} If I recall from when Mindspring was at ALE last year,
} their statement was "All of our ports are set to 115K,
} ISDN or analog"  so whatever advantage you get out of
} compression is fine up to 115K.
} 
} As for 128K, the way ISDN works it takes 'two telephone
} calls' to get a 128K connection, then the two B channels
} are 'bonded'.  Well my understanding of the problems with
} this are #1) most of the existing bonding protocols are
} currently not compatiable and #2) both calls going thru
} the hunt group have to wind up on the same physical ISDN
} terminal server so they can be bonded.
} 
} Multilink PPP does work, but AFAIK dosn't address #2.  
} The solution for a ISP is to give you a private number
} to dialin to so you are always going to get the same 
} two ports on the ISDN termserver.

This must be where I got the info about 'dedicating' a TA to your line.
