The DSC unit provides a dialtone which will prevent the second channel fr om going into line fault trouble in either case. Both channels will transmi t full system status as long as you've programmed them to report in CID. On a side note, there's been some problems with the GSM-3060's dropping off t he network (so I've heard). We've got about 200 of them in the field and, s o far, we've had no issues.

Sommmmme Daaaaay ...... DSC may be able to finally get it right.
I had that problem years ago with one of their cellular devices. That's whe n they first came up with the "brilliant" idea to do away with redundant re porting. When I complained about the fact that the telephone line could wor k for 10 years before the radio ever got to transmit .... they said OH .. b ut it sends in the supervisory signal so you know it's going to report. Sur e nuf .... they had a recall a couple of months later when they discovered that the radios were sending in supervisory signals even when they couldn't transmit an alarm signal.
Then most recently after the Sandy storm I had one DSC GSM radio left. Afte r customer got power back I went back to get the system back on line and th e radio wouldn't work. I called DSC and was told .... OH YEAH, that radio h as a problem. When you loose power and the battery goes to zero .... the un it is shot. AGGGGGGHHHHHHHHHHHHHH! I guess it was a little too inconvenie nt to issue a notice to the trade.
Needless to say..... No more DSC in my future.
Besides, their equipment is made out of tinfoil, dried mud and compressed c ardboard.
