Apparatus and methods for managing communication system resources are disclosed. Based on status information received from a resource itself or from other sources, an operational status of a maintenance resource to perform a predetermined maintenance operation on a target communication system resource, for example, may be determined. Access to use resources in performing operations may also be controlled. Resource access is granted or denied based on an availability status of a resource. Other parameters such as relative priorities of a new request to use a resource and a current operation for which access to use the resource was previously granted may also be used in determining whether to grant access to use a resource. A resource may be reclaimed for a higher priority operation for instance. Redundant or alternate resources may also be identified where a resource is not operational or otherwise not available.

Apparatus and methods for managing communication system resources

Subscriber line maintenance apparatus and methods are disclosed. A maintenance operation is performed on a subscriber line in a communication system by an embedded test unit. The test unit limits an effect of the maintenance operation on communication signals that are transferred on the subscriber line during the maintenance operation. In one embodiment, the communication signals are high-frequency signals, and the limiting is achieved by performing the maintenance operation through a low-pass filter, such as the low pass filter of a Plain Old Telephone Service (POTS) splitter. The test unit may be implemented as a daughter card carried by another electronic circuit card in a Digital Subscriber Line Access Multiplexer (DSLAM), for example, so that the test unit does not occupy its own card slot in an equipment shelf. One, or more than one, test unit may be provided to serve multiple equipment shelves in a distributed communication equipment architecture.

Subscriber line maintenance apparatus and methods

A multi-dwelling unit (MDU) module is configured for providing telephony communicating services and non-telephony services. The MDU module includes a motherboard and a plurality of service units connected to the motherboard. Each one of said service units and the motherboard are jointly configured for providing non-telephony service and telephony service to a plurality of service subscribers. The motherboard is configured for providing overload power management to limit power consumption associated with said telephony services during an overload condition and for providing lifeline power management to limit power consumption associated with said non-telephony services during a power outage condition. The MDU module optionally includes lightning primary surge protection blocks configured for being connected to the service units. The MDU module includes a passive heat dissipation assembly that is configured for absorbing heat generated by the motherboard and the service units and for passively dissipating the heat.

Multi-dwelling unit module for passive optical networks

Distributed communication equipment architectures and techniques are disclosed. A host system includes an expansion unit through which control information and communication traffic may be exchanged with an expansion system. The expansion system is thereby controllable by a controller at the host system, significantly simplifying the design and reducing the cost of the expansion system. The expansion unit for a host system may also provide one or more configurable communication link interfaces. Each configurable interface may be independently configured as a network-side interface for connection to upstream communication equipment or as an access-side expansion interface for connection to an expansion system, allowing provisioning of network and access interfaces at the host system as needed.
