Encrypts voice traffic
Manages cellular handovers
Monitors IP traffic
Aggregates multiple DSL subscriber lines
A DSLAM (Digital Subscriber Line Access Multiplexer) aggregates individual DSL subscriber lines at a local exchange for transport over a high-capacity backbone. It does not handle encryption, cellular handovers, or IP traffic monitoring directly.
Which organization sets global telecom standards?
Federal Communications Commission
International Telecommunication Union
Institute of Electrical and Electronics Engineers
3rd Generation Partnership Project
The International Telecommunication Union (ITU) is a United Nations agency that develops global telecom standards. The FCC regulates U.S. communications, IEEE develops broad technical standards, and 3GPP focuses on mobile communications specifications.
Which system in telecom provisioning verifies inventory availability and capacity before activation?
Operations Support System
Customer Relationship Management
Network Management System
Business Support System
An Operations Support System (OSS) handles network inventory, service provisioning and resource management, ensuring capacity and availability. BSS focuses on billing, NMS on monitoring, and CRM on customer data.
Which billing model charges customers based on actual data usage?
Usage-based billing
Flat-rate billing
Subscription billing
Tiered billing
Usage-based billing charges customers in proportion to their consumed data volume. Flat-rate billing charges a fixed fee, tiered billing uses predefined buckets, and subscription billing is typically a recurring flat fee.
In fault management, what does MTTR stand for?
Maximum Time To Resolve
Mean Time To Respond
Minimum Time To Recover
Mean Time To Repair
MTTR stands for Mean Time To Repair, indicating the average time required to fix a failed component. It is distinct from response time or other non-standard measures.
Which U.S. regulation requires telecom providers to facilitate law enforcement eavesdropping?
Sarbanes-Oxley Act
Communications Assistance for Law Enforcement Act
General Data Protection Regulation
Health Insurance Portability and Accountability Act
The Communications Assistance for Law Enforcement Act (CALEA) mandates that telecom carriers build in capabilities for lawful interception. GDPR is an EU data protection law, HIPAA covers health data, and SOX governs financial reporting.
Which tool provides real-time network traffic monitoring and visualization?
Network Management System
Business Support System
Customer Relationship Management
Operations Support System
A Network Management System (NMS) collects and displays real-time performance metrics and traffic patterns. OSS and BSS focus on operations and billing, while CRM handles customer data, not live network metrics.
What is the role of a Base Station Controller (BSC) in GSM networks?
Encrypts subscriber voice traffic
Routes IP packets between networks
Manages radio resources and handovers
Processes customer billing information
A BSC manages radio channel assignment, power control, and handovers in the GSM air interface. Routing IP packets is a router's function, billing is BSS, and encryption is handled by the AUC and BTS.
During service commissioning, which test verifies end-to-end service performance from user device to network?
Integration Testing
Regression Testing
Unit Testing
Acceptance Testing
Acceptance Testing checks the complete service path against requirements and validates performance from the customer's perspective. Unit testing isolates components, integration focuses on combined modules, and regression retests fixes.
In postpaid billing, when are usage charges applied?
After the service usage period ends
Before usage begins
At the time of provisioning
Real-time during usage
Postpaid billing accumulates usage over a billing cycle and applies charges after the period ends. Prepaid charges happen before or during usage, and real-time billing applies in some prepaid models, not postpaid.
What is the recommended initial action when handling an escalated customer complaint?
Offer discounts before investigation
Apologize without gathering details
Listen empathetically and clarify concerns
Transfer immediately to a supervisor
Best practices in customer support emphasize active listening and clarifying the customer's concerns to understand the issue fully. Immediate transfer, unqualified apologies, or premature discounts can undermine resolution quality.
Under EU regulations, which framework protects subscriber personal data?
General Data Protection Regulation
Payment Card Industry Data Security Standard
FCC Privacy Rules
Health Insurance Portability and Accountability Act
The GDPR is an EU regulation that establishes strict rules for processing and protecting personal data. The FCC regulates U.S. communications, PCI-DSS focuses on payment data, and HIPAA covers U.S. health information.
How does MPLS improve packet forwarding efficiency in telecom networks?
It assigns short fixed-length labels for routing decisions
It bundles packets into larger frames
It encrypts traffic to reduce overhead
It increases the IP packet time-to-live
MPLS uses fixed-length labels to make forwarding decisions quickly without complex route lookups. Changing TTL or encryption does not inherently speed forwarding, and bundling packets increases latency.
What is the primary function of a mediation system in telecom billing?
Generate customer invoices
Collect and normalize raw usage records for billing
Authenticate subscribers on the network
Monitor real-time network performance
A mediation system aggregates CDRs or raw usage data from various network elements and normalizes them for downstream billing processes. Invoicing, authentication, and performance monitoring are handled by other systems.
In convergent billing solutions, what is a key benefit?
Increased billing cycle length
Separate billing platforms per service
Manual reconciliation of service charges
A single invoice covering multiple services
Convergent billing consolidates charges across voice, data, and other services into one invoice, improving customer experience. It does not extend cycles, use separate platforms, or require manual reconciliation.
Which statistical analysis method helps detect intermittent network faults by analyzing time series data?
Clustering
Trend analysis
Classification
Correlation
Trend analysis examines performance metrics over time to identify patterns or anomalies indicating intermittent faults. Classification and clustering group data points, while correlation measures relationships but not time-based trends specifically.
Under network neutrality principles, which practice is disallowed?
Providing equal access to all content
Paid prioritization of specific traffic
Transparent traffic management
Caching popular content locally
Paid prioritization, where specific traffic is given preferential treatment for a fee, violates net neutrality. Equal access, transparent policies, and caching to improve performance are generally permitted under neutrality rules.
