GEC No. 5100 Type
PRIVATE AUTOMATIC EXCHANGES
THIS small G.E.C. unit has an ultimate capacity for 25 lines, but can be equipped with as few as 10 extensions. It can be fixed on a shelf or table, but is particularly adapted for wall mounting, the backboard being provided with battens for this purpose. The apparatus is mounted on a metal framework hinged to the backboard so that it can be swung forward to facilitate inspection of the wiring. It is suitably protected against dust or damage by a wood cover.
The unit is very compact, being only 23" high, 16" wide, and 10.5" deep, and can consequently be fitted practically anywhere.
Telephone suitable for use with the No. 5000 type P.A.X. is the Cat No. 90 (DC Ringing). Only a triple conductor is necessary to connect the instruments to the switchboard.
