Hello all,
playing around with ips0 I recognized that isp0 and LCP packets seems to be
responsible for open the line. A simple "ifconfig isp0" calls the remote
site. A tcpdump while "ifconfig isp0 delete -link1 down" has the following
LCP packets.
18:37:33.311450 LCP 19: Conf-Req(130), Auth-Prot CHAP/MD5,
Magic-Num=531cee06
18:37:33.311471 LCP 8: Term-Ack(130)
18:37:35.311977 LCP 19: Conf-Req(131), Auth-Prot CHAP/MD5,
Magic-Num=531cee06
18:37:35.311997 LCP 8: Term-Ack(131)
18:37:37.313015 LCP 19: Conf-Req(132), Auth-Prot CHAP/MD5,
Magic-Num=531cee06
18:37:37.313036 LCP 8: Term-Ack(132)
18:37:39.312304 LCP 19: Conf-Req(133), Auth-Prot CHAP/MD5,

18:37:39.312323 LCP 8: Term-Ack(133)
18:37:41.312595 LCP 19: Conf-Req(134), Auth-Prot CHAP/MD5,
Magic-Num=531cee06
18:37:41.312617 LCP 8: Term-Ack(134)
18:37:43.312998 LCP 19: Conf-Req(135), Auth-Prot CHAP/MD5,

and opened the line again. I do remember a LCP hack I used at former i4b
versions.
Do I have to use them again, is a hack for i4b 1 necessary and available?
Currently I dial into
a Cisco 3640 with IOS 12.x.
best regards Dirk
