GPO Telephones - Type 711 Wall Mounted

Type 711 Wall Mounted

Initially with the 700 series, when a subscriber (customer) ordered a wall-mounted telephone, the attending fitter would have to requisition a standard Tele. 706L, a Bracket No. 6 and a modified, stainless steel, switch-hook assembly. On site the 706 would have its case removed, the front two feet knocked out, the instrument cord removed and the dial turned round through 180 degrees. The bracket was then screwed to the wall, the baseplate mounted on the bracket and the fixed wiring, having been led in via a hole in the baseplate, was terminated in place of the instrument cord. The two metal bezels by which the case was fastened to the chassis were removed and replaced by the new switchhook assembly. This had a bridging piece, like the carrying handle, but with two large hooks to stop the handset falling to the floor. If the instrument had an early dial bezel, carrying the letters and numbers, then this too had to be rotated 180 degrees. When reassembled, the result was an untidy compromise. It looked like what it was, an upside-down 706 with its handset hanging ungainly from the bottom and the curly cord dangling beneath. It was a relief to all concerned when all the above became unnecessary with the introduction of a purpose-built instrument.

Tele 711L

This was, essentially, a 706 base with a modified chassis and case. First introduced in 1961, it too could have either a steel or plastic base and wired or printed circuit internals, depending upon the manufacturer. It was supplied with the T-shaped Bracket no.6. The hooks on the top of the bracket located into the holes usually filled by the front feet. A single screw then secured the rear (bottom) of the baseplate to the bracket's upright. Only two rubber feet were left in place, to support the lower part of the instrument on the wall. There was no instrument cord, the fixed wiring being led directly in via the oblong hole on the lower left. The picture below shows one of the last 711s, having been made in 1968, the last production year. The 711 was superseded by the 741 shortly afterwards.

Famous quotes containing the words type, wall and/or mounted:

    “Time has an undertaking establishment on every block and drives his coffin nails faster than the steam riveters rivet or the stenographers type or the tickers tick out fours and eights and dollar signs and ciphers.”
    —John Dos Passos (1896–1970)

    “What harm cause not those huge draughts or pictures which wanton youth with chalk or coals draw in each passage, wall or stairs of our great houses, whence a cruel contempt of our natural store is bred in them?”
    —Michel de Montaigne (1533–1592)

    “So Lycidas sunk low, but mounted high
    Through the dear might of him that walk’d the waves,
    Where other groves and other streams along
    With nectar pure his oozy locks he laves
    And hears the unexpressive nuptial song
    In the bless’d kingdoms meek of joy and love.
    There entertain him all the saints above
    In solemn troops and sweet societies,
    That sing, and singing in their glory move,
    And wipe the tears for ever from his eyes.”
    —John Milton (1608–1674)
