| 摘要 |
The invention comprises a main distribution arrangement for a telephone exchange, including a rack (1); several subscriber-related connectors whose positions are affixed to the rack, coordinated to one or more connection terminals (2a); and several external connectors that belong to telephone exchange-related line circuits, also affixed to the rack and coordinated to one or more connection terminals (3a). Said connection terminals are situated close to one another, and are arranged, with required main distribution conductors (23), to connect selected subscriber-related connectors with selected telephone exchange-related external connectors. A predetermined number of telephone exchange-related line circuits are coordinated to a block (10). Each block (10) can be inserted into and removed from the rack along parallel bars (11, 12). The leading edge section (10d) of a block (10)-as determined when the block that is being slid into the rack-presents line circuit-related external connectors, coordinated to one or more connection terminals (10e, 15a) that, when a block (10) is fully inserted, interacts electrically with said telephone exchange-related external connectors, coordinated to one or more connection terminals (3a).
