For the past few weeks we’ve had a lot of static & interference on our home phone line … it doesn’t effect the Vonage line, so I figured it was coming from outside the house.
Well, it turns out the ‘NID Splitter’ we have in the phone box is giving out. A NID Splitter is a device that plugs into the Network Interface Device that acts as a DSL filter for all the inside phone wiring. A NID is the box where the telephone companies wiring interfaces with the house wiring. Everything on the ‘Customer’ side of the NID is is your responsibility, anything on the other side of the NID is the telephone companies responsiblity.
It’s called a NID Splitter because it lets you split the phone line signal into two parts … one part that goes directly to the DSL modem, and the other half that goes to the house phone wiring. The NID Splitter filters out the voice data on the phone line so it doesn’t interfere with the DSL signal.
Here’s a few books that are getting added to my reading list. Hopefully they will be available at the library, but I think a few of them I’m going to plunk down some cash for.
I’m always amazed how many people, who are otherwise very intelligent, are willing to completely ignore hard facts and scientific evidence in favor of myth, superstition, and hearsay.
Thanks to Pharyngula for the list.
As I mentioned before … even though I’m participating in Yahoo’s Email Complaint Feedback Loop, I’m still getting deferrals when trying to deliver mail to Yahoo’s mail servers. I’ve gotten a few complaints, but not nearly enough to really justify having mail delivery deferred.
I think I’ve figured out a bit more about why Yahoo’s mail servers are deferring some of the mail my servers try to deliver to them.
While doing a little searching, I found some information on email feedback loops for other major ISP’s.
