• Framing PPP over ISDN (RFC 1618)
– The network adapter driver “AVM KEN PPP over
ISDN” is compatible with nearly all leading provid-
ers. The online service AOL is not compatible with
the Internet standard and thus can be reached only
with the CAPI dial-in software supplied by AOL.
– The driver software supports data compression ac-
cording to the STAC and MPPC standards.
– Multilink PPP (2-channel), also load-dependent
(threshold values can be configured).
• Short-Hold Mode
When an Internet connection is not actively in use, the
Short-Hold Mode clears down these connections after a
specified period in seconds and immediately reestab-
lishes the connection when needed. KEN! takes the
charge interval into consideration.
• PPP sessions can be captured with the Dr. KEN! diagno-
sis program.
• Packet filter for IPX and NetBIOS
A number of network applications constantly exchange
packets. When working in ISDN, this frequently can lead
to unnecessary connections. For this reason, KEN! con-
tains a number of special packet filters to intercept
such packets. Thus such actions as NetBIOS broadcasts
can be filtered instead of being transmitted via ISDN.
• IP masquerading / NAT
IP masquerading, or Network Address Translation (NAT)
on the KEN! Service PC fulfills two functions: protection
against unwanted access from outside, and re-setting
the internal IP addresses in a local network to a single
external IP address. Masquerading makes one “official”
IP address sufficient for communication between your
local network and the Internet.
– The IP host address to the KEN! Service PC is
192.168.114.254. It is assigned to TCP/IP permanent-
ly during installation.
