[Project Telephone]

Hey all,

Show you today a Deutsche Bundespost (German federal post office), payphone called (Clubtelefon 1) Clubtelephone 1. The Clubtelefon 1 (also called TMünzFw88) was introduced in June 1987. The housing is similar to the normal coin telephones at that time, but the club telephone manufactured by Landis & Gyr Communications Deutschland GmbH was smaller (height 545 mm × width 220 mm × depth 225 mm) and - instead of the gray hammering of the devices in telephone cells Colors brown-beige. In the 17 kilogram club club only three different coins could be inserted into two existing coin slots (1 DM and 10 with 50 Pfennig). The Clubtelefon 1 could not be converted to euro coins. [7] The coin test was carried out mechanically and electronically; A four-digit liquid crystal display showed the credit. The after-delay call occurred acoustically 10 seconds before the end of the credit and the display flashes. A re-selection was possible according to short attachments of the listener (shorter than 1.5 seconds). In addition to the pulse dialing method, the multi-frequency dialing method should also be available, but this has never been used; The plug on the board for the MFV extension board was only installed in the first devices, later the place remained unassembled. The key selection block was made of metal. Incoming calls were possible. An integrated test program with a display of the defective module showed a possible fault to a service technician. The supply current on the connection cable had to be at least 17 mA; If necessary a power supply could be retrofitted, but this was never introduced by the post office. The magnetic field protection necessary due to the position of the optional power supply directly next to the main processor was later omitted. The Clubtelefon 1 could be operated at a temperature between -30 ° C and +55 ° C.

Approved traffic options were local calls, local and self-service calls (domestic, "SWFD"), incoming calls, SWFD calls to the European countries with prefixes 003, 004 as well as to Turkey 0090 and telephone calls abroad (domestic / foreign). Telegram reception, telecommunication services, FernVSt Hand (domestic), coastal radio, FernVSt (foreign countries) and SWFD calls (abroad) were blocked.
