If I remember correctly, and I have no proof of this, PAP authentication will b
ring up 2 channels if they are available, authenticating both ways. CHAP will
allow for the use of only one channel.
I couldn't find anything on Cisco or in the RFC's that state this and unfortuna
tely I do not have access to an ISDN switch at the moment.
HTH,

Hello,
It is from my ECP1 binder / Ex.3 (IP over isdn).
Question 1. (it is ex. 3.1.1. in ECP1- just in case)
Make sure that only one B channel is activated when a call is placed.
How to do that? I have overall answer to the exercize , but I am not sure
what is the answer to this particular question.
Question 2. In the answer it has 2 dialer strings on calling router . Why
would I need 2 strings?
dialer-string 5552xxx
dialer-string 5552yyy
Thank you.
Vadim.
