D-Link DI-1750 Reference Manual page 416

Model Name
CRTP is applied to PPP links. However, if the opposite terminal PPP implementation support only
CTCP of RFC1144, IPCP of RFC1144 can be used in the same. But if you apply CTCP on FR and
HDLC link, cisco-format will adopt CTCP of RFC1144, iphc-format will adopt CTCP of RFC2507, and
passive show our CTCP is determinded by CTCP message format that sent by opposite terminal.
