Abstract: A method, apparatus, and computer-readable medium for administering the implementation of product change notices (PCN). A PCN database application server computer is utilized to provide a method for implementing a change to telecommunications products. The method includes the steps of receiving a PCN that identifies the change, determining whether the PCN satisfies the implementation requirements, and if the PCN does satisfy these requirements, implementing the change. Once the PCN is received, it is monitored for conformance to an implementation schedule and updated for progress until completion. Updates may be received from remote inventory systems or suppliers. Upon completion or rejection of the PCN, the PCN is closed.

Abstract: A circuit for reading and programming a fuse. The electronic circuit includes a data fuse coupled to a data node and a reference fuse coupled to a reference node. A programming circuit is coupled to the data node, wherein the programming circuit is configured to, when activated, cause the data fuse to be programmed. A sensing circuit is configured to draw current from the data node and the reference node in order to develop a voltage differential between the data node and the reference node during a read operation. A read circuit is configured to, when activated, enable the sensing circuit to develop the voltage differential during the read operation. A protection circuit is configured to form a voltage divider within the sensing circuit during programming of the fuse.

Abstract: A level shifter circuit and method of operating therefor. The level shifter circuit is coupled to receive a data signal via an input circuit, wherein the input circuit is in a first voltage domain. The level shifter circuit is also coupled to receive a clock signal from a second voltage domain. On a first portion of the clock cycle, true and complementary output nodes of the level shifter circuit (which are in the second voltage domain) are pulled to a first voltage by activation of respective pull transistors. On a second portion of the clock cycle, one of the true or complementary output nodes is pulled to a second voltage on a second voltage node by enabling the supply to the latch. Data is captured by the keeper, outputting true and complementary versions of the data signal in the second phase of the clock.
