The invention is a novel method and apparatus for controlling the flow of traffic between a host digital terminal (HDT) and a plurality of optical network units (ONUs). Each ONU is connected to the HDT by optical fiber and to a plurality of subscribers by a respective plurality of subscriber drops (typically pre-existing copper twisted pairs). The bandwidth on the fiber, although large, is usually inferior to the total bandwidth that can be transmitted across the subscriber drops. Therefore, both upstream and downstream traffic may become congested at various "choke points" under certain circumstances of usage. Ordinarily, the data is buffered at the choke points, leading to the installation of large queues within each ONU. This solution is not only expensive, but is inadequate since the required queue size is dependent on the maximum transaction size, which has no hard upper bound. In contrast, the present invention provides a traffic shaper located in the HDT, which gives centralized control of the traffic flowing to and from the ONUs. Consideration of the priority and destination of each traffic cell is taken into account by the traffic shaper to ensure that the capacity of the fiber and of the individual drops is never exceeded, irrespective of the transaction sizes, thereby eliminating the need for costly buffers in the outside plant. Any maintenance or repairs of the traffic shaper can be easily effected without field visits, due to its centralized location.

An outside Plant Construction Management (OSPCM) system simplifies and mechanizes many aspects of operating a facility, such as a Regional Bell Operating Company (RBOC). The OSPCM system performs a configuration function and this data is input to the awarded contract which entails breaking the job into its constituent tasks, sequencing the tasks, prioritizing the tasks, and scheduling the tasks. The OSPCM system completes the scheduling task by assigning the tasks to supervisors and/or to outside contractors. The OSPCM system automatically manages the materials required for tasks by determining what and when it is needed, ordering what is available from within inventory, and ordering necessary materials from outside providers. When a task is completed, the contractor accesses the OSPCM system and marks the task as completed. The OSPCM system then forwards invoices to the voucher system for those cases where work is completed as designed.

According to an example embodiment of the invention a one-piece retention housing is utilized for terminating an optical fiber cable. The retention housing attaches to strength members within the cable, providing tensile strength and a means for further mating with components of an optical fiber connector assembly. The retention housing is used as part of a kit for terminating and securing the optical fiber cable connector to a complementary receptacle or terminal for drop-cable deployments in optical access networks and outside plant applications.

An outdoor equipment cabinet includes a housing with a first door for accessing an equipment compartment within the housing. A battery compartment is located proximate a bottom of the housing. First and second air vents are located in an upper half of the cabinet. At least one fan moves air from the first vent, down to the battery compartment and then up and out of the second vent. In some embodiments, the first door includes the second vent, and a dual wall construction leading to a heat exchanger mounted to the first door. Air passes through the dual wall construction of the first door and through the heat exchanger to regulate an air temperature within the equipment compartment, and then passes out the second vent. The first vent may be provided in a second door which also includes a dual wall construction to guide incoming air to the battery compartment.

A method of regulating traffic flow to customer premises devices (CPDs) reachable via outside plant units (OPUs). The method comprises receiving first packets in a first traffic category via a first interface, the first packets being destined for respective CPDs; receiving second packets in a second traffic category via a second interface, the second packets being destined for respective CPDs; determining a destination OPU for each of the first and second packets. For each particular OPU that is the destination OPU for one or more packets, the packets are buffered and transmitted via an OPU interface for the particular OPU. The destination OPU for a particular packet is determined by identifying the OPU via which the CPD for which the particular packet is destined is reachable. Packet flow via the OPU interface is regulated by prioritizing transmission of first packets over transmission of second packets.

An xDSL splitter module is provided for mounting in a network interface device (NID) that contains an xDSL splitter circuit and the terminals to connect the circuit between outside plant wires and two pairs of inside wires to deliver POTS and xDSL to the subscriber. The module also has at least a demarcation point for the POTS signal.

A distributed DSLAM, which comprises a head end subsystem located within a switching facility and a remote subsystem located outside of the switching facility. The head end subsystem is operative for routing streams of data from a data network to the remote subsystem over a communication link, while the remote subsystem is operative for transmitting over a set of local loops analog signals comprising digitally modulated versions of the data. Separating the routing and modem functionality between inside and outside plant facilities reduces heat dissipation in the outside plant, leading to increased reliability. Flow control can be performed in the upstream and downstream directions by transmitting portions of individual packets and withholding other portions of individual packets. This is done instead of withholding the transmission of entire packets. As a result, the perceived impact on video quality, for example, is lessened.

Embodiments detect issues in an outside plant utilizing a connectivity trail that indicates network elements (NEs) starting at the headend and ending at a distribution tap that serves one or more customer premise devices associated to a customer account. Embodiments determine a failed NE that serves the highest number of customers for which a trouble is reported to a ticketing system. Embodiments avoid reporting downstream child NEs that may be performing poorly due to the upstream failed parent NE. Embodiments associate the one or more customer premise devices, and a customer account with respective NEs of the connectivity trail, perform operational metric tests to determine whether a customer premise device associated with a customer account has failed, determine when an NE of the connectivity trail has failed. Embodiments also include rebooting the failed NE and/or notifying a ticketing system accordingly.
