摘要： A radio communication system for processing information signals received from telephone trunk lines for transmission over a plurality of RF subscriber channels is disclosed. The system includes a network interface exchange for sampling the received information signals and sequentially combining the resultant plurality of sampled information signals into one or more multiplexed transmit channel bit streams. The network interface exchange includes a processor for assigning a first of the sampled information signals from one of the trunk lines to an available repetitive slot position of a first of the transmit channel bit streams provided to a first destination node associated with the first of the sampled information signals, the first destination node being determined in accordance with subscriber unit identification information received over the trunk line. A transmitter transmits a forward interface signal to the first destination node over a network interface channel in response to the first multiplexed channel bit stream. The system includes a remote telephone exchange, in RF communication with the network interface exchange over the network interface channel, corresponding to the first destination node and located distal from the network interface exchange. The remote telephone exchange extracts the first sampled information signal from the forward interface signal, generates a first subscriber signal, transmits the first subscriber signal over the first RF subscriber channel to a first subscriber unit, and can route reverse link signals from the first subscriber unit to a second destination node independently of the network interface exchange.

摘要： A radio communication system for processing information signals received from telephone trunk lines for transmission over a plurality of RF subscriber channels. The system includes a network interface exchange for sampling the received information signals and for sequentially combining the resulting sampled information signals into a multiplexed transmit channel bit stream, each of the sampled information signals occupying a repetitive slot position in the multiplexed transmit channel bit steam. The network interface exchange further includes a processor for assigning a first of the sampled information signals from one of the trunk lines to the repetitive slot position corresponding to a first of the RF subscriber channels associated with a call request signal received over the one trunk line. A transmitter is provided for transmitting a forward interface signal over a network interface channel in response to the multiplexed channel bit stream. The system further includes a remove telephone exchange, in RF communication with the network interface exchange over the network interface channel, for extracting the first sampled information signal from the forward interface signal. The remote telephone exchange also generates a first subscriber signal on the basis of the extracted first sampled information signal, and transmits the first subscriber signal over the first RF subscriber channel to a first intelligent subscriber unit.

摘要： A fiber optic hub (10) for local area networks (15, 35) and other data communication systems including an internal self-diagnostic and cable test capability for permitting off-line testing of the hub (10) and of fiber optic cables connected to the hub (10). The hub (10) includes a plurality of optical interfaces (30a-30p) each having an optical receiver section (36) and an optical transmitter section (37) and hub-processing circuitry (32) connected to the optical interfaces (30a-30p) for processing data signals received by the optical receiver sections (36) and for providing the processed data signals to the transmitter sections (37) to be transmitted back through the network (15, 35) thereby. Hub (10) further includes a test signal source (61) for generating a test signal to be transmitted from the transmitter sections (36) of one or all of the optical interfaces (30a-30p), and a test signal detector (80) connected to the receiver sections ( 37) of the interfaces (30a-30p) for detecting a test signal received by any of the receiver sections (37) and for generating an error indicator signal when the received test signal differs from the transmitted test signal. The transmitter and receiver sections (36, 37) of any hub optical interface (30a-30p) can be conveniently tested by looping a fiber optic cable from a transmitter section (37) of any optical interface (30a-30p) to the receiver section (37) of any other optical interface (30a-30p) and monitoring an error indicator (LED) (80) illuminated by the error indicator signal. The hub (10) also provides a convenient means for testing fiber optic cable connected to the hub (10).

摘要： An optical interface which is adapted for use in a local area network is provided. The optical interface comprises an optical transmitter section and an optical receiver section. The optical transmitter section receives data in a non-return to zero inverted (NRZI) format from a LAN controller which the optical interface is part of a remote node. The optical transmitter section converts the non-return to zero inverted data to an alternate mark insertion (AMI) format. An LED driver circuit smooths out and extends the alternate mark insertion data and uses it to drive an LED. The LED driver alternately drives the LED from a fifty percent reference output level to zero percent output and one hundred percent output corresponding to alternate positive-going and negative-going transition of the data. The optical receiver section has a light sensitive detector and preamplifier which receives optical signals encoded with digital data and generates corresponding electrical signals. The electrical signals are processed by a peak pulse detector which is preferably a disk detector of the type used to detect signals generated by the read/write heads of magnetic disk media. The disk pulse detector generates unipolar digital signals corresponding to the AMI signals. A decoder converts the unipolar digital pulses to NRZI format. The NRZI data is communicated to a LAN controller when the optical receiver is part of a remote optical interface and to conventional LAN hub circuitry when it is part of a hub optical interface. The LED driver circuit comprises the entire transmitter section of a hub optical interface and receives data for transmission directly from the hub LAN circuitry.
