  • Supports multiple concurrent protocols: IPCP, IPXCP, BCP
  • Standard Stac LZS compression with CCP
  • Optional strong encryption (IDEA) with ECP
  • Authentication with PAP or CHAP with periodical CHAP authentication for increased security
  • Dynamic DNS negotiation
  • Dynamic IP allocation, as server and client
  • Supports Leased Line and Leased B-channels backup and overflow over ISDN
