Symbols Used in Figures

Modular jacks are shown by the triangle symbol. The 25-pair connectors are

indicated by shaded blocks. Generally, only one leg of an octopus cable is

shown. Unterminated wiring requiring cut down or other termination does not

show symbolic designations. The 103A Connecting Block is a typical

modular wall jack that provides cut-down connections for building (station)

wiring and a modular jack for connection to terminal equipment.
