Well,
This is taken from the ISDN CIM CD under configuring Dialer Profiles:
" When dialer profiles are used with PPP, a physical interface must have
encapsulation, authentication, multilink, and the dialer pool's
configuration settings. All other settings are part of a logical
configuration applied to the physical interface as needed for specific
calls. Dialer profiles support both PPP and HDLC encapsulation on the
physical interface."
The link that Chris sent does show that the PPP Authentication was not used
at all on the Physical Interface, it was used only on the Dialer interface,
Is this a Typo in the configs? or is it that the ISDN CIM CD is not accurate
in the description above?
I will try the configs in the example below and see if they work....
Any thoughts???????
Thanks
