CSR Training - Quiz Guide

  1. Are there any fees associated with late or missed payments? If so, describe them.

    Late
    Fees
    - Late fees apply to a customer when they fail to pay on time. The payment is due on the 1st of every month and the late fee applies when they fail to pay in by the due date of 11th. After the 13th they become delinquent and are not only responsible for the late fee and paying the original amount but they also have to pay a reactivation fee ($25) if there account was deactivated for non payment.

  2. PowerCode shows a radio offline for 3 days. PoE checks out fine. Power cycle does not restore connectivity. What is the most likely issue and next step?

    Radio - More than likely a failed radio however TRY to bypass the router and see if they get link.


  3. Customer reports that their internet connection drops whenever it rains. What is the most likely cause?

    Rain Fade - This can cause issues on the network (Certain areas affected more than others). Know when to use this term and when to not. We should not be telling clients the problem is due to Rain Fade.


  4. An ethernet link shows 10base-T Half Duplex. What is the best next step?

    Ethernet Link - Test the cable by plugging it into another device and see if the negotiation remains the same. If it does it's a bad cable if not it could be a bad port on the device.

  7. What signal level is considered good on a PMP450?

    Signal level - While signal level may vary a good signal is general considered to be -60dBm or higher.


  8. What SNR is considered good on a PMP450?

    SNR - Should be 20+dB or higher, if it's lower we should investigate the cause.


  9. How do we send invoices/bills to customers?

    Billing - Is done entirely in PowerCode, In this specific case the system sends them an invoice via email.


  10. (A) Customer radio is online but slow. List the triage steps in order (at least 6).  (Split into two questions)

    Check RF stats (signal, SNR, modulation)
    Check ethernet link (negotiation, errors)
    Verify radio uptime/stability
    Define what “slow” means
    Perform bypass test
    If bypass is good → customer network issue
    If bypass is slow → continue network troubleshooting

    10. (B) Customer radio is online but navigating the radio is slow. What is your triage approach?

    Check RF stats
    Check latency/packet loss to radio
    Check AP health/load
    Determine if other customers are affected
    Check backhaul performance
    Identify if issue is isolated or sector-wide
    Escalate if needed


  11. PoE light fades slowly when unplugged from power. What does this mean?

    Likely:
    Bad/disconnected cable
    Failed radio


  12. PoE light turns off immediately when you plug the radio cable into the PoE. What does this indicate?

    Indicates short or fault
    Likely:
    Bad cable
    Failed radio
  13. Do we offer 24/7 call center support? If so, what is the process for after-hours escalation?

    Call Support - We do offer 24/7 support, the structure is built as follows.
    Mon-Fri 8AM-6PM NOC Support / Sat 9AM-1PM NOC Support
    After hours:
    Calls handled by ServerPlus
    PowerCode ticket is created
    Our team reviews and addresses the issue


  14. What is CCQ on Ubiquiti and what should it be?
    Client Connection Quality
    • 100% CCQ → your link is delivering perfect efficiency (no wasted airtime)
    • 50% CCQ → half your airtime is wasted (retries, drops, inefficiencies)

    So CCQ is not just signal strength—it’s link efficiency.

    The CCQ should effectively be at or above 90% any lower than that and there are issues we should investigate.



  15. What day of the month do we bill customers?

    Billing Cycle - We bill on the 1st of the month, the client is late if they do not pay by the 11th of the month and they are delinquent if they haven't paid by the 13th of the month.


  16. Where can a customer find our Terms of Service? (Multiple Choice)

    They can find it on our website Bertram Communications, They also should have a copy from their bill that is emailed to them every month.

    Note: Our (ToS) is inherent, meaning, if they pay the bill they by default accept the terms. 


  17. Bypass test shows good speeds but customer says WiFi is still slow. Whose problem is it?

    Issue is customer router / internal network
    If managed router → we troubleshoot
    If customer-owned → provide guidance/resources
    Adjust support based on workload and availability


  18. Explain what a vacation hold is and how it can be used. What are the limitations?

    Insert Answer Here (Eric and Tim weigh in)


  19.  A customer calls wanting to cancel their service. What are some strategies or options you can offer to try and retain them? (List at least 4 approaches or incentives).

    Identify reason for cancellation
    If service issue → fix it
    If price issue → offer discount
    If speed issue → offer higher plan
    If leaving regardless → offer $10 backup service


  20. At what signal level should you consider escalation or truck roll?

    -75 dBm or worse (approaching -80 dBm)


  21. Describe the bypass test procedure step by step.

    Unplug WAN cable from router
    Plug into test device
    If NAT/Option 82 → no changes needed
    If bridged → add device MAC in PowerCode
    Test connectivity and speeds


  22. Customer has a PMP450 that keeps dropping every 5-10 minutes, but signal is -60 dBm (good) and SNR is normal. What's your triage approach?

    Check system uptime
    If resetting → power issue
    Check PoE, outlet, switch-controlled outlets
    If stable:
    Check session drops
    Check ethernet issues
    Check AP / other users
    If multiple users affected → escalate


  23. ePMP uses CINR instead of SNR. What value is considered good?

    20 dB or higher

    CINR (Carrier to Interference-plus-Noise Ratio) - Roughly the same value as SNR CINR is explained below.

    CINR vs SNR (Why Cambium Uses CINR)

    SNR (Signal-to-Noise Ratio)
    Only considers noise floor
    Assumes no external interference
    Works fine in clean lab conditions

    CINR (Real-World Metric)
    Includes co-channel interference
    Reflects crowded RF environments (WISPs, urban areas)
    Much more predictive of actual throughput

    In modern unlicensed bands (2.4 GHz, 5 GHz), interference is usually much larger than noise, so SNR becomes misleading.


  24. Describe our cancellation policy. Do customers get a refund if they cancel mid-month?

    30-day notice required
    $350 ETF if under contract
    Equipment:
    Return themselves, or
    $50 pickup fee
    If not returned → billing continues
    No refunds for partial months


  25. What modulation level is considered good on PMP450?

    8x2 MIMO-B or better


  26. PoE has no light at all. What is your first step?

    Verify power / try a different outlet


  27. What frequency bands do we use for SM/CPE? Are they different across our brands (BW, DCB, XL, OpticLoop)?

    Bands used:
    5 GHz
    3 GHz (CBRS)
    2.4 GHz
    900 MHz
    By brand:
    BW/DCB: Primarily 5 GHz, others as needed
    XL: Primarily 5 GHz, some 2.4 GHz
    Optic Loop: Primarily 5 GHz and 2.4 GHz

    List of equipment we have and what frequency they operate under.

  28. When is a customer considered delinquent or late on their payment?

    Billing Cycle
    - We bill on the 1st of the month, the client is late if they do not pay by the 11th of the month and they are delinquent if they haven't paid by the 13th of the month.


  29. Customer says internet is slow every evening around 6-7PM. What is the likely cause?

    Network congestion
    Customer network or
    AP / sector congestion
