Abstract: 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.

Abstract: An improved sealant pad comprises a rectangular field of viscous sealant supported by a tough flexible film substrate. The substrate and sealant field may have the same dimensions of length and width but generally the substrate will extend beyond the sealant field on at least two opposing sides. One or more of these extending borders of substrate may be advantageously coated with adhesive thereby providing sealant pads with up to four extending flaps of adhesive coated substrate surrounding the sealant field. The sealant pads may be produced in a variety of configurations and are useful for environmentally sealing electrical connections such as are found in wiring harnesses.

Abstract: A single circuit for detecting a synchronization pattern in a serial data stream. Subsequent to detecting the synchronization pattern, the single circuit generates the control signals for converting the serial data to a parallel format and loading the parallel data into a first-in-first-out (FIFO) memory. The single circuit includes a controller arranged to receive the serial data stream. A counter is connected to the controller. When the counter is detecting the synchronization pattern and the synchronization pattern is being received, the counter is incremented. Absent the synchronization pattern being received, the counter is reset to a predetermined starting point. Subsequent to detecting the synchronization pattern, the counter generates a load signal. The single circuit further includes a pulse generator arranged to receive the load signal from the counter and generate a pulse of duration equal to a bit period of the serial data stream.

Abstract: Die plates for forming moisture seals about the junctions of wire harnesses afford improved wire separation and contact between the sealant material in a sealant pad and the wires if the opposed die plates have an elastomeric surface, and the opposed surface of at least one plate is radiused causing the sealant material to separate the wires and flow between and around each wire.

Abstract: A closure for use in providing an environmental seal about a wire junction. The closure comprises a closable shell defining, when closed, an internal wire junction receiving chamber having first and second opposite open ends, for receipt of wires therethrough. The shell comprises first and second shell sections, and an interference fit locking arrangement oriented between the shell sections. In one embodiment, the shell sections are unitary, i.e. they are joined along a hinge line. In an alternate embodiment, the shell sections are independent of one another, but engageable in a nesting manner. The interference locking mechanism preferably comprises a plurality of elongate, continuous, interengageable rachet teeth. In use, sealant material is positioned within the shell sections, and a junction to be sealed is enclosed therein.

Abstract: This circuit is a trunk type interface circuit which interfaces between duplicate copies of an ISDN system and T-carrier facilities. The circuit is controlled by a digital signal processor which has a 16-bit wide data bus. The digital signal processor is capable of supporting various Zero Byte Time Slot Interchange (ZBTSI) techniques. Also included is an administrative microprocessor which collects data concerning the operation of the trunk circuit and transmits this information to the ISDN system. The administrative microprocessor also receives information from currently unused data bits in the input bit stream from the ISDN system. The trunk circuit includes one receiver which collects and stores data transmitted by the ISDN system. Another receiver collects and stores data transmitted via the T-carrier facilities. The trunk circuit also includes two transmitters. One transmitter converts previously formatted data to T-carrier compatible data and transmits the data via the T-carrier facilities.

Abstract: 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.

Abstract: This circuit converts data in an ISDN data format to data in a T-carrier compatible data format and vice versa. The converted data is then stored in a memory for subsequent transmission. Due to the format differences, the data may be discontinuous. This circuit stores the data in memory in a contiguous fashion to promote and to facilitate the subsequent transmission of the data. This circuit includes a timing and control arrangement which indicates the size of each channel and frame of input data. This circuit generates memory addresses for the storage of both ISDN and T-carrier formatted data which are contiguous over multiple frames of data. A counting arrangement of this circuit converts data received in a modulo 32 format to stored data in a modulo 24 format or vice versa. In addition, this circuit provides output signals for generating proper framing bits and extended superframing information.

Abstract: 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.

Abstract: 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.

Abstract: A ringing generator testing arrangement for a digital telephone network is shown comprising a zero crossing detector connected to the ring lead of a line circuit under test. The zero crossing detector gates a clock signal into a counter circuit during the negative to positive transition of the ringing generator signal positive half cycle. The counter circuit advances until the next positive to negative transition of the ringing generator signal. At this time, the zero crossing detector cuts off the clock signal and the counter circuit transmits to a central control complex a count representing a measured interval of the ringing generator positive half cycle.
