1.1 Standard Nomenclature
The standard nomenclature for PULSAR carrier protection equipment is as follows:
Cabinet – contains fixed-racks, swing-racks, or open racks
Rack – contains one or more chassis (e.g., the TCF–10B)
Chassis – contains several printed circuit boards, called modules (e.g., Transmitter or Receiver)
Module – contains a number of functional circuits (e.g., Oscillator or Synthesizer)
Circuit – a complete function on a printed circuit board
1.2 TCF–10B Chassis
The TCF–10B chassis specifications (see Figure 3-3) include standard dimensions of:
Height – 5.25” (133.35 mm), requiring 3 rack units, each measuring 1.75” (44.45 mm)
Width – 19.00” (482.6 mm) Depth – 13.50” (342.9 mm)
Each chassis is notched for mounting in a standard relay rack.
1.3 TCF–10B Modules
The TCF–10B circuitry for the standard modules and the optional Voice Adapter, Electro-Mechanical
Output and Trip Test Unit modules is shown on the Functional Block Diagram in Chapter 7. Circuit
descriptions, complete with schematic diagrams and parts lists for each module, are shown in Chapters 9
through 19, along with sub numbers indicating the current revisions for each module, as follows:
