Abstract: Systems and methods for header compression are described. In various implementations, these systems and methods may be applicable to wireless backhaul systems. For example, a method may include receiving a packet at a backhaul modem from an Ethernet switch, the packet having an uncompressed header comprising a concatenation of at least an Ethernet and an Internet Protocol (IP) header, and a payload; parsing the uncompressed header into a plurality of fields, the plurality of fields including a static field and a derivable field; removing the static field and the derivable field from the uncompressed header; adding a compressed field to the uncompressed header to create a compressed header; and transmitting the packet with the compressed header and the payload over a wireless link.

Abstract: A Micro Telecommunications Computing Architecture, MicroTCA, test system comprises an interconnect for communication between modules of the MicroTCA test system. A test controller module, such as a JTAG, Switch Module, is coupled to the interconnect and comprises an interface for coupling to at least one unit under test. An interface module, such as a MicroTCA Carrier Hub module, receives test instruction messages from an external connection and forwards these to the test controller module via the interconnect. The test instruction messages comprise test input data for at least a first unit under test. The test controller module furthermore comprises an extraction processor for extracting the test input data from the test instruction messages; and a test controller for performing a test of the first unit under test in response to the test input data.

Abstract: A test system comprises a test processor which determines an operational status, such as a fault status, for a unit under test. The unit under test may e.g. comprise one or more boards of an electronic assembly. A presence processor generates a presence message in response to the operational status where the presence message is in accordance with a user presence message protocol. A communication controller then transmits the presence message to a remote network element of a communication network. The remote network element may be a presence server which can transmit a presence status update to associated devices. The invention may allow efficient and remote status monitoring for a test system using user presence infrastructure.

Abstract: A test system comprises a test processor which is arranged to perform hardware level tests on a unit under test. A voice interface interfaces to an external voice communication link coupled to a remote voice communication unit. A test controller is coupled to the test processor and the voice interface and comprises a script processor for executing a test control script. The test control script is in accordance with a voice scripting language standard, such as the Voice extensible Markup Language, VXML, standard. The script processor comprises a first interface for interfacing with the test processor in response to the test control script and a second interface for interfacing with the voice interface in response to the test control script. The invention may allow a user friendly speech interface to a hardware level test system.

Abstract: A telco hub in a chassis having a front side and a rear side, where the chassis includes a midplane having a first side and a second side, the telco hub includes an interposer module coupled to slidably insert into a switch slot on the rear side and connect to the second side of the midplane, a mezzanine module coupled to the interposer module, where the mezzanine module includes a telco I/O interface, where the mezzanine module is coupled to receive non-packetized telephony data. The telco hub is coupled to convert the non-packetized telephony data to packetized data, and communicate the packetized data to one or more of a plurality of payload modules over a switched fabric on the midplane, where each of the one or more payload modules is coupled to the first side of the midplane via a payload slot on the front side of the chassis.

Abstract: A boundary scan testing system may include a baseboard (102, 202), a computing module (104, 204) coupled to the baseboard, and a boundary scan test module (106, 206, 306, 406) coupled to the computing module, where the boundary scan test module is coupled to execute a boundary scan test (120, 220, 320, 420) on the computing module via a set of boundary scan instructions (114, 214) received remotely over at least one of an IP network (110, 210) and an I2C bus (211).

Abstract: A multi-service platform system (100) includes a rear transition module (102) coupled to receive a DSX signal (105) and a payload node (104) coupled to the rear transition module via a backplane (110), where the payload node is coupled to process the DSX signal. A secondary payload node (114) is coupled to secondary rear transition module (112) via the backplane. A protection bus (150) couples the rear transition module to the secondary rear transition module outside the backplane, where failure of the payload node operates to shunt the DSX signal through the rear transition module to the secondary rear transition module. Failure of the payload node operates to switch processing of the DSX signal from the payload node to the secondary payload node, and the secondary rear transition module independently controls shunting of the DSX signal through the rear transition module to the secondary rear transition module.
