STC TELEPHONE No. 7006 &7007
|The 7006 was a basic low-cost version of the BPO Telephone No. 706 made by
STC. It is believed that these STC 7006 telephones were also resold by
Modern Telephones Ltd. Modern Telephones had a deal with STC to sell
PO-approved P.A.B.X.s made by STC.
Almost identical to the GPO Telephone No. 706, it had a resistor network in place of the induction coil and a self contained microswitch/hookswitch.
Probably only used on PAX systems as transmission circuit was not up UK standards.
The 7007 model had a recall switch and 4 wire line cord fitted.
Two-tone grey is the only colour seen.
Ericsson's N1900E244 was similar.
