Filed:

Dec 30, 2009

Appl. No.:

12/649854

Inventors:

Jason R. Ferguson - Phoenix AZ, US

Assignee:

Adtran, Inc. - Huntsville AL

International Classification:

H04J 3/06

US Classification:

370509

Abstract:

An interworking function (IWF) at an edge of a packet network comprises a primary receiver and a backup receiver. The primary receiver receives data packets and timing information from a packet network. The primary receiver interworks data from the data packets into a data signal that is based on a local clock signal. The primary receiver uses the timing information from the packet network to adjust the frequency of the local clock signal such that it is synchronous to a network clock signal, such as a clock signal at an IWF, referred to as the “transmitting IWF,” that transmitted the data packets. In addition, the primary receiver from time-to-time provides timing information, such as a frequency control word, to the backup receiver, which uses such timing information to synchronize a clock signal of the backup receiver to the network clock signal upon an occurrence of a switchover from the primary receiver to the backup receiver. By using the timing information from the primary transceiver, the backup transceiver is able to synchronize its clock signal to the network clock signal in less time.

International Classification:

H02J 1/00

US Classification:

307 80, 307 81, 307 64, 307 87

Abstract:

The present disclosure generally pertains to systems and methods for swapping span power modules that are used for supplying power to network interface units (NIUs). A span power module in accordance with one exemplary embodiment of the present disclosure has logic capable of communicating with logic of another span power module. When one module is to be swapped for the other module, the module being swapped-in is configured to automatically disable the other module shortly after it has powered up and is supplying electrical power across a span line. The amount of time that both modules supply power to the span line is sufficiently small such that damage to electrical communication equipment receiving power from the span line is prevented.

International Classification:

H04L 25/03

Abstract:

Described are systems and methods take advantage of properties of sinc filters that remove frequency components at specific integer multiples of a noise frequency. In various embodiments, sampling of multi-channel systems at sufficiently high rates allows for removal of unwanted signals and harmonics from multi-sample sequences. Advantageously, a multi-sample sequence scheduling scheme eliminates the need for noise filtering one channel at a time at each channel's own sampling rate using a separate filter.

International Classification:

H04W 16/14
H04W 56/00
H04W 12/06
H04W 72/04

Abstract:

An LTE preemption system may allow authorized users to access LTE spectrum when needed by the authorized users and allow commercial users to access the LTE spectrum when not in use by the authorized users. An authorized transmission unit may transmit noise in at least one of a primary synchronization channel, a secondary synchronization channel, or a physical broadcast channel. The noise may prevent commercial users from accessing the LTE spectrum. At least one of the primary synchronization channel, the secondary synchronization channel, or the physical broadcast channel may be offset by a known time or frequency, and authorized devices may utilize the LTE spectrum by searching for the channels at the offset locations.
