Why I am having trouble using channel 3 on my Bose tonematch the XLR is fine but the 1/4 inch does not work


On the T1® the first three inputs are combo inputs that take both XLR and 1/4" jacks. You want to connect your guitar to the combo jack (in the middle of the XLR input). The 1/4:" jack below that is actually a line-out.

I just installed a replacement At&t EP 5962 2 line, answering answering device telephone. Line 2 does not get a dial tone. I installed it into proper / same as before outlets and both lines light...


There may be damage to the wiring of line 2 (either in the building or on the phone). Are both lines wired to one jack or are they separate? Do you have any other jacks that have line 2 connected (preferably as single line jack) in the building?

I like to use an old single line corded phone that does not use a power adapter. (As long as the EP5962 corded base will work without power (POTS), it might work for the tests below. You might want a simpler phone to carry around.)

If the lines have separate jacks, try switching line 1 and line 2. (Connect your Line 2 jack to the Line 1 input on the phone and vice versa.) If line 2 doesn't give a dial tone when connected to line 1, see the next set of tests. Otherwise, contact AT&T if the phone is under warranty. These phones are not meant to be user-serviced. Alternatively, plug in a different phone to the line 2 jack to test for dial tone.

Next move to another jack with line 2. Check if you have dial tone at that point. (If you do, you know the problem is at the first jack or the wiring to the jack.)

If there is no dial tone at the next jack or you do not have another jack for the line, find where your telephone service comes in. Open the service box and determine the type of connections in the box. If you are lucky, you will find RJ-11 jacks for the incoming service. Plug in your test phone and check for dial tone. If you have no dial tone or can't check the service, then contact your telephone company. They will test your line and fix it free if the probIem is outside.

If you have a dial tone, then it's an inside wiring problem. Inspect the visible wires for damage. Open the faceplates for the jacks and check for loose wires. There are two types of connectors. Screw type connectors need the wire stripped back a little then wrap around the screw and tighten. The other type is a punchdown jack. To repair a loose wire in this, you will need a punchdown tool. These are often available in hardware/home improvement stores in the wiring section. http://www.lanshack.com/wire_phone_jack.aspx has clear pictures of the wire color to pin pattern.

You may want a professional to check the wires inside the walls. Your phone company will fix problems for a fee.

Damaged DSL filters on one line could be the cause. Similarly certain animals may have chewed on the specific wires somewhere in the line.

I hope this helps.

All of the lines are steady red, which means the line is in use by another set. However, no other phone is using those lines. Can you shed some light on what I need to do.


You need to find where your phone line has a problem. This could be a sign of a wiring problem inside or outside or a problem with the phone itself. First try another phone at the current jack (I prefer to use an old corded phone with a different phone wire). Since this is a 4-line phone, you will need to check each line separately. Check for dial tone. If the test phone works, try the second wire with the ATT-974. If it still doesn't work, replace the phone. Modern phones aren't meant to be user fixable. If neither phone works, continue below.

Next try both phones at a different jack. If the phones both work and the jack is for the same line as one of the lines to the first jack, then you probably have a wiring problem at the jack or leading to the jack for all of the lines. You can open the faceplate and check for loose wires. If it is the wires to the jacks, you may want a professional to deal with the issue.

If you get the in use message at other jacks on both phones, find where the telephone service comes in. If you are lucky, that will terminate in RJ-11 jacks. Then open the service box and use your test phone there. If the problem occurs at the service box, call your phone company. They should fix it for you. If the dial tone is normal, it's an inside wiring problem. The phone company will fix it for a fee. (If the service uses a non-RJ11 jack, you should have the phone company do this test.)

I hope this helps.

(who has gotten a line in use error when mice chew on the wires or a crew dug too deep near the underground wires. Sometimes we'll hear a fast busy signal when the handset is picked up with the problem. Although with 2 line service, only the digging humans usually cause a problem with both lines. Animals only damage on line at a time outside.)

DECT 6.0 home phone doesn't ring after switching to u-verse/voip


Have you tried to plug the base unit into a different phone jack to see if it might just be that outlet. You may have a short in that particular phone jack or a loose wire there.

Good Luck.....

Need help wiring new pressure switch for craftsman air compressor


Assuming that you are wiring for 115v. Lets start with the ground. The cord that attaches to the wall outlet will have three wires, green, black , and white. Insert the cord thru one of the openings of the pressure switch and attach the green wire to the ground screw. Next look very closely at the contacts and notice that they are arrainged in pairs. There is a small brass bar with two contacts that completes the circuit for each line. Start with L1 and attach white wire from cord, then attach white wire from motor to the screw terminal that small brass bar bridges to (should be T1). Next attach black wire from cord to L2 and black wire from motor to remining screw. Remember that the small brass bar with two contacts is the bridge and simply connects white to white and black to black. Enjoy

I have 3 phone jacks in my home and right now on one of them gets a dial tone. The other two are completely dead. What could be the problem?


There should be a termination point outside your house where the local phone company connects to the wiring inside your home. These are usually wired for at least two phone lines. Sounds like your house was at one time wired for two numbers and the jack that is working was on one number while the other two jacks were on a different number. Best thing to do is connect all three jacks to the working telephone line outside the house. Good Luck. ...Mike

Going wireless with a T1 Line


Going wireless should not be influenced by the nature of your internet connection. Here, I will assume that your definition of "standard router" is the kind of router we can buy at any electronic store (DLink, Linksys). I you are think more about a high end router such as a Cisco 2600 or 2800, please post a comment and I will adjust my answer.

If you already have internet access through your T1 using a wired network, you may just add one (or more) Wireless Access Points to your existing network. No need for a router here since you already have one for connecting the wired network.

On the other side, if your T1 line will be dedicated to your Wireless access, then a router should do the job. Usualy a T1 line uses a static IP address on the WAN side. If your Wireless coverage required more than one Access Points, then I would suggest you to use a standard router (no Wifi) with seperate access points.
