Re: Modem question [7:70392]
you can connect to a serial if that serial has async capability... do sh ver in your router like: sabenash ver .. cisco 2520 (68030) processor (revision M) with 14336K/2048K bytes of memory. .. 2 Low-speed serial(sync/async) network interface(s) == you see this serial interface can work in both sync and async... however the default is sync... so make that corresponding interface async with the physical layer async command.. this command will create a line x as well...

Not all Serial interfaces support this, but the command that kicks the process off is physical layer async http://www.cisco.com/en/US/customer/products/hw/modules/ps3129/products_ tech_note09186a00800b1502.shtml All the best!

Re: Modem question
Hey Mari, You will never see a 56000 bps connection! I think the fastest allowed by telco due to line parameters is 53300. I usually get 48000 or 51000. But after a sustained heavy rain, I only get 16000 or 28000 and once only got 9600. Must have a crack in the insulation on my line between my home and the CO. If you consistently get a low connection speed, you probably also get noisy voice connections!

Re: Modem question
You would be correct. If you read the fine pritn on the modem box, it even says this. ... US Robotics "While Download speeds of 56k are possible, FCC limitations enforce a download limit of 53.3K" In Real Life, 90% of the universe is too far from the local CO to get a real speed better than 33.6. Add into that the limitations of Software controlled modems, and most people would be impressed by a 56k Leased line connection, because it would "feel" twice as fast as a dial-up. This accounts for much of ISDN's continued popularity.
