Bridging Terminal server

Product Overview :

TEAMLINK Bridging Terminal server is a versatile and high performance system that provides the 4/8/16 asynchronous RS232 Ports, One Console Port and Four Port Built-in Ethernet switch. It enables the users to remotely login the system using the rlogin and Telnet and TCP/IP Network over the V.35 Interface

Features :

  • Connecting the RS232 Terminal Ports using the TCP/IP protocols
  • Connecting through the Telnet and Remote Login using the TCP/IP Protocols over the 10/100 Mbps Ethernet Interface
  • Connecting the Remote Host systems after power on using the implicit connections
  • 15KV ESD Protection on each Terminal port for the Rugged Operating conditions
  • Configuration and status Monitoring from menu driven console and Telnet port with the multiple telnet sessions
  • 1500V AC Isolation protection on each Terminal port
  • Supports Answer back codes on each terminal port
  • Supports Answer back code Enable and Disable Facility for each Terminal Port
  • Supports TCP Client and Server, Telnet client, Server and Rlogin client Options
  • Implicit, Fixed, switched Mode of configuration on each Terminal Port
  • Domain Name Service Facility enables flexible host name to IP address mapping from DNS servers
  • Facility to switchover from One server to another server in case of failure
  • The unit works in PRS/UTS environment of Indian Railways
  • The unit can be used as a local Terminal Server for RS232 and Ethernet DTEs or as a Remote Terminal Server with Bridging for RS232 and Ethernet DTEs
