CDV TOO Loud!!

Frequent Visitor

CDV TOO Loud!!

I just moved from Comcast Digital Phone to CDV.  The earpiece audio I hear via CDV is WAY TOO LOUD (CDP was perfect).  I have adjusted all of the phone volume controls to the lowest setting, but it doesn't help.

I called Comcast Tech Support and they stated this could be adjusted via the cable modem. But when the Tech Service guy arrived, he stated there is nothing that can be done.  He exchanged the cable modem, but it didn't help.

Is there anything that can be done?  (Besides putting a piece of ScotchTape over every earpiece of every phone)

If it matters, my service is from the Rolling Meadows, IL office.

Re: CDV TOO Loud!!

Just wondering if there is a solution to this problem? I also have my phones on low and still the volume can be loud enough that I have to hold the phone away from my ear. A tech checked when he came out to put batteries in my modem that, I discovered after a power failure, were never installed and he said there was nothing they could do about the volume.

No issue here.  Are these corded or cordless phones and all the same type or different ones?

Re: CDV TOO Loud!!

Thanks for the reply GDM Husky

Three phones. Two corded. one cordless and the volume is loud on all. Three different manufactures also AT&T, Panasonic cordless and cheap Southwest bell.

Comcast replied also (thank you) and said my line levels were great and there was no problem at their end. This is not a MAJOR problem, I just have to hold the phone a little away from my ear but I just wondered if anyone else had this problem and perhaps found a solution.

Nope - There was no resolution from Comcast.  They did not have an answer for the LOUD volume. 

For me it is a big problem.  Holding the phone away from my ear makes the caller sound too tinny.  For the really LOUD calls, I'll curl my fingers over the earpiece just to cover it up (which, of course, lowers the volume).

This happens on corded phones and cordless phones.  I have an old Panasonic corded, and a new Panasonic cordless and an old Ma Bell wall phone. All are the same.

Comcast Digital Phone worked really well for me and CDV has been very aggravating.   At then end of the promotion (when my monthly fees go up) I plan to find something that works better.

Re: CDV TOO Loud!!

rice & murf,
 
What happens if you plug a phone directly into the back of the modem?  Is it still loud?
Contributor

Re: CDV TOO Loud!!

GDM
Tried plugging directly into modem and still loud. Since posting I have noticed today that only some calls are really loud to the point I have to hold it away from my ear. Others are still loud but not uncomfortably. As I told the Comcast rep, when I had AT&T all of my phones were set to either their highest volume or close to it. Now they are all set to the lowest.

Re: CDV TOO Loud!!

Do you have the eMTA?modem plugged into a surge protector?  What's near the eMTA/modem?  I wonder if anything is interfering with the modem/eMTA.
Contributor

Re: CDV TOO Loud!!

Yes it is plugged into a surge protector and it is near an apple extreme wireless router. After you asked the question I moved the router further away with no effect. I was only able to move it a few feet due to length of wire so I tried unplugging the router also with no effect. Should I try not using the surge protector?

Re: CDV TOO Loud!!

I just remembered that I also have a signal amplifier that was installed a number of years ago by comcast for my TV reception. It is an EDA 2100 Drop Amp. It is out in my garage where the cable enters the house. Don't know if this could cause any problems or not.

Re: CDV TOO Loud!!

I don't know enought about cable itself.  Maybe the amp is causing some thing with eMTA.
 
That was my thought with the router and maybe a surge.  You could try unplugging it completely since it has a 8 hour battery backup and test the phone then.  If it's not that then maybe it's the amp in the garage.
Contributor

Re: CDV TOO Loud!!

Tried unplugging the modem with no change. Unfortunately, without rewiring my house I can't get rid of the amp so I guess I will just cope. My problem is not as bad as the starter of this thread.

Thanks for trying to help GDM-Husky

No Problem sorry couldn't find the issue.

Re: CDV TOO Loud!!

Hello ricelewis,
In regard to the high volume that you’re experiencing, it’s likely the problem may be with your handset, although I do have an idea that we might test. I will be contacting you again very soon to discuss some of those possibilities, or if you prefer, please feel free to contact me first.
Thanks for posting!

Hi murf26,
I’m sorry that I didn’t see your original post back in February of this year. I simply was not a moderator at that time. If you could please email me with a
time that I can contact you directly, we might be able to resolve your call volume issue.
Thanks for posting!

Re: CDV TOO Loud!!

Hello all.

Quick question and comment:  Has anyone here ever directly experienced interference in their cable modem/eMTA from a router? I mean, not just reading of it or hearing about it on a forum but actually seen or had it happen to them?

Frankly I don't believe that this is a common issue -- if it is even a real issue at all. I have not found any instance of someone actually experiencing this problem, though I have seen numerous posts - mostly here - mentioning this as a potential cause of just about every eMTA problem ever reported here. I honestly beloeve that, though I cannot definitively rule out the possibility of such interference being possible, I think the probability of such interference causing volume or connectivity problems is about as infinitesimal as it could possibly be.

In the last two days I had continual but intermittent interruptions in my eMTA's connectivity (after hearing about every possible cause, it turns out that Comcast Maintenace was performing scheduled maintenance on my node!!), and I had occasion to ask two senior/supervisory support techs, one CDV specialist who was out to check my eMTA, and two Maintenance employees - a supervisor and a senior tech, if such router to eMTA interference could possibly cause connectivity or other performance problems. All commented almost identically -- they have never seen evidence of such interference, none would ever recommmend moving the two pieces of equipment apart distance-wise, and all said that they do not believe such interference is a possible cause of connection or any other modem/eMTA issues.

So is this truly a theoretical potential? Or is it one of the many internet rumors/hoax concepts that seem to take on a life of their own?

Thanks,

Re: CDV TOO Loud!!

Personally my router is next to the eMTA.  I can tell you from DSL certain routers and modems didn't always play nice together.
 
I would assume the same thing could happen with the eMTA with certain routers.  Overall I would think it's a small percentage compared all routers.

Re: CDV TOO Loud!!

GDM:  I agree that equipment sometimes doesn't "play nice together" - actually quite often! But that is not to say that there are interference issues between them. I have encountered a number of interference issues particularly with RF, but never saw any between routers and modems. It has always been a different issue.

Re: CDV TOO Loud!!

I would agree about the RF typically that is the case.  For DSL modems many things have causes issues.  Dimmer switches, flourscent lights, etc.
 
The cable stuff is new to me so I can't say.  I have tried 5 different routers since I got CDV and none of them have affected it.

Re: CDV TOO Loud!!

Dear J-Mac,
 Approximately two years ago, maybe longer, the first confirmed report of router interference occurred. A customer in the Indiana area reported that his calls were dropping; he had call volume problems, and was reporting a loss of dial tone. Finally, after seven technicians had visited the house and checked for problems, the last technician replaced the wiring. The problems continued; then a field supervisor, a lead technician, and a line technician went to the house and discussed with the customer what had already been done, and what they possibly could have missed. They were looking at the connections in his computer room, and eventually determined that the only step that had not been tried was to move the wireless router away from the eMTA, which was actually sitting directly above his modem. They decided to move the router about 10 feet away from the eMTA, and then they left it alone for about a month, with the customer’s permission of course. The result was that this small change resolved the issue! Yes, I agree it could have been something else, but since they made that small change there has not been a single repeat call. I have also spoken with a number of other customers that have had the same type of issues, and once they moved their router away from the eMTA, the problem cleared up. Granted, this is not the “be all to end all” solution, but it does need to be considered when troubleshooting this type of problem.

Thanks for posting your question,

Re: CDV TOO Loud!!

Hi Jim.

Jim, RF signals cannot interfere with the eMTA, period. Please consult with a Comcast engineer about that. There is no wireless functionality associated with the Arris eMTA.  Of course, RF signals can definitely interfere with the wireless router!  Since you do not mention the router brand, model, firmware version, and other factors, such as other RF-wireless equipment in the house, etc,. I could not even speculate what specifically is more likely to have been causing that customer's problems. But I can definitely say it was not RF interference from eMTA to router or vice versa!  If moving the wireless router did indeed appear to eliminate the problem, then there most likely was an interference issue, but it was never between the eMTA and router.

Could have been a cordless phone (2.4 GHz only -- or I have seen some 5.8 GHz cordless phones where the cordless handset transmits at 5.8 but receives at 2.4.  Or maybe vice versa.); microwave oven - only when the magnetron is running of course; wireless gamepad - if 2.4 GHz; mobile phone -- many have a cradle to charge and data-connect cell phone to PC and it is sitting right next to the router; all Bluetooth devices - headset, cellphone, keyboard, mouse, etc.; a municipal wireless network - usually a very high-powered transmitter send a net over a neighborhood (These have been wreaking serious havoc with those using wireless networks at home!); even a lot of lightning - at least the kind known as "fusion lightning".

Basically one or more of any of the above-mentioned items - and more - could have been interfering with the wireless router. But the eMTA cannot do that. Just as the wireless router cannot cause interference that would affect the eMTA. Unless someone has discovered a whole new type of RF interference that is either generated by a non-wireless eMTA, or can interfere with a non-wireless eMTA.

I'm not just trying to be contrary. But anecdotal instances such as you relate in your post are what helps to propagate wrong theory. I still have yet to see a case of this so-called cable modem <---> wireless router interference documented by anyone who both witnessed it and knows about RF/WiFi theory.

Re: CDV TOO Loud!!

I am having the same problem. The volume on my phones are turned all the way down but I have to hold the handset away from my ear. These are the same phones that I used with Qwest and did not have a problem. I tried using different phones with the same problem.

 

I tried to speak to a CSR about it was was promptly told that it was a problem with my phones. He did not seem to want to listen to me try to explain my issue and continued to insist that it was my problem. He told me that he would send out a tech but when he determines that it is my problem I will get charged. It seems that I am not the only one with this problem. I just want to know if there is any way to lower the volume from the eMTA. I noticed that one of the moderators seemed to have a solution for another user. Any help is appreciated.
