DSC pc1550 phone wiring and modem problems

Hi guys,

Recently moved to a home that had a non functioning dsc pc1550 ver 4.0 alarm system. I now got it working and I'm interested in hooking my pc to the system. I have the DLS-2002 software installed and modem ready to go. As of right now, I'm not subscribed to any monitoring company. Now, my first question would be, can I connect to the alarm's control panel with my modem being that both are sharing the same telephone line? Would I just get a busy signal from my modem cause I'm trying to call myself or is this a wiring problem. I appologize if the question seems kind of stupid but I am an extreme newbie at this.
In this case, would a direct pc link be the only solution? If it is, any ideas?

Second Issue: Phone Wiring.
In my alarm panel I see the R-1(gray), T1(brown), RNG (red), Tip(green) were all connected, I traced the wiring to the what seems to be the main telephone distribution box located in my kitchen. To my surprise, all the wires from the alarm were disconnected. This main phone box also has a phone plug in which only has a the red and green wires connected to it. I can't seem to find the other 2 wires in this box. I connected the red and green to the alarm panel and even got the alarm to call my cell phone, but R-1 and
T-1 are still disconnected. Do these need to be connected in order to access the control panel via my pc?
Any help would be humbly appreciated. Thanks.

First, I'll give you my stock answer regarding the download software: It was designed for installers to program multiple systems; it really was not designed to use for end-user system management.

You cannot connect to the system without either dialing in from another telephone line, or using the direct connect hardware.

It sounds like your system may have been connected to the telco wiring without a RJ-31x jack (not "kosher" but was often done by DIY and fly-by-night installers in the past). You may wish to follow the link on alarm telco connections in the FAQ for this forum. R and T should be connected to the incoming telephone line. R1 and T1 are to return the phone line to all of the house phones downstream of the line seizure mechanism)
