Multiprotocol FRADs/PADs and Switches

• FRAD/X.25 PAD with 24 async channels
• Protocols supported: Frame Relay, X.25, ISDN, RIP, RIP-2, HDLC, SLIP, MLPPP, PPP, async, Ethernet
  
• Standard IP encapsulation over Frame Relay (RFC 1490), X.25 (RFC 1356) or Ethernet
  
• Transparent bridging
  
• Automatic backup facilities
  
• Integrated ISDN terminal adapter
  
• X.25/Frame Relay multicasting
  
• Wide range of interfaces including CSU/DSU

• Allows construction of high performance, private X.25/Frame Relay networks or efficient extensions of public X.25/Frame Relay networks
• Enables secure migration from a terminal/host environment to a distributed client/server environment

The APS-24 is a high performance FRAD/X.25 PAD for access to Frame Relay or X.25 networks. Async traffic can be packetized directly over the Frame Relay network, or packetized over the X.25 protocol and encapsulated over a Frame Relay network.

The APS-24 is ideal in applications requiring a large number of async channels; in a heterogeneous environment combining async traffic and synchronous or LAN traffic; and in applications that require backup, bandwidth-on-demand or dial-in.

The APS enables secure migration from a terminal/host environment to a distributed client/server environment.
