    Abstract: Adjunct apparatus for increasing network transmission capacity provides a low-cost, efficient solution for increasing the network transmission capacity of the existing telephone circuit switched network, while keeping the current network equipment unchanged. A Local Switch Network (LSN) Adjunct (LSNA) and a Tandem/Toll Switch Network (TSN) Adjunct (TSNA) interface with standard network elements, such as switches and cross connect equipment. These network adjuncts, comprising a set of low-bit rate speech coders, a dynamic timeslot manager and other supporting functions, advantageously transmit to and receive from a T1/T3/OC3/E1 trunk. More than one channel of voice is carried on one 64 Kbps DS0 timeslot, while still maintaining the voice at toll quality. A sub-timeslot and sub-timeslot bundling are introduced in the standard T1 or E1 frame where each sub-timeslot is analogous to a single bit of the typical eight bit word to provide more than 24 or 30 voice channels respectively. Inband control information is generated for carrying over a T1 or E1 trunk, for example, for mapping sub-timeslot bundles to channels. Conventional out-of-band signaling is provided via SS-7 or other out-of-band signaling system.

    Abstract: The call reestablishment system functions to provide the user with the ability to replace an existing communication connection with another equivalent communication connection in an automated manner that does not disrupt the existing call and to also provide the user with the ability to create a replacement communication connection using a different common carrier as the billing source. The call reestablishment system is activated when a party on an existing communication connection generates feature activation control signals indicative of the desire to access the call reestablishment system. The serving communication system, in response to receipt of the feature activation control signals, enables the requesting party to input data indicative of the nature of the call reestablishment that is required. The call reestablishment system is responsive to this data for creating a replacement communication connection for the existing communication connection and, once the facilities are in place to enable the calling and called parties to communicate, the call reestablishment system automatically transfers the calling and called parties from the original communication connection to this newly established communication connection in a manner that is transparent to the parties and without loss of any communications.

    Abstract: Providing capability for increasing, decreasing, or changing types of bandwidth associated with a telecommunication call during the call and through out the call path. New messages can allocate or deallocate bandwidth associated with the call at each intervening switching node through out the call path. All switching nodes of a switching system involved with the resulting call consider the call as a single call. The new messages allow adding video capability to a voice call and, at a still later point in time, removing the video capability from the call. The result is convenience to telecommunication users in that the user is able to utilize any type or amount of bandwidth during a multimedia call. Yet, at any given point in time, the user pays only for the bandwidth that is being utilized.

    Abstract: For use with a telephone switching system serving a plurality of stations and having a central processor for generating data messages and a ringing circuit for generating ringing signals to a selected station, method and apparatus are disclosed for sending a data message to a selected station during a silent interval between ringing signals. The apparatus includes a detector and a sender. Responsive to a first ringing signal, the detector generates a status signal representative of the silent interval between ringing signals. During the silent interval, the sender sends to the selected station a frequency shift keyed signal representative of the data message.
