A SPECIAL ISSUE LIBERATION OF $--

DEDICATED TO THE COMMUNICATIONS """1-llt

UNDERCURRENTS is designed and edited b y Sally and Godfrey Boyle. Pat Coyne edited the News, and Tony Durham edited the Reviews and took pictures. Peter Harper was editor-withoutportfolio. Typesetting was

by Jenny piinings, pictures were processed by Julian Stapleton on Time Out's camera, and Joy Watt handled the subscriptions, distribution and promotion before dropping out to make her contribution t o the population explosion (a girl}.

Chris Hutton-Squire grappled manfully with the balance sheets and cash flow figures, and the people at Metro grappled personfully with the rising tide of mail. Martin Ince did astronomical work, Barbara Kern drew the nice diagrams, Gavin Browning turned us on t o SF, and Charlie Clutterbuck fearlessly sought out pollution.

Support, both moral and practical, came from m quarters: David Gardiner, Pat Rivers, Sooty, Geoff Wat,ts,Lance and Penny Sucharov, Ian Hogan, Steve Boulter, John Wood, Cliff Harper, Lyn Gambles, and Robin Hall a t e a few among the dozens who deserveand have our grateful thanks.

CRASH STOP PRESS Irish TV ran a documentary on the Viscount crash on June 18, and Hibernialdid a similar story on June 21.

Latest reports suggest that new-found wing is from a U K pilotless drone. It's at times like these you regret that Undercurrents takes two weeks to print.

TABITHA'S FIRELE ER is a trendy version of the old-fashioned hay-box, developed by food-technologist Tabith: Beazeley, NDD. The idea is that almost any dish which needs fairly lengthy cooking-like casseroles, curries and Christmas puddings-can be boiled gently for 5 t o 25 minutes, quickly tucked into the cooker, and left, fully insulated to cook for a few hours, or overni&t, so that 'slow cooking takes place without the further use of fuel", and without burning the food.

All you need t o provide is one double-handled metal pan with a lid, although the maximum size of hay allowed changes from 12 inches on one page of the instructions t o 8% inches on another.

Tabitha's main argument against hay-boxes is their bulk, in today's cramped society, and the apparent lack of hay to make them with. She has come up with the idea of a cosy jacke made of some modern, nameless insulator, which wraps round your.cooking pot. There are pillows for the base and a folding box of the same material tucks up around it.

'The well-known method of opening letters by holding them over a steaming kettle is effective but messy, and is not normally used by professionals. Indeed in many cases it is not necessary to open ah envelope in order to scrutinise the contents. Do-it-yourself enthusiasts can verify this by holding an unopened letter close to a strong light; in this way most typewritten letters can be read quite easily.

The Security Service have specia apparatus for examining letters by this method, the device they use b rather like the viewing screen foun in X-ray departments of hospitals. this method proves unsatisfactory, the contents of an envelope can be extracted through one of the holes at the top of the gummed flaps.

Cruder methods are simply to or destroy the letter, to use an 'Opened in Error' label, to write 'Misdirected' on it or 'Not known a t this address' to pretend misdelivery, to return it to the sender with an 'Insufficiently addressed note or to cover part of the address with the postage mark.

Undercurrents equipment at the London International Exchange, the originating RT being then released.

Until recently, one could dial, either over a trunk access or by AC9 simulation, the appropriate routing code which gives GSC's access to the International exchange.

By by-passing the RT's in this way, the equipment did not 'screen' the country code that you sent and so you could enjoy full international operator status.

One example of this was Edinburgh, where the trunk routing code 51 5 gave you the International RTs in London.

Such direct methods are no longer available owing to considerable misuse, apparently by Post Office employees.

I t i s not obvious, by the way, why one would route the call via Edinburgh instead of going directly to London.

The reason i s that London i s sufficiently large to justify the provision o f special trunk exchanges to handle STD and ISD calls exclusively and the only routes onto these i s via originating RTs at the local director exchanges: there is no way to bypass these or even gain access to them incoming into London.

I t was Post Office policy to introduce ISD at provincial non-director areas only over the trunk transit network, so that i t was not until early 1 973 that the first of these (Cardiff) had ISD. Other exchanges soon followed but for the sake of illustration we shall consider Cardiff.

In September 1 972 the first circuits between Cardiff and the London International Exchange appeared. By dialling Cardiff trunks and then the code 12 one received a signal intended to initialise the transfer of digits, in SSMF2 form, from the Cardiff RT to the international registers. I f one's Blue Box was capable of sending SSMF2 one could respond to this signal, send whatever country code one pleased into the international registers, and again achieve international operator status. Those lucky enough to possess an SSMF2 Blue Box enjoyed the novelty of this new route to the rest of the world.

The Post Office was disconcerted at this traffic appearing as soon as the circuits were installed and very quickly (ie a year later) took steps to prevent such misuse. By the following February the Cardiff RTs had been programmed to accept 1SD calls and the service became available to the public.

(Coin boxes in Cardiff, incidentally, could not handle the high metering rate on calls to North America and so these were free of charge).

TELEPHONE SYSTEMS IN OTHER COUNTRIES Once a call has been set up to another country it i s possible to simulate the signalling employed over the international route and to explore the internal net-

work of the distant country.

The two most important signalling systems used over international circuits are known as CCITT4 and CCITT5.

In the signalling system CCITT4 digits are sent as four-bit binary numbers using two frequencies, 2400 H3 and 2040 H3, to represent 0 and 1 respectively. The control signals also use these frequencies. Digits are sent in response to signals received from the distant equipment, and the transit method of working i s generally employed between different countries. (The principles of the transit-working have been described in the first part of this article, as they apply to the internal trunk network in the UK). This signalling system i s unsuitable for use over satellite circuits since these introduce a return signal path of about 100,000 miles in length- corresponding to a time delay of some 600 milliseconds. In a'compelledsignalling system such as CCITT4 this delay i s added to the sending time of each digit which makes the overall setting-up time for a call for too high, bearing in mind the need for efficient use of expensive satellite circuits. CCITT4 finds i t s main application over shorter international routes, the main areas being Europe, South America and Africa.

Over intercontinental and satellite circuits the system CCITT5 is normally used. This i s a high speed signalling system. Digits are sent in multifrequency (MF) form similar to the SSMF2 system already described but using different frequencies. The CCITTS frequencies are the same as those used by the American Telephone and Telegraph Company (AT & T) for the North American internal signalling system, which i s very convenient for the Blue Box user. The two signalling systems differ only in the supervisory or control signals.

The simulation of CCITT4 was of great interest to the telephone enthusiast in the early days of ISD when the international RT's handing ISD traffic had access only to those countries to which ISD was allowed. For example, Russia was first reached in this way; a call to Switzerland (which was allowed) was made and then extended to Moscow via the Warsaw transit.

Since then, the equipment known as International Common Access (ICA) over which intcrnationdl operators connect calls, has become available for ISD traffic and most countries are now directly available to the enthusiast by the methods described above. With the availability of ICA interest in CCITT4 simulation has diminished.

Simulation of CCITT5 is simpler than for CCITT4 since one does not have to respond to backward signals and the procedure i s simpler. Furthermore, with

the addition of a single frequency, 2600 Hz, the simulator can be used within North America. I f one i s actually in North America then the procedure is indeed very simple and i t requires very little effort to make calls free of charge to almost anywhere in the wor This accounts for the tremendous popularity of Blue Box in that contin ent, the vast majority being primarily interested in saving money on telephone bills. There are only a handful of enthusiasts interested in telephones for their own sake.

I t i s possible to simulate the North American signalling system from the UK. The procedure i s best described by means of an example. Suppose you felt inclined to telephone an adjacent 'phone box via America you would proceed as follows. First set up a call to, say, the Philadelphia weather forecast. Having done this you would send a short burst of 2600 Hz. This is a 'tone on idle' supervisory frequency-that is, the application of this tone will 'clear down' the US internal circuit and i t s removal will reseize a circuit, the international circuit from the UK to the USA being unaffected. Next you would send (in MF form) the following digits-KP212183ST. The signals KP (Key Pulse) and ST (Start) are MF signals which must enclose blocks o f digits sent. This will connect you to area 21 2 (New York) and to the 'overseas sender' in that Gateway, the code 183 being i t s internal access code. When this equipment i s ready to receive digits it returns a continuous tone whereupon you send KP0441 838 7062 ST . The initial Lero i s a dummy digit, 44 i s the country code for the UK, 1 i s the area code for London and this i s followed, in this example, by the required London number.

I find the Australian telephone system much more interesting than the American. There are two in dependent trunk networks. Down Under-the MFC (multifrequency compelled), and the 2VF (two voice frequency), handling STD and operator-originated traffic respectively.

As far as I know, nobody outside of Australia has managed to simulate the MFC signalling, the difficulty being that the control signals are 'outband' (sent outside the normal 3000 H L voice frequency band). But provided that one i s incoming into Australia with operator status one can gain access to the 2VF network at centres such as Melbourne or Brisbane. This assumes that one knows the appropriate access codes. The 2VF network employs the AC1 signalling system, which uses two signalling frequencies: 600 Hz and 750 HL. Digits are sent in a similar way to AC9 signals but use the 600 HL frequency. The supervisory signals are

The fact th the cable companies will be separat from the programme companies i argued, provides a sufficient guarant against the extension of conglomerat control. This argument is, however, belied by the emerging pattern of in relationships between 'hardware' an 'software' interests. So far,British provisions for the regulation o f co mercial mass communications syst have conspicuously failed to addres the phenomenon o f intermeshing. I no longer sufficient to confine att to instances o f horizontal integra (as in the case o f the Monopolies mission report on film exhibition or to focus on the cross ownership of newspaper publishing and commercia broadcasting.

Secondly, it ensures that public needs take precedence over In the area o f programming, two key issues need to be considered: access, and accountability. Under the system proposed by the CTA, the extent o f public access to programme making facilities would be determined by the company holding the licence for the station.

The question f access, however, cannot be adequa y discussed or resolved in isolation. must be considered as part o f the ider question of accountability.
