摘要： An echo cancellation arrangement is provided for decreasing the "singing" of a connection of a large number of telephone subscribers in a conference calling arrangement. This arrangement includes a means for inserting quiet code during time when the voice samples of incoming PCM data are zero or below a predetermined minimum threshold level. This helps decrease the amount of feedback which is amplified and output through the codec/filter to the listeners through the PCM network. An attenuation arrangement is also included which decreases the level of a summed signal of a summing node of the conference circuit. This sum signal is the combination of each of the conferees' speech. Attenuation of this signal prohibits excessive coupling of amplified feedback to each of the listening conferees.

摘要： An Integrated Services Digital Network module includes a time division multiplexed switching network. Subscribers are connected to the time division multiplex network via a number of facility interface cards. These facility interface cards provide for two wire subscriber connection, four wire subscriber connection, T1 line connection and for three port conferencing arrangements. Originating and terminating multiplexers connect the facility interface cards to the time switching network. Another subsystem provides protocol interfaces for HDLC channels. Another subsystem provides interface to central office switching systems. Lastly, a general purpose computer and file computer system provide for the storage of database and form maintenance functions. Each subsystem is controlled via processor which is linked with each of the other processors by an ethernet local area network. This system provides both Primary Rate (23B+D) and Basic Rate (2B+D) interfaces to the subscribers.

摘要： A wire connector having a conductive barrel with a solder disc disposed in the barrel with wire retaining means to hold the wires in place during heating and melting of the solder disc to form a permanent connection. A shrinkable sleeve, provided with means of sealing, formed around the barrel and extending beyond the ends of the barrel is also shrunk down onto the wires to seal and insulate the connection and hold the wires.

摘要： The present invention is an interconnection of a loop analysis test system (LATS) to a digital switching system. This arrangement includes the utilization of existing network units to establish a path connection from the computer of a LATS system to a measuring unit of the LATS system. This path through the digital switching system provides for the appropriate signaling requirements in order to simulate a telephone call to the digital switching system for connection to a subscriber. Another path is provided to connect the measuring unit to the subscriber line to be tested via a special access network. In addition, this arrangement includes a data base in the CPU switching system to provide for determining whether the connection of this path through the switching system is for a test access or for normal calling functions. The data base also records the interconnection of equipment such that the proper subscriber's line may be accessed when called by the LATS system.

摘要： A data adapter for simultaneously providing a low speed channel, a first high speed data channel, and a second high speed channel over a two wire connection; the two wire connection connects the data adapter to a telephone system. The data adapter includes a line transceiver connected to the two-wire connection, the line interface provides a full duplex transmission link with the telephone system over the two-wire connection. A telephone interface converts data between the first high speed channel and a telephone instrument. A rate adapter converts data between the second high speed channel and a data processing equipment. A protocol controller performs a packet protocol on the low speed channel, and routes the first high speed channel to the telephone interface and the second high speed channel to the rate adapter. A processor that receives and transmits messages through the protocol controller over the low speed channel to the telephone system, and in response to information received over the low speed channel, alternatively information received from the rate adapter, the processor controls the data adapter.

摘要： A digitally activated ringing circuit for use in conjunction with a central processing unit of an electronic telephone central office is connected between the central processing unit and a telephone subscriber via the central office switching network. The ringing circuit generates an analog signal representing a particular one of a plurality of possible ringing frequencies to be applied to the subscriber line. The instantaneous values of the ringing signal are approximated by information contained within a read only memory.
