Abstract: Described are methods and apparatuses for optical digital communications. In one aspect a method includes assigning, by an optical line terminal (OLT), different time slots to different optical network units (ONUs) for data transmission by the different ONUs in a time domain multiple access (TDMA) system. The method further includes sending, by the optical line terminal (OLT), bandwidth allocations to the different ONUs, and determining an optical power in each time slot assigned to the different ONUs. The method further includes detecting a power change in a first assigned time slot between a previous first optical power and a first optical power associated with a first ONU, wherein the detecting the power change indicates a faulty ONU is transmitting to the OLT.

Abstract: An Optical Line Terminal (OLT) includes a downstream transceiver coupled to a Passive Optical Network (PON). The downstream transceiver is configured to communicate over a plurality of bonded channels. The OLT also includes an upstream transceiver configured to receive a downstream Service Data Unit (SDU) including user data. A processor is coupled to the upstream transceiver. The processor is configured to split the downstream SDU into a plurality of downstream blocks. The processor distributes the downstream blocks amongst the bonded channels based on bonded channel availability for transmission over the PON via the downstream transceiver.

Abstract: A fixed wireless access network provides for high-frequency data links between aggregation nodes and endpoint nodes. The system further provides for lower frequency wireless data links, which have carrier frequencies less than high-frequency wireless data links. These lower frequency links provide for auxiliary communications between the aggregation nodes and one or more endpoint nodes. During normal operation, the nodes exchange packet data via the high-frequency data links. However, when impairment of the high-frequency data links is detected, the nodes direct the packet data over the low-frequency data links instead until the high-frequency data links are no longer impaired.

Abstract: The present invention relates to packet-switched networks, such as Ethernet, and more particularly to a method for traffic shaping of data frames to transmit in such a telecommunication network, the frames to transmit being distinguished between: express frames, needing to be sent within predetermined time windows, and normal frames, intended to be sent at times outside said time windows. More particularly, for a current normal frame, the method comprises the steps of: determining whether said normal frame can be fragmented, and if yes: determining whether a remaining time to a next time window opening is enough to transmit one or several fragments of said normal frame, and if yes: transmitting said one or several fragments.

Abstract: A process for allowing a CMN-4 equipped Link 16 terminal to enter an active network. After an initial entry command is entered at the terminal at a given current time at the terminal, a number of time slots are identified in which multiple receivers at the terminal have an opportunity to detect an initial entry message (lEM) after the given current time. Each of the receivers is set to detect an lEM during a different one of the identified time slots. When an lEM is first detected by one of the receivers, the current time at the terminal is reset based on the time slot in which the I EM was detected.

Abstract: A system and method for testing lines to determine service-affecting conditions on a line, such as telephone wiring. Conditions may be identified from low frequency variations in a frequency spectrum measured on the line. The line may be stimulated with a broad spectrum signal, such as may be generated by a DSL modem operating in the LO state or may be the result of noise on the line. Analysis of the low frequency variations may yield information about the nature of service- affecting conditions allowing conditions, such as un-terminated or poorly-terminated extensions to be identified. The method may be performed by a test device attached to premises wiring in a telephone network and used to determine whether the premises wiring will support VDSL2 or other high speed data services without modification or may indicate changes at the premises to enable the wiring to support high speed data services.
