NSW AGM – 13 JUNE 2008
Even though it is Black Friday and the AGM, it will still be a
great day. A brief AGM (el Presidente, please note!) will be followed
by the usual lunch, interspersed with tall tales of the past and
the opportunity to meet old friends. As is now usual, it will
be in the Bowlers Club (99 York St Sydney) on 13 June, starting
at Noon. We are again arranging round tables so it is essential
you let us know you are coming so we can ensure there are enough
provided. We are also looking to get a quieter location. Usual
financials, $20 at the door and a cash bar. Bookings please by
6 June to Henry Cranfield (henrycra@aapt.net.au) or (02) 9534-1526
. (David Richardson is moving so cannot assist on this occasion.)
Kurrajong Radio Museum - 13th or 14th
September, 2008 (www.vk2bv.org/museum).
Bernie White hasn’t finalised it yet and is looking for
somewhere we can have lunch. May also attempt a bus to assist
those who might have difficulty driving. More at the AGM and in
the next Newsletter.
END OF YEAR FUNCTION - Mid November
While this will be about mid November, a number of options including
day of the week will be discussed. Your participation in the discussion
at the AGM is needed. Thus there are at least three reasons for
you to be at the AGM, apart from the fact that it is an opportunity
to get together and enjoy one-another’s company!

PRESIDENT’S
MESSAGE[Top]
Well it is now almost 12 months since you elected
me to the position of President of the OTVA and it is once again
time for you to attend the AGM and vote in a team that can enthusiastically
greet the challenges of the next 12 months to further promote the
OTVA and address the requirements of its members.
It has been a year of disappointment mixed with
many highlights. The passing of a dozen or so of our members or
their spouses is of course a disappointment but it is our challenge
to not dwell on their passing but to celebrate their lives through
the memories that they have left behind. To this end Bob Lions has
continued to produce a Newsletter each and every quarter that is
full of interesting stories and informative pictures. The Newsletter
has been the source of stimulation and nostalgia over many years
under Bob’s significant editorial prowess.
The OTVA web site has progressed in leaps and
bounds thanks to the initial work of Joe Collister and over the
past year Chris Bull. Chris has loaded all of the past Newsletters
and developed a means whereby members can search those issued over
the past 10 years looking for specific stories or articles of interest
to members. The information on the web site has been securely partitioned
to maintain the confidentiality of the information retained within
those Newsletters which may be easily misunderstood if viewed by
someone without an understanding of OTC and the characters who made
it great through their efforts and their personalities.
The Executive of the OTVA continues to grapple
with the issues relating to the display and storage of the large
amount of OTC memorabilia. The Telstra Museum at Bankstown is the
repository for most of the archived equipment and materials with
some significant items in the possession of the Power House Museum.
Telstra will be moving the entire contents of the Museum to a new
site in the not too distant future. Our challenge will be to work
with Telstra to ensure that the OTC archives are preserved for the
future.
The Executive has sought input from the OTVA membership
in regards to the method of delivery for future Newsletters through
the survey that was distributed with the last Newsletter. Your responses
are being collated for consideration by the Executive so as to better
improve the balance between the effective delivery of information
to our membership and the management of costs.
The next social outing is being organised for
the Kurrajong Radio Museum and is dependent upon your responses
so check out the details in this Newsletter and let us know whether
you can make it.
Many of our members have complimented the Committee on the change
of venue for our quarterly social functions to the Bowlers’
Club in York Street. The Function Manager works with the Executive
to ensure that we continue to enjoy a balance between good value
for money and the satisfaction of our members.
I thank each and every member of the Executive
for the support that they have given me in the past 2 months and
for the effort and dedication that they continue to deliver to the
task of providing service to our members.
I look forward to seeing you at the AGM on June
13 2008.
Peter Bull (el Presidente!)
SOCIAL NOTES [Top]
See the events page
for a brief report on the NSW Reunion held in March this year.
THE SURVEY [Top]
Accompanying the last Newsletter was a survey
to see how members would like to receive future issues of the Newsletter.
The questions asked are repeated for those who ignored it or forgot
to fill it out.
Survey questions
What do you think??
1. Do you want to continue to receive your newsletter on paper
by post? Yes No
2. Would you be happy to receive it by email? Yes No
3. Would you prefer to download it from the website? Yes No
4. Are you a user of the World Wide web? Yes No
5. If a Web user, how much do you use it? A bit A fair bit
A lot
6. What else would you like to see in the Newsletter? Comment
below.
Please add any comments you might have for
the improvement of the Newsletter. |
If you would still like to respond you should do
so asap. The results, as surveys go, are pretty normal but that
is disappointing. Of about 255 recipients we have received some
69 responses (about 27%). Some of the outcomes are reported below.
Not surprisingly, most of those who responded
by post wanted paper and of those who emailed wanted email. Of those
who wanted email, about half would have either. The message is clear
that members still want the Newsletter. If it were web based, they
would like a notification by email when a new issue was available.
Thus there is plenty of food for the committee but if you haven’t
responded yet would you do so soon, please??
The following comments were gleaned, members would
like to see:
- A member’s list yearly, list of members email addresses
on website and up-to-date photos of members with names.
- Email notification of a new newsletter on the website, membership
invoice by email, membership paid by B-Pay or direct deposit,
- Copies of TRANSIT on website and a copy of ‘THE WAGGA
BOOK’ on website.
- More personal experiences, stories of 50 years ago, CRS memories,
Personal profile activities now and before.
Interim conclusions: (Personal to the Editor as
I have only just done my part and collated the email replies received
as part of putting this Newsletter together.) It would appear that
email distribution should be tried. I would note that previous issues
have ranged up to 3.8MB which is no problem to those with broadband
but could be a problem for those on dialup. It will have an impact
on our postage costs since we will probably lose our bulk postage
rate, but we will have far fewer paper copies to print and post.
The comments offer a number of avenues for investigation
by the committee. However the suggestions for Newsletter items prompt
the immediate response of “Why don’t you write one to
show how you would like to see others contribute?” Writing
this newsletter demands input and as I have said many times before
– “Everyone has a story, don’t be coy, put it
on paper and send it to the Editor”
The results will be sent to the Committee to assist
with future planning. There are also prizes for the best articles
– let your cupidity drive you!
SPUTNIK, THE FIRST ARTIFICIAL
EARTH SATELLITE: By Cyril Vahtrick [Top]
News of Sputnik's launch came on the Saturday
of the October Long Weekend in 1957 and one detail of the announcement
caused some OTC people to prick up their ears - Sputnik would be
transmitting signals at just over 20 MHz (also 40 MHz). It’s
amazing to realize that this was over 50 years ago!
Graham Gosewinckel, then an engineer at OTC's international
receiving station at Bringelly, NSW, immediately began to search
for the signals and was able to pick them up with a sensitive HF
receiver, coupled with suitably chosen rhombic aerials. The satellite's
orbital period (96 minutes) entailed some dexterity in keeping track
of the signals during the relatively short period when the satellite
was over our part of the globe. Graham informed Chief Engineer Bob
Long of his discovery and all other OTC receiving stations were
alerted including Rockbank Vic. and the Coast radio Station in Hobart
which quickly picked up signals and, by comparing signal strengths
and times, a pretty good idea of the satellite's orbital period
was obtained.
Bob was discussing with Cyril Vahtrick the fact
that observations indicated that each succeeding satellite orbit
seemed to have precessed by some 20 degrees or more westward. Then
suddenly it dawned on us - we were of course communicating with
an extraterrestrial object - our world was rotating under the orbit
of this object. A brief calculation showed that the earth was rotating
precisely 24 degrees eastwards per each 96 minute satellite orbit.
This meant that the satellite returned to the same relative position
over us every fifteenth orbit.
On the second day, Hobart Radio telephoned Bob
and reported not only signals from the satellite at the predicted
time but also an actual sighting of the satellite in the evening
sky where it appeared to be the same size as an eighth magnitude
star . Since this was the first reported sighting in the world that
we were aware of, it became of considerable interest to the whole
country. With our by now fairly accurate calculations of the satellite's
orbital path (about a 65 degree angle to the Equator) Bob Long decided
to contact the news media and forecast that the satellite would
be arriving at a precise time in the early evening and that it might
be seen in the south western sky over Sydney at that time.
|
An exploded
view of Sputnik 1 |
This prediction proved to be accurate and a large
number of Sydney people were able to observe the satellite in the
sky. As all this happened over the long weekend, there appeared
to be nobody available in Government departments or the military
to comment on this newsworthy event. As a consequence, it seemed
as if the whole media world descended on OTC for information. In
fact the normal OTC business seemed almost to come to a standstill
for a day or so during the height of interest in Sputnik. We were
besieged by calls and as people reported satellite or UFO sightings
all over the place, Cyril Vahtrick and Ron Knightley rigged up an
orbital indicator on an office globe, with a slide representing
Sputnik. By rotating the globe from a known time reference and moving
the slide on its fixed orbit we had a reasonably good slide rule
which could tell us where Sputnik was at any time.
There was one telephone call where a country newspaper
reporter had heard that a "flaming object" had plummeted
to the ground near a town in western N.S.W. Bob asked him what time
this had happened and, with a quick flick of our makeshift orbital
calculator Bob solemnly announced that, at that time, Sputnik would
have been over Afghanistan!
Graham Gosewinckel made many recordings of the
bleep, bleep, bleep, coded signals transmitted by Sputnik, quite
unintelligible to us or course, but naturally the media wanted recordings
to broadcast to the public. One amusing phone call we received was
from somebody who declared that he could distinctly hear the Sputnik
sounds emanating from his bed springs!
On the serious side, we attempted to use the satellite
to perform some 20MHz ionospheric propagation tests and to have
a general look at our rhombic aerial radiation patterns, but it
was difficult to set up other than qualitative tests.
OTC's involvement in satellites temporarily receded
after Sputnik, with pressures from the real world of HF radio and
the exciting prospect of submarine telephone cables which were now
on the drawing board.
THE MIRACLE ON SECOND
AVENUE: by Bob Lions [Top]
This is a story I have had tucked away for
over thirty years. I heard of the disaster as it was happening from
an AT&T colleague to whom I was talking at the time and he was
watching a news flash on US television. It appeared in “TELEPHONY”
for 14 April 1975.
It is the story of heroic efforts by a customer
oriented telco which impressed me then and again when I re-read
the story recently. In the world of what-if, I wonder at the response
of big T, if a disaster like this were ever to happen in Australia.
I apologise for the quality of the pictures.
These are scans of 30 year old photocopies of a magazine article
so there are many areas in which the quality could be degraded.
The spelling remains American and you are all old enough to understand
the imperial measurements used! I did put in a few metric conversions.

center as fire-fighters aim water hoses at the building’s
windows |
NEW YORK TEL TRANSFORMS DISASTER INTO TRIUMPH
With service to 173,000 phones knocked out by a 16-hour blaze, the
telco and its suppliers produced "the miracle on Second Ave."
ON FEB. 27, 1975, fire devastated a major New York
Telephone Co. switching center, paralyzing phone service in a 300-sq.-block
area of Manhattan's Lower East Side. More than 104,000 lines serving
173,000 phones through 12 exchanges were knocked out in what was
declared the worst fire disaster in telephone history. Just as spectacular
as the fire was the restoration project that followed. It took 21
days of all-out effort by an efficient, coordinated team of workers
and suppliers to restore service in "the miracle on Second
Ave.," as it was described by Lee Oberst, New York Tel's vice
president-New York City region.
The fire broke out in a basement vault of the
12-story building where hundreds of thousands of pairs begin a criss-cross
route through the first few floors. The basement, first and second
floors were hardest hit by the stubborn blaze.
Damage to equipment and cables was incredible
as the fire burned out of control for 15 hours, crippling 31,000
switching mains, damaging 73,000 other mains and five tandems (trunk
exchanges) handling intercity service and trunks into Long Island.
One witness, describing the destruction, said,
"Cables containing hundreds of wire pairs looked like thick
strands of hay, all the plastic insulation had been melted from
them. One outgoing trunk testboard that was made of solid mahogany
vanished except for the wires and metalwork."
As the fire spread through the center, progressing
from one-alarm to six-alarm status, the telco launched emergency
service and restoration programs.
Western Electric, the Bell System's manufacturing
arm, and Bell Telephone Laboratories, its research organization,
were alerted and soon had representatives at the fire scene, ready
to assess the damage and rebuilding job.
At 2 a.m., only two hours after discovery of the
fire, a first-draft restoration scheme was completed. Within 12
hours, the final plan was ready and an hour later it was put into
action.
Mobile units were brought to New York from New Jersey and New England
to supplement New York Tel mobile units in providing service to
hospitals, police and other emergency services. American Telephone
& Telegraph Co.'s Long Lines Department rerouted long distance
calls to maintain intercepts on calls to the affected exchanges.
Supplier reaction is swift.
Western Electric and a number of independent suppliers halted shipments
of equipment and supplies destined for other locations until the
scope of New York Tel's needs was known. Manufacturing facilities
were placed on emergency standby to meet the anticipated demand
for cable, connectors, mainfames, tooling and other critical components.
Even before the blaze was brought under control,
Western Electric engineers pulled out installation drawings for
the 50-year-old building to determine what equipment might be needed.
At Western's northeastern region headquarters in Newark, engineers
and detailers, working in shifts, specified equipment to be ordered
and methods to be used in installation.
Finally, after clearance to enter the building
came from fire officials, dozens of engineers and technicians from
various arms of the Bell System swarmed over the building, assessing
damage and making specific rebuilding plans. Equipment that appeared
to have escaped damage was tested, retested and then tested again.
Teams 'of Western Electric installers ripped out burned equipment
and cleaned up the less severely damaged third through eleventh
floors. Working with them was a chemist brought in to concoct and
prepare a special solution to remove the baked-on grime from switches.

EMERGENCY UNITS provide service in stricken

Second Ave building. |
Meanwhile, some provision had to be made for customers
normally served by the equipment that was burned out. "We had
33,000 customers working from four central offices on the first
and second floors; all panel equipment, completely destroyed,"
reported George Kennelly, New York Tel's assistant vice president-public
relations. "The cable vault and all the equipment in it was
completely destroyed, so there was no chance to restore the four
COs on those floors," he explained.
Connections for those customers were physically relocated to other
telco buildings—one about 3.5 miles away and another about
a mile distant. They will be served from those offices for the next
several months, until ESS (Electronic Switching System – Bell
system equipment approximating AKE) equipment currently being installed
in the fire-damaged building is ready.
By early Saturday morning, March 1, the restoration project was
in full swing. "Our challenge was not only in having to repair
and replace complex equipment," Kennelly told TELEPHONY, "but
we had to accomplish the job with maximum speed and efficiency.
There was no point in replacing cables, connecting millions of wires,
if it was not done with reliability and so that it would be a permanent
job. There just wasn't time to go crawling into that mess to correct
mistakes.”
We were confident that all of our suppliers, both
large and small, would react as we expected them to. They came through
better than we could have hoped. We got the best possible equipment
delivered in the shortest possible time."
Equipment needs during the 21-day restoration
and replacement effort were mind boggling. Components, tools, equipment
arrived literally on an hourly basis, including more than 30,000
miles of cable, enough to drape the perimeter of the earth—and
then some. Cleaning and restoration equipment arrived from all over
the country, parts were delivered by truck, by plane, by helicopter—whatever
mode of transportation seemed expedient at the time.
One of the earliest decisions by Western Electric
was to divert 270 pieces of distributor frame equipment destined
for another Bell company, Pacific Telephone. The mainframe, which
at that point "was just heaps of steel," according to
Kennelly, was held at Western's Hawthorne works in Cicero, Illinois,
and was redesigned and reengineered to New York Tel's specifications.
The 31,000-lb. frame was shipped to Newark, N.J.,
in three chartered airfreighters, arriving within 20 hours after
the fire was snuffed out. From there it was hauled in trucks to
the fire-seared switching center where it was hoisted to the third
floor windows. Through a stroke of luck, the third floor was vacant,
having been cleared before the fire to make way for installation
of ESS equipment.
Installers began assembling the frame on Saturday
evening—by then, teams of 200 installers were working in three
shifts around the clock —and two days later, the new 250-ft.-long
mainframe had been completed. New York Tel's District Equipment
Engineer, Jack Simcox, commented. "I see Western's doing its
customary miracle. I took a look at the mainframe and I couldn't
believe it."
A significant contribution to the success of the job was on-the-spot
improvisation of installation techniques. With the cooperation of
several unions, work went on simultaneously on both sides of the
frame— a practice normally unheard of in Bell System procedures.
In addition, supervisors worked out a method of bringing wires from
one side of the frame to the other in bunches of 100 instead of
singly.
In spite of the all-out effort, New York Tel's
ability to speed up the restoration process was limited to a degree.
In the cable vault, for instance, where 364 cables were repaired
or replaced, each cable's 2400 pairs of wires were spliced one pair
at a time. "You can get only so many splicers into the vault
at one time," Kennelly noted.
By rigging wooden catwalks between two racks of
cables, the splicing was done on two levels, with every possible
position occupied.
Work around the clock
Western Electric manufacturing plants worked around the
clock to meet New York Tel's demand for cable. The Hawthorne Works
shipped 4000 ft (about 1200m) of 2400-pair cable, one of the largest
WE makes, the day after the fire. That weekend it manufactured more
than 35,000 feet (over 10km) of the same type of cable and had it
on its way to New York City by Monday.
Western's San Ramon (California) plant sent 300
channel units within 24 hours of the first call from New York, and
the Kansas City plant received an order for 127 repeater bays. The
bays had to be manufactured to meet the emergency demand, and the
first 42 units were on their way to New York by Tuesday, March 6
(7 days later!). The Baltimore plant shipped cable connectors as
quickly as they came off the production line. That's how it went.
The list of diverted orders and special manufacturing efforts by
Western's plants is endless. At the New York Service Center requests
were filled for every imaginable type of emergency equipment, from
light bulbs to rubber boots, most of which was delivered in less
than 12 hours from the time it was ordered. Still, with nearly 4000
Bell employes working on the restoration on a 24-hour basis, supplies
were exhausted almost as fast as they arrived.

Transportation carriers were part of the team that
performed the restoration miracle. Truck terminals, normally closed
on weekends, remained open to meet New York Tel's needs. Terminal
managers and mechanics as well as trucking crews were called in
to keep supplies moving to the disaster site.
John J. McGlynn, sales engineer for AMP Inc.'s
Telecom Division, was one of the independent suppliers who participated
in the emergency. He told TELEPHONY: "About 36 hours after
the outbreak of the fire, New York Tel told us their initial requirements
for supplies." AMP supplied, initially, 1 million connectors
and 10 standard splicing machines. Expediters at the company's headquarters
in Harrisburg, Pa., alerted distributing depots in Valley Forge
and had specialized equipment flown in to La Guardia Airport within
hours.
"The following day we shipped more, calling
on all of our facilities —Chicago. Dallas, Valley Forge and
Winston-Salem—for the necessary tools and equipment,"
McGlynn noted. "In all, the restoration required more than
10 million connectors and nearly 200 splicing machines. With the
cooperation of all of our divisions and plants, we managed to get
the job done."

Like other suppliers, AMP had engineering and installation
experts on hand in Manhattan to supervise the flow and application
of their products on a 24-hour basis.
John Hougnon, of 3M Co.'s Tel-Comm Department,
St. Paul, Minn., reported, "We had a number of people from
our New York sales branch on hand from Thursday, March 6, through
Friday, March 14, including weekends." The 3M unit supplied
New York Tel with a substantial quantity of connector modules, splice
rigs, crimping units, fault closures and other items.
Another independent supplier involved in the project
was Lorain Products Corp., Lorain, Ohio. Gene Edwards, advertising
manager, told TELEPHONY, "Our service department was put on
24-hour call, and we sent Western Electric a list of names and phone
numbers for our key people in case they were heeded at any time.
"We ran a computer printout of all the equipment
we had in stock and everything we had in production, and this equipment
was given top priority if it could be used in the New York area."
Lorain sent in an 800 amp rectifier and two 100 amp rectifiers that
were mounted on transportable carts. "The advantage of the
100 amp units was that they could be moved around and used where
they were most needed," Edwards explained.
Porta Systems Corp., Syosset, N.Y., was contacted
by New York Tel soon after the fire emergency arose and was asked
to hold all shipments of its products pending a determination of
the telco's needs. Ronald G. Garavello, Porta System's VP-Marketing,
was among those who joined in inspection tours at the fire site
while the embers were still hot.
During the restoration, Fotta Systems supplied
outgoing trunk extender systems, revertive pulse generators, talk/test
line multiples, mainframe work stations, adapter plugs and bridge
lifters.
Frank Gofer, of Audichron Co., Atlanta, reported that his company
was called on for a portable intercept system. The 60-trunk, 12-channel
unit was on order from Mountain Bell, and with that company's permission,
was diverted to New York.
Instant "installation”
The intense restoration program continued over a three-week period,
a condensed version of an 18-month job. New York Tel estimated that
the work consisted of 562 man-years (562 people working for an entire
year).
As the enormous task appeared to be headed toward
completion, an unexpected, but unavoidable, delay put a kink in
the plan to restore service on March 16. On March 13, during the
laborious testing of respliced cables, it was discovered that about
64 of the 364 cables in the building had lost air pressure and moisture-caused
faults had occurred. The damaged cables were replaced at a cost
of five days' time and the cut-over was delayed until March 21,
at 11:59 p.m.
Facts and figures on the big job
Some amazing statistics were chalked up by New York Tel after
the switching center fire:
• 1.2 billion feet of wire placed underground.
• 5 million wires spliced underground.
• 8.6 million feet of cross-connection wire used on
mainframes.
• 570,000 feet of inside wiring cable used.
• 6000 tons of debris removed from the building-.
• 1800 panes of glass replaced.
• 6,156,000 switch contacts individually- cleaned.
• 10 million relays cleaned.
• 1350 quarts of special cleaning fluid used on central
office equipment rehabilitation.
• More than 17 million tests on central office equipment
completed.
|
The New York Tel fire was dramatic for a number
of reasons. In addition to its size and impact on service, the cause
of the fire aroused serious questions. Bell Laboratory technicians
inspected the center and the equipment involved and while the results
have not been made public, sabotage was all but ruled out. New York
fire marshalls hung the blame on a short circuit.
However, as the giant restoration program was
under way, other incidents of possible arson occurred in other telephone
facilities in New York. As, a result, security at major telephone
facilities was stiffened with management teams formed to patrol
the buildings.
When asked about security, New York Tel President
William Ellinghaus replied, "Just try to get into one of our
buildings."
New York Tel was insured up to $75 million, with
a $1 million deductible clause for the Second Ave. switching center.
Costs are expected to come reasonably close to this figure before
the final work is completed. Currently New York Tel estimates costs
of equipment and building repairs at $59 million, but this figure
does not include the costs of installation work or special transportation
used to bring equipment into New York.
Costs, however, were not considered by the telco
in accomplishing its "miracle." Perhaps an even greater
miracle could be any doubts remaining in unbelievers' minds that
the Bell System and the telephone industry in the U.S. is more than
a commercial operation and should be allowed to do its work without
constantly being required to prove that it is doing its best.
(Further thoughts and comments: It is obvious that the building
wasn’t sprinklered, a situation which would not be allowed
today. Also the comment about a 300 block area brings home the follies
of too many eggs in one basket. Anyone who has walked around New
York would testify to the amount of real estate that 300 blocks
covers! Ed.)
WHAT GOES AROUND COMES
AROUND [Top]
At one stage in my life I was responsible for specifying
and installing the rectifier suites for Broadway. A number of innovations
were implemented including going to a modular 800 amp rectifier
unit which could be configured for either negative or positive output
and also (I think) could be configured for either 24V or 48V output.
Thus we bought a number of similar devices and configured and deployed
them as needed.
In another departure from previous practice, they
were to be located on the equipment floor with the equipment. The
batteries, because of their emission of corrosive liquids and inflammable
gases were still in their own rooms, but these were on the same
level. Impressive amounts of copper busbar were used to connect
everything up! This approach provided some interesting questions
since the “new” solid state rectifiers devices, whilst
compact and relatively cheaper than older technologies, were still
very poor in an acoustic sense – they were very noisy! Thus
they would be unacceptable in close proximity to the working environment.
Ultimately retro technology (motor driven variable autotransformer
control) was adopted because of its acoustic quietness.
The whole point of this rambling now comes in
that many years later, as a young engineer working for Telstra,
my daughter, Justine, was involved in the removal of the 24 volt
rectifiers. The circle is complete!

Bob Long
Whilst the passing of Bob Long was reported last
issue we have received a tribute from Cyril Vahtrick.
Robert Rivette Long
As the one probably most associated with Bob Long during his carer
with OTC, I would like to put down a bit of information on Bob’s
considerable impact while he was with us.
Bob was recruited from STC by Trevor Housley in
1953 to strengthen OTC’s engineering capability. OTC’s
then Chief Engineer, A.S. Mc Donald was on extended sick leave and
eventually retired without resuming duty. When this happened, Bob
was promoted to fill the position over the heads of some ex-AWA
engineers who probably felt that they had greater experience than
Bob, so this was not particularly well received in some quarters
at the time.
It quickly became very clear to Trevor and Bob
that the merging of AWA and C&W operations into OTC left many
problems to be solved. The initial OTC management structure, mainly
with ex-AWA executives largely continued a very conservative approach
to development. Although two new HF radio stations were being planned
for NSW, a lot of the planning appeared to be still based on just
extending the technology used in the existing 1920’s vintage
Marconi equipment at the two Beam Wireless stations in Victoria.
At the same time, submarine cable operations were still largely
dependent on decisions coming from C&W headquarters in UK and
even some 19th century equipment was still in use.
With Trevor’s canny intuition and Bob’s
in-depth technical expertise, they proceeded to bring in substantial
changes to forward planning, particularly for the radio stations,
pointing the way to a very rapidly growing future for overseas telecommunications.
There was a specific time target to have the new facilities operating
to meet substantial additional traffic expected when the Olympic
Games were held in Melbourne in 1956.
Bob proceeded to write detailed specifications
for all the receiving equipment at the new Bringelly Station and
all the transmitting equipment at the Doonside transmitting station,
ushering in many new concepts which challenged AWA as the manufacturer
but successfully stood the test of time. Late in 1954, Bob recruited
me from the Civil Aviation Department to undertake the installation
project at the new Doonside transmitting station. This led to a
long and close relationship with Bob extending until he left OTC
in 1967.
Spearheaded by Bob, OTC also started to take a
firm stand on making up our own mind on global technical developments
rather than following the guidelines prompted by the UK Post Office
together with Cable & Wireless.
This stand was reinforced after OTC had followed
UK’s lead with automatic error correction on HF radio by adopting
the TED equipment, developed and built by C&W in UK, instead
of the European Van Duuren System. Having purchased and installed
some TED equipment OTC realized that the TED system was unsuitable
for Telex. With the rapid growth of Telex traffic, OTC had a stand-up
fight with UK on the need to abandon TED. Bob and Trevor quickly
told UK where to get off and OTC took the position from then on
that we made our own technical decisions.
With international time differences, OTC saw the
importance of automatic answer-back with the Telex service. Bob
clashed with our PMG’s Department who saw this as not necessary,
as domestic Telex was at that time mostly in dialogue mode, so people
would soon realize if they were “talking” to the wrong
person. When Bob obtained permission from the Commission to purchase
automatic answer-back equipment for all our Australian Telex customers
and proposed that OTC would install this equipment in overseas telex
customer units, the PMG soon backed off and agreed to install this
essential equipment and automatic answer-back became standard world-wide.
Bob also had a stand-off with the USA carriers
RCA and ITT who operated the domestic TWX telex system in USA. This
equipment was not compatible with the CCITT No.5 teleprinter standard
adopted by the ITU. Bob went over to USA and told them they would
have to change or the rest of the world would not talk to them on
Telex. They did!
I believe that Bob’s drive and determination
prevented Australia’s overseas telex service being put back
several years in its initial phases. In its heyday international
telex actually topped the telephone service in annual paid minutes
before alternative data transmission facilities brought about the
gradual obsolescence of telex.
With the development of repeatered coaxial submarine
cables, against pessimistic forecasts from our finance people, Trevor
and Bob urged the Commissioners to agree to a bold plan for a British
Commonwealth submarine coaxial cable system from UK to Australia
via South Africa and the Indian Ocean, together with Bob’s
plan to augment this with a further cable link across the Pacific
to form a round-the-world Commonwealth system.
Bob’s round-the-world ideas were put to a
Commonwealth conference where the concept was agreed in principle,
but in the end Bob’s proposed Pacific segment became the first
project (Compac) and the Indian Ocean cable project never eventuated
in any form.
The plans to implement Compac foreshadowed a revolution
in the overseas telephone service, supplanting the costly and unreliable
service via HF radio with a high grade medium. In particular, this
raised the question of international subscriber dialling (ISD).
Our PMG initially took the view that such a service would simply
be an extension of their domestic trunk service and thus would not
be an OTC concern.
Bob again took up cudgels with the PMG, pointing
out that, in international telecommunications, it took “two
to tango” and their domestic trunk signalling system was not
only incompatible with the system agreed with our overseas counterparts
but in fact could not operate over the transmission times to be
experienced on very long distance routes.
With strong PMG opposition, Bob secured approval
from the Commission to install a cross bar overseas telephone exchange
at the overseas terminal at Paddington. This service was initially
single operator controlled but again OTC kept up pressure on the
PMG to install calling number identification so that fully automatic
subscriber dialling could take place. After a prolonged battle with
PMG they reluctantly agreed to install the necessary equipment and
the overseas telephone service finally really took off.
With the emergence of the computer age in the 1960’s,
Bob actively encouraged the exposure of OTC’s engineers and
technicians to this new technology, oversighting the introduction
of our first major computer based installation in the form of the
message relay international telegram system. OTC also agreed to
install an experimental computer based telephone exchange employing
the first international CCITT No 6 signalling technology, ushering
in a new era.
For those who had direct dealings with Bob, he
would be remembered as a feisty individual who did not suffer fools
gladly. In particular, he had a profound dislike of the “Divine
right of the PMG‘s Department”. It probably didn’t
do Bob much good with OTC when this extended to the Director General
of the PMG who was also OTC Chairman at the time! This did not stop
Bob from speaking his mind.
I think Bob was very sad to leave OTC because
he had contributed so much to bringing the organization up to world
stature. There is no doubt Bob left a substantial mark on us.
In his retirement, Bob eventually moved into a
retirement village in Belmont where he looked after his ailing wife
Gwyn until she passed away a couple of years ago. By this time,
Bob had had a stroke and had lost most of his hearing. He commuted
into Belmont on his “gopher” for shopping and walked
around the retirement village premises with a frame. Nevertheless,
his sons tell me that he was still trying to “run the place”
on efficient lines – Bob was like that!
Austin Ellis
Austin Ellis: Passed away on 22nd April 2008 in
the Frankston Hospital Victoria from complications of a stroke aged
about 86/87.
Austin Ellis left AWA in 1942 after attaining his
radio certificate and went sea during the war and returned to the
communications field elsewhere after the war. He is survived by
his wife Peg and Family. He had a passion for flying aeroplanes
which he was still doing in his early 80's and loved fishing and
still made his own radio and computer equipment and had a profound
knowledge of all things he liked to do including music. (Robert

MY LAST “LAST WORD”
[Top]
As some of you will be aware, I have decided to
retire as Editor of the Newsletter so that I can get some time to
smell the roses. This is only one of the tasks I am seeking to shed
and I suspect that it will be some time before I do actually have
the leisure to find out that most modern roses have little perfume
– they are bred for their colours and shapes!
However, I am pleased to advise that Martin Ratia
has accepted the position so I am happy that the position now passes
from amateur to professional hands. Please continue to create and
send your contributions.
