ISDN Ethernet Router with S/T Interface
and Built-in 6-port 10Mbps Hub

TW-H6W1IR [ISDN Ethernet Router] The TW-H6W1IR is a multi-function ISDN router that has 6 built-in Ethernet hub ports, which provides small and home office users an all-in-one solution for Internet connection. The built-in hub feature saves users the time and trouble of purchasing and installing a separate hub by allowing 6 separate workstations to directly connect to the ISDN router. The password protection for the system management terminal, PAP, CHAP, and MS-CHAP protocols are supported for remote access users. Also, the TW-H6W1IR is concen-trated on easy-of-use, Internet/WAN security, and the cost-effective use of ISDN services. Local and remote Telnet allows simple setup and troubleshooting.
