Signal distribution installation

A wiring concentrator comprising:

• a first connection terminal (43) adapted to receive a television signal distribution cable (12);
• a second connection terminal (48) adapted to receive a telephone network cable (13);
• a plurality of third connection terminals (49A–49H) each adapted to receive a local area network cable (49′);
• a first connector (50) adapted to receive an active electronic unit (16) for processing television signals;
• a second connector (52) adapted to receive an active electronic unit (18) for processing telephone signals;
• a third connector (51) adapted to receive an active electronic unit (17) for processing local area network signals;
• a printed circuit board (53) to which each of said first, second and third connection terminals (43, 48, 49A–49H) and each of said first, second and third connectors (50, 52, 51) are connected, said printed circuit board (53) connecting said first connection terminal (43) to said first connector (50), said second connection terminal (48) to said second connector (52), and each of said third connection terminals (49A–49H) to each of said first, second and third connectors (50, 52, 51), and
• a chassis (54) on which said printed circuit board (53), each of said first, second and third connection terminals (43, 48, 49A–49H), and each of said first, second and third connectors (50, 52, 51) are mounted, which chassis (54) includes a housing (56, 57, 58) for each active electronic unit.
