  1. Absolutely not! Some modems will listen for a dial tone and will not operate until it is detected. Now, there are hayes commands to disable this behanvior, but it may not support that command functionality. Moreover, the full line voltage may be needed, proper ringing, etc. A PBX can be had for pennies on the dollar if you know where to look. I'd go as far as to say that paying for one is even overkill; just head to your local University and see if they have some old Nortel boxes sitting around waiting to be decommissioned.
  2. Yep! In fact, I can do one better than that. My city provides free dial-up internet access to anyone. So, I can choose between dialing internally for access, or dialing externally for access as well, as we still have our landline connection. At which point it becomes rediculous. We get service to our house over fibre optic connection, which includes the telephone service through it. So if I dial out a connection, I end up with dial-up over fibre.
  3. Cool! It's not entirely a necessity for me, but I'm sure in the future it'll become useful. But, for file transfers, wouldn't an external SCSI drive loaded with files be much better? A heck of a lot faster. No multiple access, but for that you can use an Appletalk network and a file share.
  4. Hmmm. Lots of research that needs to be done. I'll probably end up doing that much later. For now, I'm going to test out this setup on my PBX system, and compare. I'll see how much that ISDN expansion costs, from what you've said it could enable some very cool stuff.
  5. I see what you're saying. The PBX that I've got can handle an ISDN expansion, so I'll keep my eyes open for one and also look into snagging an ISDN interface for my Cisco. It'll take some time for my budget, but if that ends up going well I'll post on the forums about it. Quite frankly I'm really only interested in "home" technologies. ISDN and T1 lines aren't what you'd have at home, and so I don't have the memories of those like I do with dial-up. It's also a limitation if my knowledge regarding the technologies involved. I know enough about standard POTS, but it's relatively sim
  6. Cisco does have ISDN and T1 interfaces, but keep in mind that when you start getting to digital connections, you start having problems in that the underlying infrastructure is a lot more complex than POTS. Those are both based on DS0 bundles, so while they're voice channels, I wouldn't know enough about actually breaking them out to single phone connections. One route I didn't end up taking (because I bought the LS-200) is that Cisco does make FXS modules. These provide phone line simulation, at least to the basic capacity of dial tone and dialing capabilities. Plus, they'll work
  7. Just chiming in because I have this setup at home. Mind you I got quite lucky with the finds needed to get it running. I use my Cisco 2821 router with a WIC-2AM installed for the ISP end of the connection. Those are both cheap and plentiful, and configuration is easy (if you've worked with Cisco gear before). At for the POTS network- I managed to find a MicroSeven LS-200 phone line simulator for a heck of a lot less than they are sold for online. Supports just about everything you could possibly want it to, but I don't have the DTMF option board. Oh well, I'm only doing one
  8. Bought a selection of hard drives, and I noticed on the bottom of one of the drives (ST51080N, as per the title) has some SMD caps that had slid off their pads. Upon further inspection, I found a total of three other pads with components missing. I was only able to find one missing component in the packaging, a 10K resistor. After careful inspection of the dust around my entire workspace, I wasn't able to locate the other missing components. From some photos of the PCB online, it looks like two missing surface mount ceramic capacitors. See attached. Marked in red are t
  9. Having some trouble with a new HDD I purchased for my SE/30. The disk appears to be perfectly OK, disk first aid says it's fine, Lido 7 can scan and mount it, and I've installed 7.3.5 on to it. It won't boot from it, so I assumed I needed to initialize it with Setup 7.5.3 Patched, but when the drive is selected under Setup, the "Initialize" option doesn't work. Spits out "Unable to prepare the disk for Initialization". Any tips would be appreciated!
  10. I had considered it, but doesn't the mod increase the thermal load on the analog board? It is an extra selling point, though. I'll probably just do it anyway.
  11. You know what? That was kinda fun! Not at all as difficult as I figured it would be. Just took my time and had some TNG on in the background. The glue was a little interesting to pull off, especially from those two caps glued down on their sides. But, as far as I can tell, it's all gone according to plan. I've taken a high resolution picture of the underside of the board and done my best to quickly paint some red circles on it to mark out the locations. Perhaps I missed a few, but I'll revisit this later and do a proper photoshop job, to make sure I've marked out all 47. http://imgur
  12. I was hoping for a map of the caps to the rear of the board. I've poked through that thread in the past. I suppose I'll just have to be careful and take it slowly. The board seems fairly robust, anyway.
  13. Finally got around to pulling out the analog board. Someone requested a picture? http://imgur.com/ypthvkP Otherwise, I've now got another issue- Does anyone have recommendations, or a "map" of which leads to desolder for the capacitors?
  14. Yup, a step up or two in voltage but no higher. Certainly with temp. I don't plan on keeping this one around, but I'd at least like to do a proper job.
  15. Yup, my thoughts exactly. It might be my first recap, but certainly not my first soldering job. That's some left over flux... I really ought to do a post-recap cleaning. It can't hurt, and I can leave it out to dry for a week since the analog board will be out for a week or two. I did look into that thread, and made the wire bridge near the edge connector. Still a fail, so it's looking more and more like an analog board issue... No photos yet, I didn't pull out the board on my days off. I might have time to do it after work, but I'm often too tired and just want to eat dinner + re
