DIAL PULSE RECEIVER |
摘要 |
<p>A dial pulse receiver forms part of a pool of receivers provided in common for a plurality of incoming junctors, each receiver output being tested by a computer every 14 milliseconds. The receiver prevents spurious signals shorter than a predetermined duration which are applied at its input from reaching its output. The receiver is also adapted to automatically detect the accidental connection of the AC mains to a subscriber line.</p> |
