I've worked at places where the multiple line analog phones use that type of connection to carry all several phone lines into a common phone. It's probably not what that is, but at the same time I wouldn't go plugging a computer network cable into the "V" part of that without knowing for sure what it is. Ringing voltage on a regular phone line can be up into the 100 volt range. It could do interesting things to a computer network card. -- Please note this e-mail address is a pit of spam due to e-mail address harvesters on Usenet. Response time to e-mail sent here is slow.

Maybe, just maybe-it was left over from the days before wireless and they chose nit to rip the plate out of the wall? Whatcha think?!?

It's an Ethernet connection. If it is active you can connect your Mac to it via an Ethernet cable and connect to the Internet. Some have said that it is from the days before wireless. Perhaps. But my library branch has ethernet plugs such as the one you depicted, all left over "from the days before wireless," and all fully functional. There's only one way to find out if the connection is active, and as you have learned, it has nothing to do with the library staff. There is probably one IT person for your entire library system and he may be a contractor; it wouldn't be efficient to try to track that person down and ask them about the connector. Just plug in. > What else would i have to do to get it to work...??? Nothing. That's why you use a Mac. OK -- maybe one little thing. If it doesn't connect automatically, go to the Network Preference Pane and ensure that Ethernet is turned on. I keep my Ethernet turned on at all times, and when I plug into a new network at a hotel or the library &c. it just works.

Assuming you're referring to the jack at the lower left, it could be any of the things in this list, at least; they all use the same physical connector: * RJ31X: 8P8C (although usually only 4C are used), Often incorrectly stated as allowing alarm (fire and intrusion) equipment to seize a phone line, the jack is actually used to disconnect the equipment from the phone line while allowing the phone circuit to continue to the site phones. * RJ38X: 8P8C, similar to RJ31X, with continuity circuit * RJ41S: 8P8C keyed, for one data line, universal * RJ45S: 8P2C + keyed, for one data line with programming resistor * RJ48S: 8P8C, for four-wire data line (DDS) * RJ48C: 8P8C, for four-wire data line (DSX-1) * RJ48X: 8P8C with shorting bar, for four-wire data line (DS1) * RJ49C: 8P8C, for ISDN BRI via NT1 * RJ61X: 8P8C, for four telephone lines Unofficial plug names These "RJ" names do not refer to official ACTA RJ types: * "RJ45": 8P8C, informal designation for T568A/T568B, including Ethernet; not the same as the true RJ45/RJ45S More here: http://en.wikipedia.org/wiki/Registered_jack -- So to simplify, it could be for the fire alarm, for any of several different sorts of multi-line telephone hookups, for ISDN (a telco digital circuit), for a DS-1 (aka "T1", a 1.5 MBit telco digital circuit), or, maybe even an Ethernet connector (commonly, but incorrectly, called an "RJ-45"; see above). -- I'll grant that it's *probably* for an Ethernet connection, but I'm not sure I'd bet my Mac on it. Ask the IT folks about it; they'll know what it is, and whether it's even hooked up to anything or not. Many wired networks have been replaced by WiFi and don't even work any more. Isaac

( i really hate going up to the desk! ( for some very good reasons ! ) ) Anyways... Some of the responses here were very accurate...! This is what the help line sent me... Hello, I'm sorry, but those are data lines that are not being used; we use most of them for internal staff connections. Back in the 90s, when this building was built, there were plans to include public Ethernet connections, but there was never enough money to implement the plan (that's why you see Ethernet plugs on the desks, etc.) The public wireless access was an easier and less expensive way to provide this service, so technology has bypassed our earlier plans. Even if you managed to connect to an active line, it would not allow you to access the network without authorization. Hope this answers your question. Spokane Public Library Reference
