6.8 Interoperability
Because it supports the interoperability standard PPP over ISDN and
numerous other standards in the PPP suite–specified in RFCs (Re-
quests for Comments)–the ISDN Access Server can connect to all
systems that conform to these standards.
In addition to the RFCs, the AVM Access Server also implements new
draft PPP standards that have not yet been adopted by the IETF. Such
advanced features include a number of spoofing techniques devel-
oped by AVM, which are implemented in the AVM Access Server based
on the PSCP draft. The AVM Access Server supports the following RFCs
and RFC drafts:
sha Secure Hash Algorithm 1 (SHA-1)
md5 Message Digest 5 (MD5)
all The SHA-1 and MD5 hash algorithms are proposed to the remote
system in that order
lzjh LZJH (RFC 2395)
deflate Deflate (RFC 2394)
lzs LZS (RFC 3051)
no Do not use payload compression
pfs Require perfect forward secrecy
no-pfs Do not require perfect forward secrecy
