One of the cheap things about pay phones is tlial they depend
on i n-band sigtui ling to i nd icate wha I coins you have i use tied .
The operator can tell whether or not you have actually inserted
any money, but now how much . After you insert Lhe in itiaS coin ,
you cm d uplicate the tones for the rest oL the cha rge wi I h a red

TRASHING: AMERICA S SOURCE FOR INFORMA TION

lhe Phone Company will go (0 cMremes on occasion. In

surprise ills heck out of you with their "unpublished tarriffsT
Recently, a situation was brought to my aitention Lhal up till
â ficn 1 had hern Lhially unaware of, least to mention, had any
Cone era about. It involved garbage! The Phone Company will
gn as fa r as 1o prosecute an yOne who rummages through thei r
gmbupe and helps himself to some.
Of course, they have (heir reasons for Ibis, and no doubt
benefit from such action. Ru1â why should they be so picky
abnut garbage? The answer soon became clear tn me: [ho*;:
huge trie la I bins are filled up with mnre than waste, old food,
and refuse. Although ir is Pacific Telephone police to recycle
paper wade products, sometimes employees do overtook this
acred operation when sorting the garbage. Thus top-secret
print! dent ial Phone Com puny records go tn the garbage bins
iusleiid of the paper shredders. Since it is wittlfintly being
updated with "âącompany memorandums' 1 , and supplied with
extensive reference material, the Rhone Company must
CCnbl.i.iHially dii-pose of the outdated materials. Some phone
companies are supplied each year with Ibe complete ââSystem
Practicesâ guide, 'll i is. publication is an over -40 -foot -long
library of reference material about eve tytl ling, to do with
telephones. As the new edition arrives, Ctich year. Ibe old version
of "System Practicesâ 1 must ulso be thrown out.
I very quickly figured oul where SOUkS Local phone phreaks
were getting their uialerial They Crawl inlo the garbage bins

Much of this "Top Secret 1 ?, informal ion is vo secret that most

In another rather humorous incident, a fellow phreak was
rummaging ihtuugh the trash bin when he fumed someone
approaching. He pressed up against lhe side of the bin and
silently waited Tot lhe goodies to enme. You can imagine his
surprise when Ihe garbage from the lunchroom landed on his

Most people find evenings best for checking out their local
tqlco trash piles. The only thing necessary is, a flash light and . in
lhe kim; mentioned above, possibly a raincoat. A word of
warning, though, before you rush out and dive into Ihe Leash
