Hi everyone. I am a newbie when it comes to setting up phones and cables, so I will appreciate your input on what I should do to setup 2 landlines at my house with CAT5e cables to support 2-line phones in multiple rooms. We have Cat5e running everywhere throughout the office with multiple cables to every room. They were all punched down into RJ45 keystone jacks in the rooms on one end; and they were terminated at a central location as RJ45 plugs (with RJ45 crimp connector). Recently I have Verizon come to install FIOS and 2 landlines phones. The installer put a box in the central location and ran two Cat5e cables from the box. One of these Cat5e was for FIOS and got plugged into the modem/router. That part is easy for me to understand. However, the second Cat5e cable from the box had 2 pairs punched down on a RJ45 keystone jack. The installer told me that was for the two landlines. Now I am a bit confused about what to do to get dial tones. I have put our cabling into the following diagram. Hopefully that will help clarify things. My questions for everyone are: (1) What do you think about my plan about modifying RJ11 cables into having one end as RJ45 plug? (2) What should I do to connect all the cables to get dial tones for all locations? I am thinking about using a switch, but I really have no idea what to do at this point. Thank you so much for your patience reading through my lengthy explanations and for your help.

[LIST] [*]I have POTS (Plain Old Telephone Service) home landline telephone and DSL internet with AT&T Bellsouth. (I do not have any U-verse services. U-verse is not available in my area yet.) [*] For several weeks, there was some static on my phone line and the sound was unpleasant, but the phone was still usable. Then a few days ago, I lost home phone service altogether. I have no dial tone on any phone. My DSL internet service continues to work. [*] For a few random times, the home phone service could be restored by calling my home number from my cell phone. It was a temporary fix but I would have a dial tone again for a couple hours. That process only worked a few times and is no longer working. [*] One of my cordless phones shows "Line in Use" on its display. [*] I have a corded telephone (good old cheapie $9.99 plug-in handset/test phone) that I can use to test jacks. [*] I tested the line at the NID box outside my home using the cheapie plug-in handset. I do have a clear dial tone at the NID and can make outgoing calls from the NID. So if I understand everything I have read, that indicates the problem is either with the inside wiring, inside telephone equipment, inside DSL filters, or somewhere else inside the house. [*] After the home phone service was lost, I got an error message from my Netgear modem that it had detected problems with my DSL service. See attached print screen. I ran "Check Connection" tests on the modem and received "Fail" for IP and DNS tests. Looking at the "Details" of the IP error, the failure was in the "Continuity check to 6rd BR". The "Details" of the DNS failure show a failed query and ping. [*] I was hoping it would be a bad DSL filter - even the modem's warning indicated that. I removed every phone and every DSL filter from every phone jack in the house. I turned the computer and modem off and unplugged the modem from the wall jack. But using the cheapie phone, without a DSL filter, I still cannot get a dial tone in any jack. So I do not think the problem is with my phone equipment, DSL filters or modem. If I cannot get a dial tone using a known working phone plugged direclty into any jack, that eliminates failure of the equipment, DSL filters, and modem, right? [*] What else can I test? What else can I do to troubleshoot and fix this myself? [*] Is it possible that the problem is in the wiring inside the NID box itself? In my reading on the internet, I am led to believe the problem could be there. If so, whose responsibility is it to pay for repair of wires inside the NID box: AT&T or the homeowner? [*] Any other ideas what I can do to fix this before calling an electrician? I do not have the Inside Wiring Maintenance (insurance) coverage/plan. [*] For several days, the phones have produced no sound at all (completely "dead" and silent). But after fussing with the jacks, filters, etc. while writing this post, I got a loud, constant "full" static sound. Hmm? Only the computer modem and one phone were plugged in (different jacks). Now it has gone away and the phones have no sound at all again. [/LIST] Thank you very much for reading this and any help you can provide. It is greatly appreciated! (Attached photos are below.)
