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.

A housing for an outside plant telecommunication equipment (OSP) which uses modular heat sink assemblies. OSP housings contain electronic circuit boards on which are mounted electrical components that generate heat.

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.

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.

Signals entering outside plant (OSP) telecommunications enclosures typically do so through weather tight connectors, with one connector mounted to the enclosure and a mating connector connected to a cable bringing the signals to the OSP housing. Such connectors are expensive and require extensive effort to connect the wires of a cable bundle to the connectors. These problems are avoided by allowing cables pre-installed with a cable seal and pre-terminated to cable connectors to pass through an opening in the wall of an OSP housing and seal the cable bundle to the housing to prevent the ingress of environmental elements into the housing through the opening. This permits easier installation and retrofitting of electronic equipment contained within the housing.
