    CLASS Calling Service is a new technological invention Bell has added to
my area. 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.
