A TEST BUS DISTRIBUTION SYSTEM OF TDX-10

摘要

The apparatus includes a (16x4)x2 relay matrix group (15) having a relay driver. A relay matrix column decoder means (14) and a relay matrix row decoder means (17) are connected to the relay matrix group (15), and data buffer means (13,16) are connected to the relay matrix decoder means (14,17) respectively. A delay and control signal generating means (12) is connected to both of the data buffer means (13,16), and an address decoder means (11) is connected to the delay and control signal generating means (12). With the apparatus, a subscriber line to be tested can be automatically connected to the testing equipment, and a manual testing mode is also provided.
