  • Patent number: 7031462
    Abstract: In an electronic inductor circuit, an operational amplifier drives the base of the electronic inductor transistor, and receives negative feedback from the emitter of the transistor. The transistor and operational amplifier combine to form a voltage-controlled, current source (VCCS) with respect to the loop current. A voltage divider connected across the rectified Tip and Ring voltage (or another node of the circuit at an equivalent voltage) provides a DC reference to the positive input of the operational amplifier, so that the line current automatically increases with an increase in line voltage. A capacitor couples the transmit signal driver to the positive input of the operational amplifier. This electronic inductor circuit can be driven using a low voltage supply and provides sufficient linearity for high-speed modem applications.

The on-hold activity selection apparatus detects the occurrence of an on-hold condition in a communication between a first party terminal and a second party terminal. In response to detecting the on-hold condition, the on-hold activity selection apparatus provides a menu of available on-hold activities to the terminal which is placed on-hold. If a reply is received from the on-hold terminal identifying a selected on-hold activity, the on-hold activity selection apparatus then provides the on-hold terminal with the selected activity. The menu of available on-hold activities may be based on profile information, corresponding to the on-hold terminal, stored in a database.

  • Patent number: 6219415
    Abstract: The call hold state notification system functions to provide an indication to the parties presently served by the existing call connection that the original hold state has been terminated. This is accomplished by enabling both parties (multiple parties on a n-way call) to a call connection to place their respective call termination on hold to serve another call or to perform some other task without having to physically monitor the call connection. When any party to the call connection removes the hold state at their respective telephone station set, the remaining parties to the call connection who have a hold state active at their termination receive a notification of the reconnection of the party to the call connection. Optionally, the returning party also receives a notification that the call connection is in an on hold state at the other end of the call connection and that party is being advised of the termination of the held state by the returning party.

  • Patent number: 6201865
    Abstract: A digital direct access arrangement (DAA) circuitry may be used to terminate the telephone connections at the user's end that provides a communication path for signals to and from the phone lines. Briefly described, the DAA provides a programmable means for the DC termination for a variety of international phone standards. The invention may also be utilized with means for transmitting and receiving a signal across a capacitive isolation barrier. More particularly, a DC holding circuit is provided that has switchable time constants. A first time constant may be utilized during a first operation phase immediately after off-hook conditions to allow for fast settling times. Then, a second operation phase is entered in which a second time constant may be utilized. During the second operation phase the DC holding circuit operates slower to create improved low frequency performance.

  • Patent number: 6122346
    Abstract: A telephone on-hold system (10) allows a calling party such as a consumer (20) to place the telephone call on-hold from the consumer's handset (18C) in response to dialing a number where the receiving end (R) put the call on-hold pending availability of an agent (22). While the call is on-hold from the consumer's end, a counter-message is played to alert the agent (22) to notify the consumer's handset (18C) that the agent (22) is available, such as by depressing touch-tone keys at the agent's end (18R). The system (10) recognizes the tones and provides an alert (40) to the consumer (20) so as to allow the consumer (20) to end the on-hold status of the call from the consumer's end and undertake normal conversation with the agent (22).

  • Patent number: 5875231
    Abstract: An on hold telephony service that allows a party placed on hold, if he is a subscriber to the service, to also place the call on hold and then hang up. The on hold service can be implemented on a central office switch or an enhanced services platform connected to the switch. The on hold service is accessed by the party placed on hold, i.e., subscriber, through a transfer function that causes the call to be maintained by the on hold service. When the party who originally placed the call on hold returns to the call, the on hold service informs him that the service will then call the subscriber so that both parties can be reconnected.
