Scott -
Do you always need a second dialer map to bring the second line up? What if
you are calling into a PRI that is on a rotary dial (single number).
Shouldn't that work with a single line and setting the calling to bandwidth at
128k?

Hi, Scott:
Thanks, the "dialer string" command may be the best choice for one
spid on PPP multilink, I guess.
I will lab it.
TIA'
