What CPNI Generally Means

Under U.S. communications law, CPNI generally concerns information related to the quantity, technical configuration, type, destination, location and amount of use of a telecommunications service, together with related billing information, when available to a carrier by virtue of the customer relationship.

Information Potentially In Scope

Depending on ARCAMUSA’s legal classification and the service, call-detail, destination, service-configuration, usage and billing information may qualify. This page does not predetermine the legal classification of every record.

Protection Principles

Potential CPNI should be treated as confidential, accessed only for legitimate roles and protected through appropriate customer authentication before disclosure. Disclosure and use must follow applicable law, customer authorization and valid legal process.

Operational Uses

Where permitted, information may support service delivery, billing, repair, security, fraud prevention, customer support and protection of rights and property. Marketing use is limited to what applicable law and operational procedures permit.

Where CPNI rules apply, ARCAMUSA may use CPNI to provision, bill, maintain, protect and support the service from which the information is derived, and for other purposes only with authority supplied by law or a valid customer approval. Marketing use is not inferred from operational access.

Customer Rights

Applicable rights may include limits on certain uses or disclosures. No opt-out method is advertised until ARCAMUSA confirms the applicable rule and can operate the required process.

Applicable CPNI Protections

ARCAMUSA protects information that constitutes CPNI in accordance with applicable law. Applicable customer rights, uses and disclosures are governed by federal communications law and the applicable service relationship. This public notice does not expand or reduce duties established by law.

Scope and Definition

CPNI generally concerns information relating to the quantity, technical configuration, type, destination, location and amount of use of qualifying telecommunications services, together with related billing information, as defined by applicable law.

Protected Categories

Depending on the service and legal classification, protected information may include service configuration, usage and destination details; not every business record is necessarily CPNI.

Operational Uses

Where permitted, information may be used to provide, troubleshoot, protect, bill and support the service from which it is derived and for related legally authorized purposes.

Authentication

Requests for access or changes are subject to reasonable verification of customer identity, representative authority and approved account channels.

Access and Disclosure

Access is limited according to role and purpose. Disclosure to vendors, networks or authorities must have an operational, contractual or lawful basis and appropriate safeguards.

Marketing Restrictions

CPNI will not be used for marketing where consent or another legal basis is required unless the applicable requirements have been satisfied.

Security and Incidents

Suspected unauthorized access or disclosure is assessed under applicable security, incident-response and notification requirements.

Customer Responsibilities

Customers must protect account access, maintain authorized representatives and promptly report suspicious activity or inaccurate permissions.

Complaints and Requests

Questions or requests may be routed through the structured Contact page and will be evaluated after appropriate identity and authority verification.

ARCAMUSA records the nature, receipt date, authentication outcome, disposition and material communications for a CPNI complaint or access request when recordkeeping is applicable. Records are retained according to the governing requirement and are not used to broaden disclosure beyond the verified request.

Contract Hierarchy & Related Documents

This policy applies when information qualifies as Customer Proprietary Network Information under applicable telecommunications law. The broader Privacy Notice continues to govern business-contact, website and diligence information that is not CPNI.

A data processing addendum does not expand permitted CPNI use or bypass customer authentication. If a contract provision conflicts with a non-waivable CPNI safeguard, the safeguard controls; service-specific access permissions remain subject to verified account authority.
