• Make sure the ringer volume on the phone itself is turned on and up.

• The Network Interface Device (NID), also referred to equally the Subscriber/Network Interface (SNI) or the Signal of Demarcation (Demarc), is the box, often grey and usually on the outside of the structure, where the telephone company'south wires kickoff, the lightning protector is installed, and your phone wiring terminates. (True to phone company tradition, the terms "NID" and "SNI" are pronounceable acronyms -- they are ordinarily spoken every bit "nid" and "sny" rather than "northward.i.d." or "s.due north.i.") An of import feature of the NID is a test jack with a short phone string. Unplugging this string disconnects all of your internal wiring from the telephone company's network, assuasive you to plug a "known-good" phone into the NID to verify that the service is working up to your dwelling or business. If information technology is, your "service" is fine but your wiring or a device inside are causing the problem. (See line lockout, below.)

• Telephone companies often offer a "wiring maintenance" program. This plan covers repairs to wiring that meets their standards only has become defective. More than importantly, this plan prevents you from having to pay "nonproductive dispatch" charges if the technician finds that the trouble is inside your house. Or, to exist more precise, if the technician does not find any trouble outside your firm (i.e., the dial tone is skillful up to your network interface). This is substantially extortion coin, only is better paid than not paid: you're paying the telephone visitor to shut up, be nice, and help you lot when you take trouble. Your reward is no finger-pointing.

• Line lockout can trip you up when troubleshooting. When your telephone line is left off the hook for more than a couple of minutes, the phone company central role switch automatically places your line in "lockout." This prevents your line from consuming resource that might event in denials of service to other customers. Many faults in your telephone wiring or equipment will crusade the central function equipment to act equally if your phone is really off the hook. When this occurs, your line goes into lockout. The troubleshooting implication is that your line may not clear for several seconds after yous discover and remove the crusade of the problem.

• If a phone stops working after a thunderstorm, it's possible that lightning striking the phone line and caused a voltage surge that damaged the phone. The actual hit could accept occurred several miles away, and traveled downwards the line to your telephone.

• Home and small business organization phone wiring is unremarkably installed using ane of these topologies:

  • Star or Habitation Run - each jack has a wire running back to the NID.
  • Daisy Concatenation - wires from the NID go from ane outlet, to the next, to the next. (This may as well be called a "ring" topology, except that it is non a true band, since the last outlet doesn't loop effectually then go back to the NID.)
  • Combination of the two - You may discover a spur subtending from a indicate along a daisy concatenation, or that some outlets have a dwelling run back to the NID while others are part of a Daisy Chain

• If a phone won't dial out, make certain that there isn't a tone/pulse switch set in an incorrect position (such as midway between the ii positions). Notation that pulse dialing won't work if you are using some VoIP services, and tone dialing won't piece of work on some telephone lines (although this is no longer a mutual occurrence in the United states of america).

• Working on phone wiring during a lightning storm can exist fatal. Telephone wires become exterior. Whether above ground or surreptitious, they still are all vulnerable to lightning. The telephone company adds lightning protection devices outside, but the chief purpose of these devices is to protect their network from indirect lightning strikes (where lightning strikes near simply does not actually striking the lines. A directly hit can start fires, plow your telephone or outlet black, and possibly kill you if y'all are holding the telephone or working on the wires. If yous need to be speaking on the telephone during a lightning storm, you should use a cordless telephone or a speakerphone -- hardwired phones can bring the lightning from outside all the manner to your ear.

• An industry slang term for ringing voltage is "jingle juice." You will but need to affect the wires or internal parts of a ringing phone once in order to empathise this. Y'all can receive a very annoying, though usually non fatal, stupor while working on telephone wiring, peculiarly if the telephone rings or is dialed (in the case of a rotary dial/pulse telephone) while you are touching the wires. The daze will be exacerbated if you are continuing on an uninsulated or wet surface, if you are touching both wires at the aforementioned time, or if whatever other part of your torso happens to be touching a grounded metal object -- such a pipe, conduit, deep freeze, etc.
