#145854 - Pulse Dialling Responding to: ???'s previous message |
Steve M. Taylor said:
Is pulse dialling still do-able ? Yes, if you're on a direct BT exchange line; For anything else (Cable, 21CN, whatever), you'd have to RTFM to check... For the other systems, there's probably some sort of adaptor box that provides a "POTS-like" interface to your phone, and converts this to whatever other signalling the rest of that network uses - so it all depends on whether the adaptor box supports Pulse dialling... aka "Loop-Disconnect", or "LD" for short |

Beware! | 01/01/70 00:00 | |
about that -48 volts ... | 01/01/70 00:00 | |
i did, OUCH | 01/01/70 00:00 | |
the key is to remember it\'s a current-loop | 01/01/70 00:00 | |

Not really surprising. | 01/01/70 00:00 | |
Not necessarily | 01/01/70 00:00 | |
Here, it detects both | 01/01/70 00:00 | |

Why is that the key?? | 01/01/70 00:00 | |
It's the key to understanding it | 01/01/70 00:00 | |
Sorry, but I cannot see the evidence | 01/01/70 00:00 | |
Your circuit diagram shows it adequately | 01/01/70 00:00 | |
