Purpose (from the supplied text): The patent addresses handling of auxiliary resources—such as echo suppressors, voice prompting devices, tone transmitters, conference bridges, and announcement machines—in a telecommunication network. The excerpt states that control and handling of auxiliary resource hardware is closely related to the platform, so replacing an auxiliary resource implemented in one technique with one implemented in another generally requires redefining the interface and rewriting implementation-layer code. It also states that the CCITT M.3100 standard contains no managed objects for auxiliary resources, that the Q3 interface cannot be used for control and management of auxiliary resources, and that individual auxiliary resource positions are hard coded in the system platform, causing inefficient use and potentially long connection setup times.
Stated objects (from the excerpt): To provide a method for handling auxiliary resources in a telecommunication network in a uniform, system-independent manner, and to allow reuse of software related to modeling and control of auxiliary resources when the implementation technology changes. The excerpt is cut off mid-sentence ("Still anot…").
Plain-language scope: Based on the supplied material, the patent concerns a configuration method for managing auxiliary telecommunication resources uniformly, rather than depending on platform-specific, hard-coded interfaces.
What the excerpt does not establish: It does not include the claims, detailed description, or figures, so the precise claimed scope is not established. It does not establish litigation, ownership transfers, validity, or prior art beyond the references mentioned. Classifications listed include H04L41/00, H04L41/02, H04L41/0233, H04L41/08, H04Q3/0062, and H04Q3/54533.

All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
