Cox Phoenix Switches to DSG Mode for Cisco Tuning Adapters

Cox Phoenix updated my Cisco Tuning Adapters this morning from using Legacy OOB mode to the newer DSG (DOCSIS Set-top Gateway) mode.
Old Firmware was FLASH: STA1.0.0_1520_LR_F.2001
New Firmware is FLASH: STA1.0.0_1520_BDSG.LR_F.1601

It looks like it's one step forward, OOB to DSG, but 2 Firmware revisions backwards. Moving from F.2001 to F.1601
F.1601 had a tuning request failure issue that was resolved in F.1901

The Diagnostic Signal Levels for OOB (FDC & RDC) are now gone, so it looks like it will be harder to do diagnostics.

There is a new Page in the TA Diagnostics Menu: "DOCSIS Information" which has the Upstream and Downstream levels.

Becky,

Would you look into why Cox chose to use an old Firmware Image F.1601 that is known by Cox, Cisco and TiVo to have a bug where tuning request failures are common and increase exponentially over a short period of time until the Tuning Adapter is rebooted.

Cox needs to update the DSG Firmware Image to at least F.1901

The bug was fixed by Cisco in F.1901 and the most recently deployed OOB Firmware Image was F.2001

Hi Bryan, there was a firmware upgrade to tuning adapters in Arizona on May 13th. I've reached out to the product managers regarding the firmware. Are your Tuning Adapters now suffering spontaneous reboots? -Becky, Cox Support Forums Moderator

Hi Bryaninphx,


We received an update from our engineering team advising us that the newest updated code is a version of the .1601 release of which has no known tuning failure issues. The .1901 and .2001 releases do not support 2 way communication which is required with our current architecture.

Latitia,

I have to disagree with your response, image .1601 did have a known bug and Atlanta Cox engineers and Cisco were aware of the issues. DAVIC or DOCSIS are both "2-way" just a different communication protocol.
