Product Information

NB: There were a number of hybrid types between the 300 and 700 series. These appeared as 332s but fitted with a 700 series handset and cord. Among these were the 'intrinsically safe telephones', which had 323 style bodies of a sealed metal construction in a grey hammer finish. They were for installation in environments where there was a risk of fire or explosion from sparks, such as mines and chemical plants. The regulator could be removed from circuit, for customers not close to the exchange. This was achieved by turning it upside down, which substituted a shorting link instead of the components. In practice the unit was normally left in circuit. The downside of this plugin module was that if the telephone was dropped or mishandled the regulator board would become loose and fall out and cause the telephone to stop working until it was replaced by a technician. Compare this with the inside of a 746 where the regulator was integrated into the main circuit board. No. 740 are provided by removing the dummy button and fitting a Part 1/ ... 10/DBU/372 using the pin, Part 1/DPI/203, provided in the telephone.

Remove the single wire (sometimes two wires on some phones) from the 1uf capacitor (grey metal canister). These wires are be on the terminal Inside the circuitry is different in that the regulator components are soldered directly onto the printed circuit board, the switch-hooks and other components were miniaturised. No conventional wiring version was produced. The same colour options as for the General Post Office and one officer styled the Postmaster-General of England.' However, Charles II recognised none of This article's lead section may be too short to adequately summarize the key points. Please consider expanding the lead to provide an accessible overview of all important aspects of the article. ( May 2021) The 706 was manufactured to a GPO design, by several manufacturers. There were two basic designs: one with a modern printed circuit and another with a wiring loom. Other variations included: metal or plastic baseplates and the presence or absence of a metal carrying handle.

OUR MISSION AND VISION

These have an oblong circuit board inside. There are three distinct circuit boards. To identify which you have, Electrically identical to Bellsets 26/56 but with an all-weather case and externally mounted bell gongs, for use where much more volume was required. This was a 746 type telephone which could transmit MF4 signalling, also known as DTMF touch tones. These telephones could only operate to exchanges that could deal with MF4 but they were used on PABX systems that used MF4 for internal calls from the 1970s. The TXE1 exchange could handle MF4 calls as early as the late 1960s. This was however a unique prototype exchange, which served customers in Leighton Buzzard: otherwise customers did not have access to MF4 capable exchanges until later models of the TXE4 system came into service in the late 1980s.mid-19th century, right up to the late 20th Century whilst the telephone network was still a publicly run service. Within that Later extension instruments were: for extension 1 the Tele. 321 or 328 and for extension 2 the Tele. 326 or 327.

These were updated versions of the 200 type plans 5 and 7 but based on the 700 type telephone. It had a master station which was a 700 type telephone mounted on a plinth with buttons, 'The Planset 625'. The master station and the extension stations could call and speak to each other and also handle and transfer outside calls. The difference between a Plan 105 and Plan 107 was that the latter had only one extension; the former had two. On plans with the 'A' suffix, conversation between the extension and the exchange was private against the planset. On a Plan 107 both of the long buttons, on the front of the Planset 625, were connected together. Pressing either would 'buzz' the single extension.the sole carrier of post in the UK and forbade all competition. In 1870 GPO took control of Britain's telegraph network and A carrying-handle, in the form of a recessed finger ledge, is provided between the horns directly below the normal handset position. GPO 746 Push Button SIP The GPO 746 Push Button Telephone is one of the most popular telephones ever designed. A slice of British history FEATURES These were 700 type updates on the HTS 1 and HES 1 respectively. On both systems the main improvement over their predecessors was that the rows of call buttons were now arranged transversely instead of longitudinally. This meant that the basic 706 case styling only needed to be stretched forwards by 3inches instead of 8 as previously, on the HES. This looked neater and took up less space. Otherwise, both of these systems had the same facilities as their 300 type counterparts. The Tele. 162 Handset Micro Telephone, was the first UK phone to incorporate the transmitter and receiver into a single unit, 'The Handset', which had not been used on telephones in the UK since the very early metal and wood cased models, and the BPO preference for a separate transmitter and Bell receiver, as on the Tele. 150 and Tele. 121.

The ultimate task of the Tele. 710L was that of being transformed into an Extension Station of a House Exchange System No.3. (see above) Nos. 740 and 746 are identical with those of the Telephones Nos. 710 and 706 which are described in A1063 and A1060 respectively. This Instruction describes only those parts particular to the Telephones The original GPO Telephones were produced by the General Post Office in the UK from the advent of the telephone in the Nos. 740 and 746 shows one change from that of the Telephone No. 706. The brown wire from dial terminal D3 is taken to telephone terminal T3 instead of gravity spring 5. This short-circuits the transmitter when the dial is taken off-normal and prevents surges in the spark quench circuit passing through the transmitter.The main instrument could make and answer exchange calls, talk to and transfer calls to the extension(s). The extensions could call and talk to each other and the main instrument, but could only make external calls if a request to the "operator" at the main instrument, for the exchange line to be switched to the extension was honoured. The telephones, as issued, have the aperture for the press-button(s) closed with a dummy button held in place by a clip. When a press-button unit is fitted the dummy button and clip should be secured within the telephone for subsequent refitting. Cromwell's laws so issued a very similar act in 1660, which confirmed the formation of The Post Office. The law made the GPO This comprised, up to, five stations, all of which could call one another and make, answer or transfer calls.
