A few quick corrections I feel I should point out. A PBX is a Private Branch Exchange, or a dedicated central office (usually around 500 to more than 1,000 extensions) that large enterprises use. A Key System is one of the smaller telephone systems used by business with less than 500 telephones. NADP = No, it's the North American Numbering Plan, or NANP. In addition, I should point out that the NANP is just the numbering format standard, and not the way calls are routed. Calls are routed using Signaling System Number 7, or SS7, which is a protocol which central offices use to communicate. They use out of band data to transmit information such as the destination number, caller ID information, et cetera. The average central office in a small town serves about 5,000 lines.

telecomguy10: Also, no phone systems are not always easy to work on. There is more than just the $600 system this guy is used too. All Dmarcs on the outside of the building? Only is someone is not doing their job. Got about halfway through, couldn't stand any more. I was curious if he knew what PBX even stood for.

One small Comment about Trunk lines. What you describe is the operation of Analog lines, however even in the US for connecting a PBX digital Lines are more common. One of the Advantages of digital lines is that you do not have to setup huntgroups or alike with your carrier anymore. With ISDN and T1 lines a part of the bandwidth is reserved to communicate the called number, callerid, which of the connected channels the call is going to use, etc. This allows more settings to be made on site.

@xofuoy The "lines", Trunk Lines, represent how many concurrent calls that can be going on between people inside the building and phones outside the building. So if 4 people are on calls with people OUTSIDE the building when the 5th person tries to call OUT the call will fail (They may get a fast busy signal, or something else.) If on the other hand you have 6 people talking to other people INSIDE the building then when a person tries to call out they will be able to.

One way to look at the PBX and Voicemail is to consider the PBX as a router, and the voice mail as an "audio server" for the system

ADSL is effectively "piggybacked" onto a standard line and filtered at your premises. So if installed properly, the regular telephone side of the connection can be used for anything that a non-ADSL telephone line can be used for, including fax or dial-up computer access.

You're correct,, but only in part.. Trunks are used for that. But other places as well. It's like hearing a Toyota is a car and thinking all cars are Toyotas..
