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: AS5301 modem question [7:39917]
Michael, I have not worked on a 5301, only a 5300 so I will tell you what I know and maybe it will carry over. Since nobody else has any ideas, maybe this will help. In a 5300, the T1 card is a different card than the modem card(s). You said this is a quad T1 card so you should see 4 T1 ports on a card by themselves with maybe a couple of various other ports like console, etc. The modem cards, again on my 5300, had no ports to speak of. They were accessed directly via the backplane of the device. In order to gather modem information, type show modem at the enable prompt and this will output individual modem stats as well as tell you how many modems you have. If the 5301 is like the 5300, there are different modem options depending on the options you ordered. The 5300 could have up to 96 modems per card and held up to 2 cards for a total of 192 modems in a single chassis. Hope this helps!

AS5301 modem question [7:39917]
I have a 5301 that I'm trying to deploy. It has a quad T1 card in it. Is this where the modems are? It also has (2) AS53-CC2-DM cards in it. One of the AS53-CC2-DM cards has modems in SIMM slots 1 2. I'm not sure if they are 6 or 12's. My question is this, if they are sixes, does this mean I have only 12 modems total with this unit, or if they are 12's does this mean I have only 24 modems with this unit? If so, what good is the Quad T1 card? I just need a little help. Thank you.

Yes, it dials and handshakes but never initiates the ppp negotiation. The lights on both modems indicate a good connection, but then the connection just times out.

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.

Modem question
Hi Group When you use a 56K modem to connect to internet, you never achieve 56K. For example, sometimes it shows that the bytes sent at 48000 bps, sometimes 45000 bps, everytime it's different. So, where has those "bandwidth" gone to?? (--please correct if I'm wrong on this) So, can I conclude that a 56K modem is only theoretically 56K???
