PRODUCT FEATURES

• Legacy protocol transport
  Serial and synchronous/asynchronous ports are ideally suited to transport legacy traffic across a TCP/IP network, facilitating network convergence and eliminating costly separate leased lines for this traffic.
• Dial access server
  Asynchronous HWICs can connect to external dial modems to provide low-density dial access servers.
