Perhaps this will help
A Shiva AccessPort tries SPAP for authentication first (default), but this is not
NAK'd
correctly by the Cisco device, which expects CHAP.
Solution:
Set the Shiva AccessPort to use only CHAP as the authentication protocol.
1. Go into admin mode, and enter the following commands:
net isdn2 se
listener
PAP: no
CHAP: yes
SPAP: no
My CHAP identifying name : lokal host name
Simultaneous two way authentication: no
