2 edits | Re: [Split] Fax, Modem or Alarm System, LPV Proble I'm still working on my full review of the service but can confirm at least that the modem issue is real. Under LPV, my DirecTiVo (TiVo for DirecTV satellite service) cannot use its analog modem to call in. It's well known though that a DirecTiVo doesn't really need to call in except in the case of a software update (and since DirecTV is ending their relationship with TiVo, not much chance of that). So this doesn't worry me too much. I haven't had a chance to do an alarm system test yet to find out if that's affected (the alarm and TiVo are the only analog phone devices I have other than voice phones, which of course work)
Update: Did an alarm test with my alarm monitoring company (ADT) and the alarm did call in properly. So at least recent ADT alarm systems work fine with LPV. I have an ADT touchscreen system that was installed in late 2004. | |

| Re: [Split] Fax, Modem or Alarm System, LPV Proble Thanks for the feedback. I'll have to try again with ADT when I have time this week. Did you do anything special to test? Also, what's your filtering setup?
I still can't get the analog modem or fax machine to work. The fax is far more critical. | |

1 edit | Re: [Split] Fax, Modem or Alarm System, LPV Proble Is it a Fax communications breakdown or a 10 digit dialing issue?
Have you tried lower the fax rate to 14.4k or 9600 if it is a communications error?
Have you tried placing a DSL filter on the FAX device but placing it on backwards so the filter is at the machine and the line cord goes into it from the wall??

1 edit | Re: [Split] Fax, Modem or Alarm System, LPV Proble It's definitely a fax communications breakdown, as it dials the number, gets to "connecting" and then just hangs. You can even hear the first bit of the fax tone.
I've tried turning off error correction and V.34, which are the only fax settings I have access too (this is a HP Laser multi-function machine).
FYI - I have a DSL/Voice splitter at the NID, so none of the phones, fax machine or alarm system inside the house should require additional filters (or at least they didn't when I had regular ADSL service). At any rate, I tried adding a filter in both directions at the fax machine, it didn't change anything. | |

I still can't get the analog modem or fax machine to work. The fax is far more critical. Unfortunately it turns out I have the alarm problem as well (the alarm managed to work once, but not consistently--eventually the ADT touchscreen complained about phone line problems). I don't intend to return to a standard analog voice line if I can help it, so I'm looking at options for dealing with the alarm. According to ADT, they offer an option for most of their alarm systems which allows the system to communicate via cell phone. Hardware cost is $199 (before $75 rebate), plus an extra $5/month for monitoring. In the long haul, I can make up that cost by staying with VoIP, and this will probably be a problem no matter which VoIP solution I go with ultimately. jcricket, if you can get the fax to work (or perhaps use one of the online fax options like eFax) this might be a way to handle the alarm problem. | |

| Re: [Split] Fax, Modem or Alarm System, LPV Proble Thanks tquan - Please do find out. Earthlink tech support's only suggestion was dial "*99" before using the fax. I tried that, and the result is nothing (literally). The fax dials the number and then no ringing, no connecting on the other side.
I'm definitely interested to hear what people at Covad have to say. | |

2 edits | Re: [Split] Fax, Modem or Alarm System, LPV Proble I've replied to tquan's question in the Covad Forum, and I guess I'll reply here.
Many of us in the Covad Forum do not have access the LPV testing app. Only a small group within Covad have access and that's because LPV is still in it's testing phase. Sorry 
I've installed at least 10 LPV circuits in Atlanta (for the ELNK execs) and they have all gone smooth. I can only remember one circuit that was installed in the ELNK's Corp building being used test alarm dial out circuits. Not sure how that went. | |

1 edit | Re: [Split] Fax, Modem or Alarm System, LPV Proble So did you test fax functionality on those circuits? The basic functionality (voice + dsl) work fine for me.
Or, better yet, any way for us to get in touch with people inside of Covad (through Earthlink) who do have access to the right knowledge/tools?
Edited to add: My issues are all on the voice side right now, in order of importance:
1) Analog fax machines cannot make outgoing fax calls successfully.
2) ADT Alarm systems do not connect. My alarm company reports receiving "no signals" when I perform a test.
3) Analog modems cannot successfully dial out and connect to remote modems.
4) Voicemail indicator appears not to work. It's possible that my phone relies on the "stutter tone" and not "FSK" for VM indicators. Supposedly LPV offers VM notification via FSK. I have not verified this yet.
5) Caller ID timestamp is off (no matter what you set as your timezone in Earthlink's web portal). The timestamp is correct on the voicemail messages
The DSL and regular phone service work, including caller ID and voicemail functionality. | |
