Dallas (phone)
Dallas and Dallas LX are the names of two analog phone models that were offered by the Deutsche Bundespost and Deutsche Telekom in the 1980s and 1990s as a rental and later also as a purchase device.
background
Until the end of the 1980s, the Federal Post Office in Germany had a monopoly on the rental of telephone terminals. Something like model diversity first emerged in the early 1980s, when phones with different designs, colors, and functions were offered for rent. One of these models was Dallas or later Dallas LX . The less common model "Manhattan" (DFeAp 390) can be considered as a predecessor. Other compact telephones, the dialing device of which is integrated in the receiver, are, for example, the models "Kiel", "Kiel Hanseat", "Piccolo", "Spheron", "Spheron E".
The manufacturer of the Dallas series was Siemens , which offered a device with the same design as the Dallas under the name miniset 200 , but at that time only for private branch exchanges. Later, a very similar device was added under the name miniset 280 . It also had an LC display .
Naming
Key telephones with a keypad integrated into the telephone receiver were known to German consumers in the 1980s primarily from the television series Dallas , which was very successful at the time ; this is how the name came about. The device name of the Dallas is KTel 372 (compact telephone 372). In line with the “Premium” line of the Federal Post Office, the - better equipped - successor model was named Dallas LX . The device name of the Dallas LX is KTel 381 (compact telephone 381). Later appeared Ktel 381-2 . It had the same equipment, but differed in the programming: The first version has to be partially programmed using classic jumpers inside the handset, the second version using the programming sequences that are also common with later devices using the keypad. Optical distinguishing features: Version 1 has in the bottom row of buttons in the middle an unusual double arrow and a point on the switch button (Earth / Flash), Version 2 the widespread SET button (arrow points to the right in a diamond) and the later customary " R ".
Furnishing
The original Dallas model (convertible as a table or wall model) worked with pulse dialing and had redial and an illuminated keypad as well as an electronic bell instead of a mechanical bell. The device was available in the colors ivory, moss green, wine red and dark brown (not Dallas LX). The Dallas LX could be switched to the multi-frequency dialing method and had a memory for ten telephone numbers as well as a listening speaker. The keypad received a modified design.
price
The rental price changed over the years. In 1990 the monthly rental price for the Dallas telephone was DM 7.01 and the Dallas LX DM 7.81. For comparison: At the same time, the rental costs for a standard rotary telephone were DM 2.39, with a keypad DM 3.02 or one with keypad, ringer and redial 3.31 DM (excerpts from the first historical price list after the liberalization of the terminal market).
When connecting as a second or third device (with changeover relay), an additional approx. DM 1.60 was added. When the Dallas model (produced by Siemens ) went on sale, the price was around DM 160.
