MAIN FEATURES

Network Services & Security:

• QoS (TOS, COS, Diffserv)
• Fair Queueing (per TCP session; per src or dest IP address); weighted FQ
• SNMP
• TELNET client & server
• SSH client & server
• SSL
• NAT & PAT
• IP Access Lists
• IP Source Routing
• IP static and dynamic routing (RIP2-OSPF)
• Dynamic Speed Limit (in order to avoid overruns while transmitting voice packets, the Dynamic Speed Limit temporarily reduces the outgoing throughput to safe values, and leaves full throughput otherwise)
• NTP (Network Time Protocol) client e server
• DNS server resolver & relay
• DHCP server & relay
• FTP server
• PPP & PPPoE, RAS server
• HTTP server
• POP3 & SMTP Server
• XTP (X25 over IP)
• Tunneling IP SEC / IKE and PLINKE (tunnel for voice and data over IP)
• Multi Link: Channel Bundling to increase total bandwidth
• Redundant Link: ABILIS duplicates and sends its packets out over two links, hence significantly reducing the probability of lost or bad packets

Voice Services:

• VoIP<->ISDN Gateway
• PABX:
  • CLI presentation
  • HOLD and TRANSFER
  • Pickup
  • multicast ringing
• IAX-2 (VoIP trunking together with Asterisk Soft PBXs and IAX-phones)
• SIP server and client
  
• H.323 Gateway and Gatekeeper
• Routing based jitter compensation for FAX and VOICE calls

Smart ISDN BACKUP:

• up to 8 simultaneous calls per 64k channel
• reliable proof of the main link integrity by the exchange of test-packets
• the switched backup link stays on only if there are active calls and only until the main link is down

Multi Link: Channel Bundling to increase total bandwidth

Tunnel Encryption: Advance Encryption Standard RC6 with 256bit key

SSH Encryption: DES, 3DES, Idea, Blowfish
