Filed:

Dec 27, 2000

Appl. No.:

09/748837

Inventors:

David C. Curtis - Crofton MD, US
Christopher Selwood - Bethesda MD, US

Assignee:

Wisor Telecom Corporation - Rockville MD

International Classification:

G06F 17/60

US Classification:

705 7

Abstract:

A system for management of an integrated communications provider comprising a means of automatically retrieving customer service records and preparing sales proposals therefrom. The invention further comprises components for pre-ordering management functions, circuit management, design management, service management, and gateway to incumbent local exchange carriers and trading partners. The system incorporates features that automate comparisons between existing services and proposal services, alarming of failures of confirmations, optimizing on-net and off-net services, creation of cutover reports and issuance of service requests to local exchange carriers and trading partners.

US Classification:

37922102, 37920103, 705 8, 705 9

Abstract:

A system manages the operations of an integrated communications provider. One aspect of the system is a work flow engine. The work flow engine decomposes the service model into sub-model components based upon whether crossing of plural networks is appropriate to provide requested telecommunication services and which service providers are available to provide service consistent with the location of the customer. The work flow engine also creates a telecommunications design from the sub-model components based on order rules of the service providers. The system automatically retrieves customer service records and preparing sales proposals based on those records. The system includes a gateway to incumbent local exchange carriers and trading partner service providers. The system incorporates features that automate comparisons between existing services and proposed services, optimizing on-net and off-net services, creation of cutover reports, issuance of service requests to local exchange carriers and trading partners, and alarming of failures of confirmations.

US Classification:

370516

Abstract:

An arrangement (apparatus and method) for monitoring jitter caused during transport of digitally-coded information in a packet switched network, and for managing network operations in accordance with the detected jitter. The detected jitter is used to determine whether corrective action is necessary, such as rerouting network traffic, or performing network maintenance. The disclosed arrangement detects program clock reference (PCR) values from an MPEG-encoded transport stream, whereby each pair of PCR values represents an expected arrival time of a corresponding stream segment. An actual arrival time for the corresponding stream segment is determined in response to detection of the corresponding PCR values and an independent clock signal. The expected arrival time of the stream segment and the actual arrival time are correlated with an accumulation of expected and actual arrivaimes of previously-received data packet stream segments in order to determine the jitter in the digital data stream. The jitter is corrected by a combination of adaptive buffering techniques and restamping the PCR value with corrected values coinciding with the actual arrival time of the stream segments.
