Quote from: bellsystem on June 28, 2017, 06:05:34 AMSxS (Strowger) switches are my favorite but it would not be practical for a primary PBX... it would be impossible to hook it up to the PSTN directly anyways

Quote from: bellsystem on June 28, 2017, 07:52:07 AMWow, thanks!Would you mind directing me to any diagrams or information about these systems online?The thing is I would need * and # functionality on those TT phones (conference calls) so I would still need to get that to be able to work somehow.Also, I would have a few key systems within the PBX.
Quote from: bellsystem on June 28, 2017, 08:48:55 AMThe Bell System introduced 3-way calling for analog systems (even though it required a digital switch).Just to make myself clear - I have nothing against digital SWITCHING. The PSTN is now 100% digitally switched. It's just the TRANSMISSION I'm concerned about.
Quote"How would you accomplish DID with Strowger switches directly connected to the PSTN? I'm not into crossbar much because it doesn't have the same meaning to me as Strowger. I like seeing the switches move up and down."If this is accomplishable, I just might go that route! But I'm not sure how you would set it up. A SxS system is literally just switches. What would the outside lines each connect to. And when a phone dials 9, wouldn't they all attempt to reach the same phone?"
