Re: McKinney Connection drops and lots of uncorrectables over a few day period

power adapter is pluged in downstairs and connected to a coax up to the service panel box and plugged into the power coax port.  No battery on the EMTA.

You have the amp  with out the center power port, correct?

yes

OK, can you tell which port the modem is on? If it's on the VOIP, change it to one of the spare ports, Hopefully there are terminating resistors on the empty  ports, when you take it off, put it on the now open voip port.

 Next step is to recheck levels.

Making you a drawing...This will raise the downstream level by 3.5 dB and lower the upstream level by 3.5 dB

The modem will lose signal when AC power to the amp is lost unless you get it to a UPS

The term resistors are important, especially on the now unused VOIP port... The modem and terms can go on any of the 8 "output" ports

I like... Okay i will try this, this weekend.  finger crossed.

Re: McKinney Connection drops and lots of uncorrectables over a few day period

All of the coax is RG6, correct? If there's rg59, that would explain the rolloff and it's typical, the lower s/n as freq goes up and power level drops  indicate lossy cable, could be damaged, or wet as well as too small a diameter, like a long outdoor run of rg6 when rg11 should have been used. Badly crimped connectors are also an issue, they need to be replaced with compression ones

 

Levels need to be measured at the street tap off then at the grounding block, amp in and outputs then the modem.

here are my new reading as of today, not looking much better.  Where is the grounding block?  is that at the tap?

Re: McKinney Connection drops and lots of uncorrectables over a few day period

This channel is being interfered with by one or more of an old 800 cellular "wireline or non wireline" carriers subscriber handset.

 

 this indicates ingress from a corroded or broken shield somewhere.

Re: McKinney Connection drops and lots of uncorrectables over a few day period

The grounding block is the required ground bond to your house  electric/ telco ground point where cable enters the house, from either an overhead or underground drop  .

It is where the "To street" connection on the amplifier is connected.

Is there a twc grey box out there? What's in it?

 I don't see any level changes from the modem line that you were going to change ports on last weekend.

You either moved the wrong cable or there's an amplifier issue
