Filed:

Jan 25, 1988

Appl. No.:

7/148331

Inventors:

Steve M. Lin - East Brunswick NJ
Joseph F. Rizzo - Lincroft NJ

Assignee:

Bell Communications Research, Inc. - Livingston NJ

International Classification:

H04M 350
H04Q 342

US Classification:

379 67

Abstract:

Enhanced telephone services are provided through a multi-service telephone switching system that contains a programmable adjunct connected to a telephone switching system. Specifically, this system includes a telephone switch that serves at least one subscriber and an adjunct connected both through one or more distinct paths, such as a number of hunt group lines, and through a datalink, such as a simplified message desk datalink, to the telephone switch. The telephone switch routes a telephone call involving this subscriber to the adjunct through an available hunt group line and provides a message to the adjunct over the datalink specifying a condition under which the call was routed. In response to this message, the adjunct takes complete control of the call substantially throughout the remainder of its duration and provides a desired enhanced service that has been pre-defined by a service script stored within the adjunct. Different service scripts can be invoked to provide correspondingly different enhanced services to the subscriber depending upon the specific condition for which the call was routed to the adjunct and/or a specific event occurring during the call.

Appl. No.:

6/064042

Inventors:

Joseph F. Rizzo - Lodi NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H04B 158

US Classification:

179170D

Abstract:

Transhybrid loss is maximized in a transmission network (FIG. 1, 101) of the type for coupling a bidirectional transmission facility (102, 2-wire) to receive (103) and transmit (104) unidirectional transmission facilities (4-wire) by automatically adjusting impedance elements (RKL and RZL) of an impedance network (202, FIG. 3) to obtain an optimum match to the impedance of the bidirectional facility (102). To this end, a plurality of tones (107) are individually supplied to a receive port (111) of the transmission network (101) and the impedance elements (RKL and RZL) are controllably adjusted in a prescribed sequence (FIGS. 7-10) to obtain amplitude nulls at a transmit port (112) of the transmission network (101). Then, an additional signal having a plurality of predetermined frequency components which repeat periodically is supplied to the receive port (111) and a predetermined one of the impedance elements (RKL) is again adjusted to obtain an average value amplitude null at the transmit port (112). In one embodiment of the invention, the additional signal is a pseudo-random noise signal having frequency components at a fixed spacing in a predetermined frequency band.

International Classification:

US Classification:

1791702

Abstract:

"Transhybrid" loss is maximized in a transmission network of the active canceler type employed to couple receive and transmit unidirectional transmission paths to a bidirectional transmission path including 2-wire loaded type cable by controllably adjusting impedance elements of the canceler circuit in a prescribed sequence including adjustment of a network build out capacitor to obtain amplitude nulls of signals detected on the transmit path while supplying individual ones of a plurality of test signals to the receive path. The test signals include first and second signals having a plurality of equally spaced frequency components in first and second frequency bands, respectively, and a third signal having a predetermined single frequency. The adjustment sequence includes a plurality of iterative adjustments of predetermined impedance elements in predetermined groups until no changes in the impedance settings occur and multiple iterative adjustment of predetermined groups until no changes in the impedance settings occur. The impedance elements to be adjusted and the adjustment sequence are selected to rapidly converge the canceler circuit to an optimum transfer function for generating a correction signal which is substantially a replica of an error signal to be canceled from the transmit path.

US Classification:

Abstract:

"Transhybrid" loss is maximized in a transmission network of the active canceler type employed to couple receive and transmit unidirectional transmission paths to a bidirectional transmission path including 2-wire nonloaded type cable by controllably adjusting impedance elements of the canceler circuit in a prescribed sequence to obtain amplitude nulls of signals detected on the transmit path while supplying individual ones of a plurality of single frequency test signals to the receive path. The adjustment sequence comprises a first procedure including a plurality of iterative adjustments of predetermined impedance elements in predetermined groups until no changes in the impedance settings occur and multiple iterative adjustment of predetermined groups until no changes in the impedance settings occur. If frequencies become equal at which poles and zeros occur associated with predetermined ones of the impedance elements, the impedance values of those elements are fixed in prescribed relationship and a second procedure is employed to adjust others of the canceler elements. The impedance elements to be adjusted and the adjustment sequence are selected to rapidly converge the canceler circuit to an optimum transfer function for generating a correction signal which is substantially a replica of an error signal to be canceled from the transmit path.

International Classification:

Abstract:

Transhybrid loss is maximized in a transmission network (FIG. 1, 101) of the type for coupling a bidirectional transmission facility (102, 2-wire) to receive (103) and transmit (104) unidirectional transmission facilities (4-wire) by automatically adjusting impedance elements (RKN, RZN, etc. ) of an impedance network (202, FIG. 3, FIG. 4) to obtain an optimum match to the impedance of the bidirectional facility (102). To this end, individual ones of a plurality of tones (107) are supplied to a receive port (111) of the transmission network (101) and the impedance elements (RKN, RZN, etc. ) are controllably adjusted in a prescribed sequence (FIGS. 8-16) to obtain amplitude nulls at a transmit port (112) of the transmission network (101). In one embodiment, predetermined ones of the impedance adjustments (RKN, RZN, etc. , 820-823, 828-831) are iterated with predetermined ones of the tone signals being supplied to the receive port (111) further to optimize the impedance match.

International Classification:

H04B 320

US Classification:

1791702

Abstract:

A bidirectional transmission path is typically coupled to unidirectional receive and transmit paths to effect amplification in repeaters or the like. A determination of whether the bidirectional path includes either loaded or nonloaded type 2-wire cable is made by inserting a test signal having a predetermined frequency and a predetermined amplitude into the receive path and measuring the peak amplitude of a transmit signal developed on the transmit path. If the transmit signal peak amplitude is greater than a predetermined threshold value, the 2-wire cable is considered loaded type, and if the transmit signal peak amplitude is less than the threshold value, the 2-wire cable is considered nonloaded type.
