摘要： An apparatus and method are described that allows for improved wander jitter reduction in communication devices and associated communication links, in particular on HDSL communication devices and links. The improved device apparatus and method detects the current data rate offset of the HDSL data rate being utilized and the data rate of the datastream being transmitted through the HDSL communication link and allows for the transmitting HDSL communication device to adjust the HDSL data rate to avoid high wander jitter nullsweet spotsnull. The improved device apparatus and method also allows for the profiling of communication devices for their specific high wander jitter sweet spot maximum points by sweeping the input data rate being transmitted at differing HDSL data rates.

摘要： A method for correlating an input signal to a signature is provided. The method compares an input stream with a signature element-by-element as the input stream is received. The method restarts the comparison using the first element of the signature when an element in the input stream does not match the compared element in the signature and declares correlation when consecutive elements in the input stream match corresponding elements of the entire signature.

摘要： An apparatus and method is described that allows for improved transmission of EOC data over the EOC channels of communication devices and links, reducing the number of dropped EOC packets and increasing the bandwidth and robustness of the EOC channel. The improved device apparatus and method also allows for the reduction of the overhead of EOC channel error detection and correction on the limited resources of the communication device by aborting a corrupted or blocked EOC packet transmission and automatically resending. The improved device apparatus and method additionally allows the reduction of dropped EOC data packets due to corrupted transmission and the resultant miscommunication and corruption of high-level applications of the communication device, such as operation commands, remote configuration and management programs, and operation displays.

摘要： Testing of analog-to-digital and digital-to-analog converters formed in integrated circuits. In one embodiment, a method of testing an analog-to-digital (A/D) converter comprises applying an analog test signal of a first frequency to an input of the A/D converter. Sampling digital byte samples from an output of the A/D converter at a second sampling frequency and comparing select digital byte samples with each other. When the select digital byte samples match, storing a verify bit in a memory to verify the A/D converter is working. In another embodiment, a method of testing a digital-to-analog (D/A) comprises creating repeating digital byte samples with a logic circuit formed in the integrated circuit. Converting the repeating digital byte samples into an analog test signal with the D/A converter. Comparing the frequency of the analog test signal with the frequency of an expected analog signal to determine if the D/A converter is working.

摘要： A communication system includes a local unit that has a lower data link layer and a session layer running a data pass-through application and a user interface. The data pass-through application lets the data link layer in the local unit pass data through to a remote unit. The remote unit has a lower data link layer and a session layer executing a user interface. When the data link layer detects that the session layer is unstable and/or locked up, the data link layer transmits a disconnect request to the local unit's data link layer. All further user data sent to the local unit's data link layer is routed to the local unit's user interface.

摘要： A system uses a resource locking token to allow various processes to have exclusive access to a system resource. The process that receives the token then requests that a local database be updated/synchronized with a master database. The process continues checking the synchronization status every time it gets the token. When the process receives the token and the synchronization is complete, the local database is accessed and the data is used in accessing the system resource. The token is then returned to the system.

摘要： A fault warning system controls light sources and a warning signal to provide an indication of fatal and non-fatal faults in a communication system. The circuitry uses a pull-down circuit in electrical communication with light and signal control circuits. The circuit can be operated to activate a first light emitting diode (LED) if an operational status of a monitored circuit is either fatal or non-fatal fault. The circuit can be operated to deactivate a second LED if an operational status of a monitored circuit is fatal, and the second LED remains active if the operational status of the circuit is a non-fatal fault.
