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.
