Key Diagnostic Information DOCSIS TX Description: Upstream DOCSIS transmit RF level. Two way communications protocol. 1st Generation Cisco 86xx / 46xx series set-tops with DSG capability. Why it’s important: High transmit RF levels may indicate excessive losses in the home, HFC plant alignment, or MTC/STC location. Technicians must troubleshoot excessive loss by verifying tap transmit levels and calculating drop return spectrum loss.

Key Diagnostic Information DOCSIS RX Description: Downstream DOCSIS receive RF level. Why it’s important: This specification is within DOCSIS parameters and considers total composite power. Hi / Low levels indicate plant issues or issues within the drop network.

Key Diagnostic Information DOCSIS SNR Description: Downstream DOCSIS Signal to noise ratio (qualitive performance measurement). Why it’s important: Low SNR indicates noise issues in the plant / drop network. Overdriving amplifiers with high RF can negatively impact this metric.

Key Diagnostic Information Pre FEC Description: Downstream Bit error count prior to Reed Solomon error correction. Indicates bit errors in the incoming data stream. Why it’s important: Pre FEC errors indicate impairments with the incoming data stream. While no errors are preferred, small numbers can be tolerates as long as the post error count is the equivalent of 0 errors.

Key Diagnostic Information Post FEC Description: Downstream Bit error count post Reed Solomon error correction. Indicates bit errors FEC unable to correct. Why it’s important: Post FEC errors indicate that errors in the data stream are so severe that the error correction algorithms cannot adequately correct. Customer will have noticeable issues when this occurs.

Key Diagnostic Information Uncorrectables Description: Downstream Bit error count post Reed Solomon error correction. Indicates bit errors FEC unable to correct. Why it’s important: Indicated issues with the RF performance.

Key Diagnostic Information Version Firmware Description: Displays the current loaded software version. Why it’s important: Good reference information.

Key Diagnostic Information CMTS Upstream Description: CMTS Name and associated upstream port designation. Slot / port / US carrier. Why it’s important: Verify that the upstream digitally modulated carrier amplitude at the input to the CMTS upstream port is within spec.

Key Diagnostic Information CMTS Downstream Description: CMTS Name and associated downstream port designation. Why it’s important: Downstream data is transmitted over the CMTS downstream channel.

Key Diagnostic Information T 1 – T4 Error Count Description: Number of timeouts caused by the CM not receiving a valid UCD, receiving broadcast ranging opportunities, RNG-REQ message, or unicast ranging opportunities from the CMTS. Why it’s important: This may indicate downstream frequency signal issues, not receiving maintenance opportunities from the CMTS, not receiving a response (RNG-RSP) message from the CMTS, or a temporary loss of service.

Key Diagnostic Information MoCA Node TX Gcd Rate Description: Also known as MoCA PHY Rate. The total RF power of a given node MoCA frequency 1150 MHz transmit power in dBm. Why it’s important: To convert dBm to dBmV add 48.75 to dBm measurement.

Key Diagnostic Information TX Unicast Phy Rate Description: Throughput rate in MB/s from current node to the node indicated. Why it’s important: Transmit rate from the local node to each other node in the network.

Key Diagnostic Information CMTS Rx Level Description: The RF input level as recorded at the CMTS return input card from the DOCSIS transmitting device. Why it’s important: Verifies that the power is set to the level commanded by the CMTS.

What is a Watch? A Watch gives you the ability to take a snap shot of the customer’s system over a period of time. Why it’s important: Scheduling a Watch will help you diagnose intermittent problems.

Scheduling a Watch Choose the Start Date. Choose the Number of Days to run the Report. Choose the Time of Day to run the Report. (One choice is already active, click the check boxes to schedule up to 3 more time frames) Animation: After saying “click schedule watch” click the mouse and the calendar will appear. Click again after saying “click save” and the Watch list appears. Click Save Click Schedule watch

Viewing a Scheduled Watch Animation: After saying “Click Reports” click the mouse and the reports windows appears. To view a scheduled Watch click Reports. A new window appears. Click Scheduled Jobs Summary.
