First off I'm a network guy, not a phone guy. I inherited a network and was recently asked the question if we can get rid of a certain phone line that was hardly ever in use..only has like one call a month on it if even that. I trailed that line down and found out it went to a modem rack. The device is shown on the link below:
The problem is, I have no idea what it is or what it does. I see it has four phone lines going into it, (this included the particular phone line I was trailing.) So I have no idea if I should get rid of it....any idea what it could be used for?
I have a picture of it below too. It has some type of switch connected to it. The only two lines plugged into the switch are coming from the back of the Modem. The Modem also has a Ethernet wire plugged into our lan(and of course the 4 phone lines I was speaking about earlier).
