A power entry module (PEM) that is used with an electronics equipment enclosure. The PEM has a housing adapted to be coupled to a shelf of the electronics equipment enclosure. The housing has at least one pair of power cable lugs accessible from an exterior of the housing for coupling the PEM to a pair of power cables associated with a power feed. The PEM also has a backplane connector for coupling the PEM to a blackplane of the electronics enclosure. A distribution network is disposed within the PEM housing and forms at least a pair of electrically isolated power distribution buses for coupling electrical power provided from the power cables to each of the power distribution branches. Each power distribution branch independently provides electrical power to at least one blade supported within the electronics equipment enclosure.

System and method for supplying power to electronics enclosures utilizing distributed DC power architectures

A blade () with first circuit entity () having a transmit output () coupled to a first connector () and a receive input () coupled to a third connector (), and a second circuit entity () having a transmit output () coupled to the fourth connector () and a receive input () coupled to a second connector (). The first, second, third and fourth connectors of the blade () are adapted to connect to a peer-to-peer backplane () that electrically connects the blade () to a remote blade () through remote connectors () on the backplane (). The backplane () cross-connects the first connector () to a remote second connector () cross-connects the second connector () to the remote first connector (). The backplane cross-connects the fourth connector () to a remote third connector () and cross-connects the third connector () to a remote fourth connector ().

Blade circuit cross-connection adapted for peer-to-peer backplanes

A system for integrated testing of one or more multi-service communications switches including a script execution environment for executing a test script. The script execution environment includes a hardware definition file storing a number of logical hardware device names corresponding to hardware devices used by the test script, including a system under test (SUT) and a number of hardware testing devices. The system further employs a network definition file including a plurality of logical connection names corresponding to connections between the hardware devices in the test environment. These connections in the network definition file are specified in terms of the logical hardware device names defined in the hardware definition file. The test script then refers to each of the hardware devices in the test environment using the logical hardware device names in the hardware definition file, and to the connections between the hardware devices using the logical connection names defined by the network definition file.

Integrated multiple services switch testing system

Flow shaping is executed at each ATM device in a virtual circuit formed in an ATM network. More particularly, the flow of data units through the virtual circuit is controlled at each ATM switch such that the variable transmission delay remains substantially constant from hop to hop. Flow shaping at each device causes variable transmission delay to remain substantially constant throughout the virtual circuit, thereby allowing formation of an ATM virtual circuit having an arbitrarily large number of ATM switch &ldquo;hops&rdquo; without constraints imposed by required playout buffer size. Further, the invention minimizes end-to-end delay.
