Directorate of Telecommunications

Here you will find a number of publications which the Directorate generated over the years and will give an interesting insight to the function and breadth of the organisation. They represent a tiny fraction of what was published over the years, so spend a while browsing through the archives.

In September 2014 this section was substantially reworked through necessity to simplify site maintenance and hopefully improve user experience.  Previously, when established in 2004 many visitors to this site were still using low-speed dial-up and so all documents had been scanned at lower resolution and displayed as gallery album images.  Current high speed broadband now enables documents to be downloaded quickly so the galleries have been phased out.  Where time permits I may rescan in higher resolution and replace some of the documents, such as the Intercom Magazines.


Annual ReviewsThe only copies I have to hand are for the period 1989-1991 and cover the name change from the 'Directorate of Telecommunications' to DTELS.  As with any organisation, the purpose of these reviews were to give a statement of how the business had faired during the previous twelve month period and what the management objectives were going forward.

If anyone has copies for other years, could they please get in touch with me via the feedback route.

CareersDuring its fifty-five year existence the Directorate recruited staff by various means, often through advertisements in national or regional papers covering the area where the vacancies existed. Sometimes, it would mount stands at recruitment or exhibition events that required additional careers information being published to hand out to persons interested in joining the organisation.

One such example is the six page A5 brochure in the following image gallery that was published in 1979. It was prepared by the Central Office of Information and Printed in England by Her Majesty's Stationery Office.

Recruitment Video (posted 17/12/2008)
During the 1980’s the WARC changeout programme in particular brought about a need to recruit additional staff to meet regional and centralised staffing needs.  It is thought that around the middle of that decade the Directorate commissioned an outside agency to produce a recruitment video for presumably showing at career days, seminars and  exhibitions.

The video was digitised from an original VHS tape with a protective box marked CFL VISION Chalfont Grove, Gerrards Cross, Bucks. SL9 8TN

Clive Wankling for digitising the original VHS tape and including his personal comment that from memory the young lady in the video is an actress and the men were staff from London Region or Central Communications Establishment (CCE) Harrow.

LU Exhibition 1971Information used in this section are articles drawn from a set of papers produced by the Directorate in 1971 for an exhibition held at Leicester University.

The comprehensive set of papers were intended to provide visiting members of the Police and Fire Services with a record of the talks and topics of then current interest and importance.

Guidance notes covering a range of topics were written and published by the Directorate for distribution to personnel who were involved with engineering projects.  As far as I am aware, the purpose of these documents was to provide Directorate or Customer personnel undertaking related projects with a source of pertinent technical information.

The documents listed below represent a tiny fraction of what was published over the years and hopefully give an insight to the scope and depth of topics covered.

WARC Aerial
Cheveley-Turnstile-RiggingThis document set out general principles of aerial engineering to be used as guidance when planning aerial systems at hilltop sites during the WARC changeout programme.

It was issued in April 1984 by the Radio Mast Design Team, which was then part of the MR4 Group based at Horseferry House London.

WARC Equipments
This document provided Directorate staff with technical overview and descriptions of the major items of mobiles and fixed equipments that formed part of the WARC changeout programme.  The document, which was issued in March 1986 by the Field Services Maintenance Planning Unit located at Weyhill, Hampshire, also contained an overview of the responsibilities and structure of FSMPU.

I believe the document was still being used as a source of reference by engineers involved with Public Safety communications almost 19 years later!
