TB201(1FXS+1FXO)
Sharing High-Speed Internet Access
TB-series is a broadband sharing router that allows the PCs on your home LAN to share resources and files with online peers, and to access the Internet through your existing DSL/Cable Modem.

Joining VoIP Services
The two built-in standard phone jacks on the TB-series allows you to enjoy VoIP conversations while surfing the Internet. Since phone numbers given by Internet Telephony Service Providers (ITSP) can be assigned to either each phone port individually or to two phone ports at the same time, the TB-series is equivalent to two phone lines, free of extra charge.

Voice Quality Management
The TB-series enables network administrators to allocate network resources while guaranteeing Voice Quality of Service (QoS) automatically. By Voice Bandwidth Management, TB-series can guarantee the voice quality when internet access and VoIP service at the same time.

Lifeline (TB201 only)
The TB201 model with Lifeline support, allows users to use PSTN phone service and VoIP service at the same time. When ATA power down occurs, outgoing phone calls will be relayed to PSTN automatically.
