What is free space? Well, cm all RSTEjj H systems, Lherc if. a 
portion of the lI is k assigned to Tree spaoc\ which ^ basically 
space foot for the saving of files. When >'0U issue u save, or open 
command, RSTS/E simply grabs however many blocks arc 
needed from this spoor, and stones your £ik Ihere. 'Then this 
space is marked as he ing 'unavai table’. Wise is you delete, on V i 1 1 
a file the ts.fi a [opposite happens, RSTS/E moves a few 
pointers, which mark this space as ‘available', (or free} space, 
leavi ng the enti i c fl le 99% of 1 he t irne totally in m ei ! r H+ijij is an

where: file. ext = any^albd filename you want the free space to he 
placed in XXX XX%. - any intent between ! and 12769 
inclusive, Idling how many blocks of free space you wish 
transferred into 'file. eat’. 

Forexampbe, if 1 wanted Lo read 500 blocks of free space into 
a tile called Tree.spc’’ 9 would write my program as foflowl: 

I ft open “free .spc” ns (1 le 1% 

3> put if I %. record 500%

40 end 

Now in my dircel o ry would he t he fi u; ’'frcc.Spe " |to ]d ing !i I.H.i

THE HISTORY OF ESS 


bj La Lulhfli 

OF all the new wonders of telephone technology — 

satellites, yltfii’mcnlem Traffic Men/ ice Positions (TOES) for 
operators, lhe picturcphonc, and so on she one Lhnl gave Hell 
I jibs lhe must trouble, and UTCXpCCLed Ly became the greatest 
development effort i n Bell SyrtemY history, WAS | he perfection 
of 3(1 electronic switching system, or ESS- ESb should be welt 
known to many a technical enlhusiast. It is known as Ihe big 
brother of (lie phone system, capable of controlling almost all 
aspects Of any phone call and keeping track of calling patterns. 
How FSS works and what Lt is capable of has been covered 
previously m 2r W (February, J9&4) and will ibc covered in 
future issues. 

lL may be recalled that such a system was the specific end in 
view’when the project that had culminated in Ibe invention of 
Elte Irnosistor had been launched track in the mil's. After 
successful accomplishment of that planned miracle in 31*47-411, 
further delays were brought about by financial stringency and 
the need for further development of the transistor Itself, In the 
Gariy i95U's. a Labs team began serious work on electronic, 
switching. As early as [£S$ r Western Electric became involved 
when five engineers frusn the Hawthorne works were assigned 
to collabnra e with the Labs on the project. The president of 
AT&T in I 9; wrote confidently, “A i Bell Labs, develop] nem 
of 1 he new electronic swilehing system ;s going full Speed ahead . 
We urc su re ti ns will lead to many improvements in service ami 
also to greater efficiency, fhc first service trial will start in 
Morris, Illinois in 1959,": hurtly thereafter, Kapptdsaid that 
the cost of the whole project would prnhfihly be $45 mtlhon. 

But it grad u a lly became apparent that 1 he development of a 
commercially usable electronic switching system— in effect, li 
computerized telephone C.stchange — presented va&llv greater 
1 ethnical problems thitn bad been antieipitted, and that, 
accordingly, Bdl Labs had vastly underesl mated both the time 
and the investment needed i&duthejob. S he year I9;s9 passed 
without tbe promised first trial at Morris, Illinois; it was finally 
madc.in November 10 W), and quickly showed how much more 
work remained to be done. As lime dragged on and costs 
mounted, there was concern at AT&T and something 
approaching panic ul Well Labs. Bin the project had tn go 
forward; by this time Lhe investment was loo great to be 

equal access may not be 

fry Tlie Shadow 

Now that AT&T is being divested of its Local telephone 
companies, phone customers across 11 m nation have lo choose 
Ibei: Long distance carrier as “equal access” is phased in 
.Advert isingcampu igns emphasiic such aspects as low biles and 
Operator iissirtunoe, but almost no One iiienLiuns. a factor chat 
will affect modem users who useaulu dialers for longdistance 
calls. Not all of the alternate Jong distance carriers pruvide 
called parly answering supervision on all calls, Called parly 
answering supervision basically has the tdepluuie company 
slarl billing univ when the called party a nswera lhe telephone, 

I lowever, ma ny of clie a lie mate Long distance companies sLil I 
operate wilh the “fixed timeout” basis for charging. That is| if a 
Call is he Id for a fixed lengi h of time f usually 30 seconds), Hie 
charging starts, u hrtJwr or not tfa 1 mtt h-t j ,s (WJueertW. 

1'his could cause modem owners large bills if they use 
aptodiii lers to make Song d istairce calls. M odenu are usually sel 
uji ip wait up to one minute when attempting to make a call, 
and thus have to timeout through busy signals. Song -call setup 
sequences, extender waits, and simitar problems. Ibis could 
result in many billed but unanswered calls. 


sacrificed, and in any ease, forward projections Ol" increased 
demand for telephone service indicated that wilhin a few years a 
time would come when, without the quantum leap in speed and 
flexibility that electronic switching would provide, the national 
itttwOrk would be unable 10 meet the demand. En November 
!**63, au all-cleelronic switching system WITH into use at the 
Brown Engineering Company aL Cocoa Beach, Florida, But 
this was a small insinuation, essentially another test 
installation, serving only a single company, K uppers cone on 
the subject in the 1964 annual report was, for him, an almost 
apologetic: ’‘Electronic switching equipment must be 
manufactured in volume to unprecedented slundardsof 
reliability.... To turn out She equipment economically and with, 
good speed , mass production method s must be developed; hut, 
at the same time, there can bo no loss of precision..,," Another 
year and millions of dolbira later, on May 30, 1965, the ilrst 
commercial electric. central office was put Into service At 
Succasunna, New Jersey, 

Liven at SuccA-Suuna, only 2(10 of the town^4 JOO subscribe rs 
initially had tlse benefit of electronic s witching Y added speed 
and additional services, such ax provision for three party 
cnnvci'SiUionv and automatic transfer of incoming calls. But 
afler that. ESS was, on Its way. In January I9titi, the second 
commercial installation. Ihis one .serving 2, 900 telephones, 
went Into service in Chase, Maryland. By Che end of 1967 there 
were additional PSB office! in California, Connecticut, 
Minnesota, Georgia, New York, Florida, and Pennsylvania; by 
the end of Ef*70 there wen; 130 offices serving 1,8 million 
cnstonSers; and by 1974 there were 475 offices serving 5.6 
million customers, 

Lhe diffcicnec between conventional switching and 
electronic switching is Ibc difference between "hard ware 1 * and 
"software”; in the former case, ma intenance is done on the spot, 
with screwdriver and pliers, while in the case of electronic 
switch mg, i [ can he done remotely, by computer, from a central 
point, making it possible to have only one or two technicians on 
duty at a time at each switching center. 

Tlse development program, when the final figures were added 
Up, with tound to liavc required a staggering four thousand 
man-years nf work ai Bell Labs and to Ira ve cos-1 not £45 million 
but miltiorll 

"equal” to modems 

party answering supervision On all calls to all points presently, 
it's almost impossible lo get information on how a long 
d ista nee company charges its calk as I hey don ’I want tn reveal 
how Lheir billing Is handM. 

The alternate ca rriers get called pa ny supervision when the 
tfrtimatiim location gees equal access. I lowever, there h&i been 
no quick action nn else part of the alternate Long distance 
companies to make USe of the supervision data as they would 
have to get equipment for passing cbe information back to the 
biding computer at Lhe originating point. Thus, called party 
answering supervision often ends up being ignored by these 
earners even when Ava ilabk. 

The luwcr rates of alternate long distance compan ics mutt be 
weighed against the timeout problem as it alfecis autodialing 
modems, One way to circumvent this is merely to set your 
modem lo a shorter waiting-for-corincct tunc, but this may npl 
provide enough time for lhe call tu go through. You could also 
claim cccd it for each And every one of the calls vou get billed for 
that doesn't actually connect but that can be vercJ 
tulle "consuming. " 

Keep in mind also that alternate phone companies with 
primilive billing methods will often not detect short JlQ-sceond 
phone caEls..,. 


Some of the otticr Cfi rricra provide this on calls 10 lome cities, 
and ochera don't support it at all, Only AT&T provides called

‘obscene, lewd, lascivious, liitby or indecent" material via 
telephone or cabk television. The bill, introduced by Helms 
would make it a federal crime even for 11 married COup le to ha ve 
a sexual ly explicit conversa tion over 1 he telephone. It wou Id be 
punishable with a fine of and up to two years in jail.

Worried Pbrfiflk 

Dear Worried: 

Rkte boxes are indeed a dwindling re sour ee. But there If no 
need Ut throw them out yet. They aren T t going io he totally 
useless for quite some /«. 

Bastettlfy, AT&T is converting gradually to CCIS trunk*. 
These don 't allow hoxhig. 

In- hand signaling is the only kind of trunk signaling that, 
supports boxing. It is try far the most prevalent at the moment. 
Ikssicttlly, in-band uses a 2600 hertz tone to indicate that a trunk 
is idle, flnrf chits eon accept routing Instruct itons from an 
" outsider 

To Box a call, the criminal blasts 2600 down the Ime after 
making a Sony distance calk 77a: Unit thinks it (v idle and wails 
for routing instructions, Now the criminal puts a KFtone and a 
ST tone around the number that he's trying to get through to, 

1 he.se comprise the routing instructions. Thus, the line thinks 
it If idle, then U receives the routing instructions, and routes the 
nail lo wherever the person sent it. A'cav, Mi eentrai off tea (CO'}, 
which does all billing still thirties he is making she rail so 
wherever , so it keeps on bill mg him at thas rate. If it happen i- So 
think he was making a soli- free call. it won'! bill him at all! 

Another form oj signaling is out of band. Tins uses control 
tones out of the normal hand of telephone transmission 
{approximately S00 hertz to .1000 hertz). The idle tone is 2201), 
others shifted upward ur wait So whyeoukln lr you lust make a 
new box Y Don 't forget, it jt out of hand. These tones aren V nr 
normal transmission.- so the local CO and customer interface 
loop Just don V bother lo transmit them. You can blast all the 
,f iW you want— it won t go through the CO to the trunk. But 
this is not the "death of boxing "as. u has several disadvantages 
to the telco too numerous to mention. 

77k real death of boxing lies in Common Channel Interoffice 
Signaling ( CC 1%'j. This is it direct connect data line going from

The Early Phreak Days 


by .lint Wood 

When [ decided to gen mar? icd batJt in 3962, 1 traded my DJ 
and broadcasting: odd jobs for one al the phone company; 
employment which, iat that time, wan ultimately secure though 
my take-home pay was about S30tJ a month, 

Ass i fined to lire Pa bn Al to, Ci'Oi fumiu central office as a Toll 
Tnansmiaionnmn, my duties included maintenance of toll 
traffic circuits and related short-haul N and ON carder 
equipment. C’inenit testing was initiated al a black txikeiile T ype 
37B Toll T&lbOJirtl. A fieJd of several hundred tacks gave 
acGiss to as many inter-office trunks, many to the San Jose 4 A 
and Oakland 4\] 4-wire switching centers. 

Though it was strictly forbidden, one could easily and safety 
"dcadlread” toll calls for one's self, family or friends from the 
ics1I.ilX! i'd . Around Chrislmastime our office could easily have 
been contused with the Operator room, OH the floe i beiow. 

E'hc 1 7 B test hoard had a 0*9, DTfvlF keypad arranged in two 
rows of S bu It ‘iis wired to the central crltYcc "mult ifrcq" supply. 
A rack of va num tube L/C oacilta-ors comprised the MF 
supply and wa buried somewhere in the bowels of ll>C build irijy 
Long days with too much {mostly union) staff and not 
enough to do precipitated a iOt of screwing around on the job. 
Some of 1 he guys would j usl dayd ream out the window's, others 
would hassle and torment the Opaalon* downstairs. One 
favorite 1 i i eh vans to sneak into Lhe access space behind the hank 
of 3C switch beards and push the cords slowly up toward the 
Operators. I lie screams and comns Olio it caused by a tip, ring.

and sleeve “snake” was worth the risk of getting chewed out by 
1 he old battleaxewho ran the place. Myself'., 1 just played with 
the Bell System; never with any Intent to defraud, merely LO 
increase my understand ing of how the whole thing worked . 

3 1 Was during a singularly dull day that 3 hit on the idea of 
“deadheading" calls throufih one nf the local subscriber loop 
lacks which rang inlo the testbeard. Sure enough, f could 
rotary -dial through the step office to Sacramento (the sliortcst 
hop on L earner with inhand signalling),, "dump” Ibe CfiJ! in 
Sacramento with a blast of 2600 from the l$c oscillator 
mounted overhead, then mullifreq out of Sacramento 
anywhere l wanted to go. Wow! I could hardly wait to 
demonstrate this potential source of Lost revenues to my fin?t- 
Line supervisor. Both he and his boss were mildly impressed , but 
assigned minima! importance to the event since, m their words,

office was in tire alarm circuit of the ON carrier system, Tire

to work in a bridged -T oscillator configuration. A half-dozen of 
these, some Olson Radio pushbuttons, and a handful of 
resLsIora and Cii ps made a dandy M F supply. 

The next demonstration was from tS^ Chief's Own desk and 
d id tliially raise some concern. L was asked to "donate” the bOK 
and told to keep my findings strictly I o myself T have done so 
for more than 2fl yeans itow,
