What is an ecosystem consisting of modernized events and scoring that aligns with the customer experience?
ANS; If a customer is experiencing issues with video calls, uploads, and online gaming.
This refers to the overall system that monitors and scores customer experience.
What is the most likely alarm type to be sent out in the node if a customer is experiencing issues?
Upstream Alarm
What may be experienced if a downstream alarm isn’t addressed quickly?
Slow internet speeds, buffering, or complete service interruptions.
Why are Connectivity alarms critical?
They indicate that customers are unable to access the internet or any services at all.
What are Downstream, Upstream, and Connectivity alarms examples of?
DM alarms
What do Upstream DM alarms primarily monitor in a network?
Transmit power levels, noise, and packet error rates from the customer to the network.
Why are Downstream DM alarms important to monitor?
They help detect and prioritize issues affecting data sent from the network to the customer.
What are the key factors in DM Scoring?
Severity of Degradation, Number of Impacted Customers or Devices
What does the score reflect in DM Scoring?
The severity of the problem. As the issue worsens, the score increases.
What does the score consider in DM Scoring?
The number of customers or devices affected by the issue.
What condition does any score above 1000 represent?
Demand Maintenance
How does the scoring model prioritize issues?
As the severity of the issue increases and more customers are impacted, the score increments progressively.
What does the progressive model help with?
Prioritization of the most critical issues that require immediate attention.
How often does the scoring model utilize real-time telemetry?
Every 5 minutes, but updates the scores hourly.
When are DM alarms generated?
In real-time.
At what level is ANS scored?
Event level, not at the node level.
What type of scoring receives higher scores for more severe problems?
Severity-Based Scoring
What does the Outage or Total Loss of Service Alarm represent?
The highest severity level of network impairment.
What is the score for a Tier 1 alarm in the ANS model?
4,000 or higher.
Name the events in the demand alarm category.
Downstream Packet Error Rate, Upstream Uncorrectable Code Word Errors, Intermittent Connectivity, Total Loss of Service (Outage).
What triggers a Tier 2 alarm?
Intermittent connectivity issues or packet loss that degrade service quality with a score between 1,000 and 3,500.
What are the Tier 1 Alarms on the alarm pyramid?
Outage / Total Loss of Service.
What are the Tier 2 Alarms on the alarm pyramid?
Connectivity issues (intermittent, packet loss).
What are the Tier 3 Alarms on the alarm pyramid?
Transmission quality (e.g., correctable code word errors).
