, a voice encoder encodes the input signal as the voice signal and transmits encoded data to the voice decoding unit. When the non-voice signal detector detects a non-voice signal, the voice encoding unit transmits the input signal to the voice decoding unit as non-encoded transmission data.      The voice decoding unit includes a voice decoder and a first switch. When the non-voice signal detector detects the voice signal, the voice decoder decodes the encoded data transmitted from the voice encoder and outputs the decoded voice signal. The first switch selects, on the basis of the signal identification signal output from the non-voice signal detector, the decoded voice signal or the non-encoded transmission data.

Patent CA-2266004-A1 (CA)
Inventor: PALMSKOG GOERAN
IPC: G02B6/12
Filed: 1997-09-11
Abstract: The optoelectrical components which up to now have been used in the fibreoptical region have had waveguides of quartz and glass with hermetic encapsulating, which components have had too high manufacturing costs for profitable use. Through making polymeric single mode (SM) waveguides from plastic, for example, benzocyclobutene polymer (BCB) a simple reliable and inexpensive concept for making waveguides can be obtained. Two of the commercially available grades of BCB/DOW Chemicals have furthermore a refractive index difference which permits manufacturing of buried waveguides with SM characteristics. These two types of BCB material have shown themselves to be especially usable for manufacturing of so-called buried SM waveguides: a heat curable grade (1, 4) used for uder- and over-cladding for waveguides and a photo-definable derivative (3) used as the waveguide material. Encapsulating of a waveguide chip can in this way be made with plastics, at the same time as the connector interface can be formed in the end surfaces of the components.

Patent CA-2271150-A1 (CA)
Title: Rating process and circuitry for communication networks
Inventor: SCHOENBORN FRANZ
IPC: H04Q3/00
Filed: 1997-09-11
Abstract: A dynamic call charging system is presented which is applicable to digitized and analog communications networks. The dynamic call charging procedure or system is based on the load carried by the network at the time the call attempt is made. The loads are continuously measured on all lines above the subscriber line level, for instance, with the aid of load test groups (11). The load test groups consist of a traffic measurement unit (2, 2') connected to the trunks or circuit groups (8) and a charge precalculator (12, 12') which dynamically determines the tariff weight, passing it on to the corresponding exchange at a higher level of the hierarchy. The charge payable for a particular call is indicated to the calling subscriber. After the customer has dialed the last digit of the trunk code, the charge computer (1) calculates the currently applicable charge as a function of the result of the latest measurement of the traffic flowing to that destination, transmitting the computed charge to the calling subscriber's terminal to be displayed there. Now the system assumes an "offer-making" status which is maintained for a certain time. Once a decision has been taken by the calling subscriber, the dialing process is discontinued or, after the input of the number of the person called, the charge displayed is used for calculating the amount payable for the call.  After completion of the call, the charge payable is displayed for the calling subscriber or also for the called subscriber if both customers share the cost. In digital networks, dynamic call charging is both suitable for voice communications and any other type of electronic communications such as data and video transmissions.
