Well, unfortunately v.90 modems (actually most modems in general) vary wide and far in initialization strings. It is rare to have a setup where you would hook 56K modems up to a 2500-series router and get 56K -inbound- connections. Your everyday POTS-using external 56K modem won't do this, you need to have the modems hooked up to a channelized T1 or PRI. Unless you have something like a USR Total Control hub which can accept calls over CT1 or PRI and still have actual serial ports on all the modems, it won't happen. So, there probably isn't a lot of gain in tweaking your init strings. Jason Young Access US(tm) Chief Network Engineer > -----Original Message----- > From: Francis A.
