Cisco Tuning Adapter Status Troubleshooting

Cisco Tuning Adapter Status Troubleshooting - Cisco STA1520 Tuning Adapter

12/13/13 Update: Cisco has released a new firmware that addresses tuning request failures:
The Newly Released Firmware is:
FLASH: STA1.0.0_1520_LR_F.1901 (Cox is not using this firmware, they are running F.1601)
http://www.tivocommunity.com/tivo-vb...73#post9931673
TiVo seems to have mostly fixed the Tuning Adapter request failures with SW Vers: 20.3.8
-now will retry tuning requests after a Tuning Adapter fails to respond

http://www.tivocommunity.com/tivo-vb...d.php?t=512353
Installing the Cisco Tuning Adapter:
  • Not Using TiVo's On-board MoCA networking:
    If you have a 2 Tuner Premiere or Roamio Basic (or not using the onboard MoCA on the Premiere 4/XL4 or 6 Tuner Roamio Plus/Pro) use the TA's RF pass-thru, the Cisco TA has a signal amp of about 3dB, a splitter will reduce your signal by 3-4dB.
    https://docs.google.com/file/d/0B5RO...YxRnpaNlk/edit
  • Using the TiVo's On-board MoCA networking:
    If you are using the onboard MoCA of the Premiere 4/XL4 or 6 Tuner Roamio Plus/Pro then you are best to use a splitter, the Cisco TA will not pass MoCA frequencies above 1GHz, and Cox uses the 900MHz range for the H.264 (MPEG-4) HD channels so MoCA cannot use those frequencies.
    http://media.cox.com/support/print_m...ourCiscoTA.pdf
  • Also, If you have a relatively high signal >3dBmV and don't mind the extra coax cabling, using a 2-way splitter would assure you do not loose a signal on non-SDV channels if the TA does go off-line. I find that rebooting the TA and TiVo every 3 weeks mostly eliminates the lost TA connections.

Cisco Tuning Adapter Front Panel Blink Codes

TiVo Central > Account & System Info > Tuning Adapter > Tuning Adapter Diagnostics

From the TiVo Tuning Adapter Diagnostics Menu the following value messages should read as follows, if the Tuning Adapter is communicating properly.
  • Status Summary > INITIALIZATION: Status: Ready
  • POST and Boot Results > BOOT STATUS UNcfg: Ready
  • RF Statics > DAVIC: Connected, Status: Locked
Other values you may see when the Tuning Adapter is not communicating properly are below under DAVIC

Current FDC - Current Forward Data Channel information:

Freq is the frequency to which the QPSK receiver is tuned.

DAVIC is current DAVIC connection status. Generally, under normal operation, the status should be "Connected" in a two-way environment or "Ready - B'cast Only" in a one-way environment. Most of the other states are so short that they are not visible in the diagnostic screens without refreshing frequently. Possible values are:

Red indicates a common trouble status,
Connected is the DAVIC status you want to see.
  • "Searching Chnls" indicates that the Tuning Adapter is searching for a QPSK frequency containing valid DAVIC data.
  • "Booting" indicates that the Tuning Adapter is attempting to initiate a DAVIC connection.
  • "Provisioning" indicates that the Tuning Adapter is waiting for a DAVIC provision message.
  • "Dflt Cfg" indicates that the Tuning Adapter is waiting for a DAVIC default configuration message.
  • "Slow-Boot Wait" indicates that the Tuning Adapter is waiting for the slow-boot timeout period
  • "Sign-On" indicates that the Tuning Adapter is waiting for a DAVIC sign-on message from the DNCS.
  • "Resp" indicates that the Tuning Adapter has received a sign-on request and is waiting for a randomized timeout before sending the DAVIC sign-on response to the DNCS.
  • "Completion" indicates that the Tuning Adapter has sent the sign-on response and is waiting for a DAVIC initialization complete or DAVIC ranging and power-calibration message.
  • "Calib Power" indicates that the Tuning Adapter is calibrating its QPSK transmitter's power level for optimal performance.
  • "Waiting DNCS Conn" indicates that that the Tuning Adapter has adjusted its power, received the initialization completion message and is now waiting for the DNCS to send a DAVIC connect message to establish the default DNCS connection.
  • "DNCS Conf" indicates that the Tuning Adapter received the DAVIC connect message from the DNCS, responded with a DAVIC connect response message and is waiting for the DNCS to send a connect confirm message.
  • "Conn Confirm" indicates that the Tuning Adapter received a DAVIC connect message for a connection established by an active session, has sent a DAVIC connect response message and is waiting for a DAVIC connect confirm message to acknowledge that the session's connection is ready to use.
  • "Connected" indicates that a connection exists (the usual state in a two-way environment)
  • "Data Lock Lost" indicates that the Tuning Adapter has stopped receiving valid data and will need to re-establish a DAVIC connection when it finds valid data again. May require a reboot.
  • "Ready - B'cast Only" indicates that the Tuning Adapter failed to sign-on and is operating in one-way mode. A background timer will continue to try to sign-on periodically.
  • "Unauthorized" indicates that the Tuning Adapter is not authorized to sign-on with the DNCS.
  • "Unknown" indicates an unknown state (this should never be seen).

Status is "Locked" if the receiver is locked onto a frequency with valid QPSK data, or "Unlocked" if not.
  • Level is the approximate received signal level. If the value displayed is between -10dBmV and 10dBmV, the level is acceptable, closest to 0dBmV is optimal. If the value displayed is less than -10dBmV, or greater than 10dBmV the level is unacceptably too low or too high.
  • Seconds is the number of seconds that the frequency has been locked.
  • Corr Bytes is the number of bytes received in error that have been successfully corrected by the forward error correction (FEC) code.
  • Uncor Blks is the number of data blocks received in error that were unable to be corrected by the forward error correction (FEC) code.
  • S/N (Signal to Noise) should be greater than 30dB, 40dB would be optimal.

Understanding the Cisco STA1520 Tuning Adapter Diagnostic Screens
http://www.cisco.com/en/US/docs/vide.../4025082_B.pdf

Tuning Adapter Reset:
1. Unplug the USB of the TA to the TiVo
2. Unplug the AC to the TA (not the TiVo)
3. Wait three minutes
4. Plug in the Power to the TA BUT NOT the USB
5. Wait three minutes. The TA should on it's own acquire its IP address (changes in the rate of flashing of the green led from slow to fast).
6. Plug in the USB to the TA from the TiVo

Got anything similar for Cox Motorola TA's?

Figured it was unlikely. FWIW, you sure did a nice job with this Cisco post.
