NOTE: Software
version 17.12.1y for the cBR-8 has been extensively tested
with ServAssure NXT
Upstream Spectrum. For the best experience with Upstream
Spectrum and Upstream Spectrum Capture, 17.12.1y is the
preferred and recommended version. | ||||

- The port ifIndex is missing for the cBR-8 UTSC PNM file in versions 16.9.1 through 17.3.1. This can prevent ServAssure Collection Platform from selecting the correct FFT file, causing Upstream Spectrum to fail. To work around this issue, upgrade the cBR-8 software to the recommended version, 17.12.1y.

PNM actions on Cisco CMTS devices may time out intermittently, as a result of the TFTP file being sent to incorrect destinations. This affects ServAssure NXT CmtsRxMER per subcarrier, when performed with modems on a Cisco CMTS. To work around the issue, upgrade the cBR-8 to the latest firmware then retry the PNM action. Multiple retry actions may be necessary.

After a period of Upstream Spectrum captures, the RMD may stop sending static pseudowire L2TP data after a successful SNMP triggering of an UTSC test.
To work around this issue, restart your RMD.
To resolve this issue, contact CommScope Technical Support to upgrade your firmware version.
Severity: Major
First occurrence: ServAssure NXT 2.12
- NXT-22139/CCAP-3066
When multiple Upstream Spectrum captures are triggered on the same RPD on a E6000, the RPD may get stuck in a busy state, not allowing new captures. When this happens, user sees the error, "Timeout occurred, waiting for CMTS upstream port to be available," for 5-10 minutes, until the CMTS is no longer showing the busy state on the RPD port.
In ServAssure NXT 2.12 and above, the product is changed not to allow concurrent US Spectrum captures on an RPD.
Severity: Major
First occurrence: ServAssure NXT 2.12
- NXT-21257/RPD-6342
An RD1 Series RPD defect exists that when ServAssure NXT triggers a static pseudo-wire UTSC on one port, any active L2TP session on the other port immediately stops and no L2TP data is received.
In ServAssure NXT 2.12 and above, the product is changed not to allow concurrent US Spectrum captures on an RPD.
Severity: Major
First occurrence: ServAssure NXT 2.11
- NXT-20120/RXDSW-12884
On CommScope RMDs running a firmware version prior to DAA_V04, Static Pseudowire can be blocked due to a firmware bug that causes the RMD L2Bridge Forwarding Table to not clean up properly. When this table fills up (64 entries), the RMD can no longer create new L2TP connections, causing ServAssure NXT Upstream Spectrum Analyzer to not work on the RMD.
Contact CommScope Technical Support to upgrade RMD firmware to v3.2 or 4.0 and above.
Severity: Major
First occurrence: ServAssure Collection Platform 2.10
- NXT-22648/RXDSW-13600
After successfully initiating a static pseudowire Upstream Spectrum Capture on a RMD in IdleFFT mode, the RMD does not send any data back to L2TP Receiver.
To work around this issue, switch to Freerun mode.
To resolve this issue, contact CommScope Technical Support to upgrade your firmware version to DAA_V04.00.00.0121 or higher.
Severity: Minor
First occurrence: ServAssure NXT 2.12
- NXT-22646/RXDSW-14502
The RMD may intermittently stop sending static pseudowire L2TP data.
To work around this issue, restart your Upstream Spectrum capture.
To resolve this issue, contact CommScope Technical Support to upgrade your firmware version.

- US Spectrum Analyzer shows an IdleFFT graph with a small frequency shift when the chosen center frequency is not a whole mega hertz (MHz) value. This affects the following devices:
- RD3 Series RD2322 RMD
- RD3 Series RD2322 RPD
Severity: Minor
First occurrence: ServAssure NXT 2.11
- PROD00275644
When running CMTS Upstream Spectrum Analysis in Standard mode (i.e. UTSC mode) on E6000 CER Version 11 or earlier, the CMTS may start to report SNMP errors on
DocsPnmCmtsUtscConfig/DocsPnmCmtsUtscCtrl tablesafter continuous spectrum analysis. This causes Upstream Spectrum Sessions to fail after running for a while. Contact CommScope Technical Support to upgrade to the latest firmware.Severity: Major
First occurrence: ServAssure NXT 2.7.1
- PROD00266073
An E6000 CER defect exists wherein the E6000 CER generates the UTSC binary file using a frequency domain format when a timeIQ format is required.
Severity: Medium
First occurrence: ServAssure NXT 2.4
- PROD00265957
An E6000 CER defect exists that can interfere with events reaching the ServAssure NXT user interface. A fix for this defect is planned for E6000 CER release 9.0.

Compatibility mode is not supported in R.13.
- RD2322
- Compatibility mode is not supported on RD3 Series RD2322 RPD or RD3 Series RD2322 RMD. To work around this issue, use Standard mode in Upstream Spectrum Analyzer on E6000 CER channels.

Casa CMTS devices offset the central frequency of the tone by 0.12MHz, or 1 bin size.
Severity: Minor
First occurrence: ServAssure NXT 2.7.7
- NXT-15078/Casa 161340
Casa CMTS devices do not set a filename in MIB when running UTSC capture on R-PHY freerun mode. This can cause ServAssure NXT Upstream Spectrum Capture to fail when freerun mode occurs on a Casa R-PHY upstream channel.

Other device-specific known issues
- NXT-14562
Some Hitron modems use a different value type than what is listed in the standard DOCSIS MIB for the critical OID
docsIf3CmSpectrumAnalysisCtrlCmdInactivityTimeout(1.3.6.1.4.1.4491.2.1.20.1.34.2). DOCSIS specifications indicatedocsIf3CmSpectrumAnalysisCtrlCmdInactivityTimeoutuses the type "Integer (32bit)", but older Hitron modems expect the type "Gauge (32bit)". This mismatch causes the Virtual Spectrum Analyzer in Alarm Central to fail for those cable modems. To work around this issue, upgrade your Hitron modem to the latest firmware version.Severity: Minor
