I understand that the one you can get from the "phone" company is called an RJ31X. My questions are: 1) Where is it installed? (a) In series between the point where the phone line enters the house and all other phones? (b) on the local loop but not at the house? or (c) elsewhere. 2) What alternatives exist? 3) How does it work? 4) Are there any restriction on the distance between the RJ31X and the "Controling Device"? An addition question related to this instalattion, is anyone aware of the need for special permits to operate an alarm auto dialer in Maryland 301-551-xxxx. Please Respond via E-Mail ... If there are enough responses, I'll post a summary. =================================================================== :Bo Newman newman@inco.uu.net uunet!inco!newman : :McDonnell Douglas Electronics Systems Company (MDESC-WDC) : :McLean Virginia : :Voice Mail USA (202) 898-5564 : :ALL STANDARD DISCLAIMERS APPLY : ===================================================================
