CLASS is short for (C)ustom (L)ocal (A)rea (S)ignalling (S)ervice. CLASS is a new state of the art communications advancement that can add security and convenience to your daily life (says Bell). Features of CLASS Calling Service are: * Automatically redial the last number that called you. * Automatically redial the last number you dialed. * Automatically display the phone number of an incoming call-with the help of an additional piece of equipment. * Automatically forward all your calls to another location. * Automatically forward calls from up to three specific telephone numbers to another location. * Automatically give your phone a distinctive ring for calls from up to three telephone numbers you select. * Automatically give your Call- Waiting tone a distinctive sound for calls from up to three phone numbers you select. * Automatically reject threatening or unwanted calls from up to three telephone numbers. * Automatically trace the telephone number of the last call you received, and have it forwarded to the telephone company. My area has been chosen to participate in an important one year trial of CLASS Calling Service. My home was one of the 65,000 area households that are connected to this special network. The Harrisburg, Pennsylvania, area is the first in the entire country to introduce CLASS Calling Service. Generally, CLASS Calling Service will work on telephone service other than party lines, trunks, and fortress phones. CLASS features may only be used if both the called and calling telephone numbers involved are located within the selected areas. To help people in my area become familiar with the new CLASS Calling Service, Bell of Pennsylvania has prepared a separate, recorded message describing each of the services, and demonstrating what its special tone(s) sounds like. Call the listed numbers to hear useful announcements. Automatic Recall 717/221-0066 Automatic Call Return 221-0069 Distinct Ring-Call Wait. 221-0061 Usage Call Forwarding 221-0072 Selective Call Forwarding 221-0063 Selective Call Rejection 221-0060 Customer Originated Trace 221-0057 Delivery Blocking (Caller ID)221-0067 CLASS features cannot be used if a pay phone is making the calls. The Caller ID lets you view the telephone number of an incoming call before you answer it, with the help of a separately provided place of equipment. The 7-digit number attempting to reach you will be delivered to your display equipnent, as your telephone begins to ring. If the call is from within a multi-line or four party/muli-party service, only the "main" telephone number will be displayed. If the call is from a private telephone number-or if a listed caller has chosen to prevent his or her number from being displayed the call will be displayed as such. If the call is from outside the CLASS Calling Service trial area, or from a "public" pay phone, the call will be identified as such. All CLASS commands on a touch tone phone are preceded by hitting the "*", then the numbers on the phone to activate the features. During the first few weeks of our trial with CLASS calling there were alot of fuck ups made by bell. Some commands didn't work properly. Using one command activated another command that wasn't programmed to be functioning. Also for awhile the Caller ID display units service was discontinued. They couldn't get the damn things to work right, they displayed numbers when you didn't want them to. And they were billing people when people couldn't shut them off. So for now at least Bell has dropped the Caller ID unit for the meantime. Also, if you think Bell is offering these features for free think again. Here is a billing chart they sent out. feature activation storage --------------------------------------- Automatic Recall .15 - Automatic Call Return .15 - Dist.Ring/Call Wait. .15 - Usage Call Forwarding .20 .20 Select.Call Forwarding .05 .05 Customer Orig. Trace 3.00 - Caller ID .05 3.00 --------------------------------------- When it first came to my area we had all the features for free for two weeks. Also to order the Caller ID unit there is an 800 number to call and order it. The unit is free and you only have to pay the shipping and handling charges which were only $4.90. After about one month of screwed up CLASS service Bell finally got everything working without those fuckups I mentioned before. Alot of the local BBS systems like to block people out from calling there board with the call rejection feature. What happens when you attempt to dial a number of a person who has your number blocked out is you get a tape recording. It says "The party you are trying to reach is not accepting your calls." I myself tend to think that there is some weakness in this service that us phone phreaks can do to raise havoc with ole Ma Bell. Rumor is that there are alot more than the nine publicized commands told to the public by Bell. Now that we have this service I will be conducting various experiments to try and find flaws in the system and all. I will be trying to find new commands that the public wasn't told and send some tones during the time that CLASS sends it tones. Maybe I can find something out. This will be all trial and error experimentation. Many experiments will have to be conducted. If anyone has any thoughts or suggestions about CLASS calling leave a message to CHAOTIC DEMON. On the Motor City Underground and a few other bbs systems. Or look me up yourself, I call alot of systems. Look for Part II of this file revealing results of my experimentation with the CLASS Calling system. New technologies like this open up doors for new ways to break the law and who knows what else.
