Hello

I know that the following things have been discussed at length in these forums, and I have read the threads but still have questions.  I have Blast Pro speed with Voice.  I am still using a 722G which I know is not capable of Blast speeds.  Here are the stats after a manual reboot:

Downstream

  DCID Freq Power SNR Modulation Octets Correcteds Uncorrectables
Downstream 1 13 615.00 MHz 1.70 dBmV 36.84 dB 256QAM 93496604 0 0
Downstream 2 14 621.00 MHz 2.23 dBmV 37.09 dB 256QAM 96757192 0 0
Downstream 3 15 627.00 MHz 2.28 dBmV 37.09 dB 256QAM 96710392 0 0
Downstream 4 16 633.00 MHz 1.88 dBmV 37.09 dB 256QAM 96888026 0 0

Upstream

  UCID Freq Power Channel Type Symbol Rate Modulation
Upstream 1 1 30.10 MHz 42.25 dBmV DOCSIS2.0 (ATDMA) 5120 kSym/s 64QAM
Upstream 2 4 23.70 MHz 42.25 dBmV DOCSIS2.0 (ATDMA) 5120 kSym/s 64QAM
Upstream 3 3 17.30 MHz 42.25 dBmV DOCSIS2.0 (ATDMA) 5120 kSym/s 64QAM
Upstream 4 2 36.50 MHz 42.25 dBmV DOCSIS2.0 (ATDMA) 5120 kSym/s 64QAM

 

The reason I still have this device is that I do not like the all in one units.  I like to have more control and use separate devices for each purpose.  I could not get the latest Comcast unit to stay in bridge mode, so it was returned and I reinstalled the Comcast owned 722G.

 

Here are my questions:

1--Based on the signal strength, could my line support a splitter to send the Voice signal to the 722G (or some other comcast device.) and Internet to another modem--perhaps a Motorola MB8600 or MB7420?  Does Comcast even allow this?

2--Is it possible to configure Comcast Voice to auto-forward all calls to another number and eliminate the need for an EMTA capable device?

3--Does anyone know of a stand alone Docsis 3.1 EMTA device?

4--Does anyone have updated information on the firmware updates that are being pushed out?  Do the units stay in bridge mode?

5-Does anyone like the retail combo units--Netgear-700V or Arris SVG2482AC?

 

Thank you, for any and all input!!

Unless you really want a DOCSIS 3.1 capable device, you could use a DOCSIS 3.0 Arris TM822 for Blast 200 Mbps. It is not a combo gateway device.;

Your signals seem strong enough to split the line and use an internet only cable modem along with your 722. You would need to call them and tell them what you are doing. You would need to have the 722 activated for phone service only and have the internet cable modem activated for internet.

Thank you.  I considered that unit.  My local office does not seem to have it in stock, and the 822R is priced about the same as the newest Motorola unit.  It also appears that some folks have issues with the voice part of the unit. My issue is not with the monthly modem fee as much as it is with wanting speed plus stability.  (and future proofing, whenever possible.)
