Fenny Stratford Repeater StationApparatus Room |
|||||||||
The Apparatus Room was on the first floor. It was here that all the underground cables were brought in and terminated onto racks equipped with trunk test tablets. These had removable links which enabled the cable pairs to be disconnected from the repeater equipment in order to allow testing to be carried out. The test tablets were cabled away to the primaries of the line transformers and the secondaries of these were cabled to the repeater distribution frame (RDF). The RDF provided a flexibility point which allowed any cable pair to be cross-connected to the repeaters and other equipment as required.
The repeaters and other associated equipment were built on standard 19'' panels and mounted on 10'6'' high racks, the bottom of which were embedded in concrete. A maximum of five repeaters could be accommodated on a rack. Also mounted on each rack was a jack field to enable the circuits passing through the repeaters to be intercepted so that monitoring and measuring of levels could be carried out. Panels equipped with fuses in the relevant supplies were also mounted above the jack field. Some racks were also fitted with volt meters and ammeters to enable the checking of the high and low tension supplies. All the repeater apparatus was supplied and installed by the Western Electric Company.
