CBR-T Manual

I recently upgraded my service and I have this new CBR-T wireless router.  When first installed I did not have time to reset all my rules from my old router so I called support to get a manual on the modem.  They asked what I needed and they switched the modem to passthrough mode.

 

I now want to use the new modem as my router/wireless device and I cannot locate a manual for this device.  I would like to be able to put it in passthrough mode, take it out of that mode, etc.  I would like to manage the device.

 

All the help pages I've found reference the modem that was replaced.  Can anyone help me locate a manual for this device?

Re: CBR-T Manual

Dear Comcast:
!PLEASE! Join the rest of the civilized tech world and post the manuals for your nerworking hardware online!

I'm helping a relative setup the network at their business.
They have a CBR-T gateway, and the Artista C-75 device for their WiFi Pro service. We need an actual *manual* for both that we can download, not an over-simplified quick guide that basically says "plug it in, press the button, and pray".

Neither of us wants to wait on hold to speak to Comcast support every time a question comes up about the settings available for these devices, or how to configure them to do what your customer wants it to do.

I find it strange that on your support forums, the majority of the responses from Comcast support to customer posts about technical questions seems to be something like:
"Sorry to hear you're having problems. Send me your account info in a private messaging session..."
Any actual, useful info that might be provided apparently stays down that private rabbit hole, so none of your other customers can find it. This runs completely contrary to the concept of support forums as a resource to find useful info, creating instead, a place to see a large collection of similar, unhelpful, apologetic responses that contain almost no info on the actual issue, or its resolution.

Re: CBR-T Manual

Hi, there @LuckyStiff63, and thank you for sharing your feedback. I understand why the lack of information available regarding the modem manual could be frustrating and want to help provide the information you need if you haven't located it already. Were you able to find the manual information for the CBR-T gateway and  Artista C-75?

Re: CBR-T Manual

Thanks for the reply. I was able to find manuals for both items online, but given that manufacturers often modify the hardware and/or firmware of the devices they produce to meet their customers specs, we can't be sure that information taken from manuals we find online actually applies to the physical device we have.

One issue lspecific to the C75 manual that I was able to acces, was its extremely limited info on how to access the configuration settings using either the "console" port, or while wired into a CBR-T gateway. Connecting through the console ethernet port requires a swap / crossover cable, but there is no indication of which specific IEEE
"swap" wiring method isnrequired. There are several variations of pinouts for 10/100 and 1000kbps cables, with and without POE. And if we do guess the proper swap configuration, the manual doesn't give any specifics of the SSH connection configuration requirements. Secure SSH is not usually "plug and play", so without the proper settings, connecting to the C75 via the the console jack isn't likely to happen.
Any help or info you can offer here is greatly appreciated, and will likely save someone else's day in the near future.
