the IRT-401
The IRT-401 is a compact, easy to install
ISDN router designed for small office and home applications. It provides you with the
ability to use it as a router, a bridge and a high-speed data connection for Internet and
Intranet at up to 128Kbps. The IRT-401 gives you the ability to economically connect your
LAN to the Internet, to a WAN and other LANs. Also provided is a built-in 4 port Ethernet
hub for your local LAN connection and the ISDN port gives you shared access to the
Internet, remote LANs and regular telephone services via the two analogue phone ports.

the IRT-401
- Features of the IRT-401
ISDN
- ST interface.
- Switched ISDN service for various switches worldwide:
EuroISDN(ETSI) switches in Europe
Germany(ETSI) switches in Germany
Australia switches in Australia
Taiwan switches in Taiwan
- Detailed accounting including, dialed numbers, disconnect
causes, frame statistics, connection usage and line uptime.
- Dial-on-Demand, auto dial-out triggered by outgoing LAN
traffic, auto disconnect due to inactive connection timeout.
- Multilink PPP and Bandwidth-on-Demand combine two B channels
to provide a full 128Kbps when extra bandwidth is needed beyond threshold. The B channel
drops back to one when network load lightens below threshold, which saves you unnecessary
connection charges. All connections are dropped if traffic is idle for more than a
pre-defined period
Ethernet
- 4 port 10Base-T (UTP) Ethernet Hub with unlimited LAN users.
- 16 user DHCP server for automatic IP assignment.
Internet/Intranet
- PPP (56K-64K), MultiLink PPP (MP) (128K), LCP, IPCP, IPXCP
and BCP.
- STAC LZS data compression with 128 KPBS -> 512 KBPS, 4:1
compression ratio on normal text file.
- Static or dynamic IP address assignment.
- Static or dynamic IP Route.
- Internet and Intranet connection profiles, allows one B
channel for Internet connection and the other B channel for Intranet connection.
Security
- CLID (caller ID).
- Call Back (hang-up and dial the caller).
- PAP/CHAP (PPP authentication protocol).
- Access List (filtering of packet’s bases upon IP address).
- NAT (Network Address Translation). Hides internal IP
addresses from outside world, with no need to change existing IP address assignments and
allows the subscription of single IP address account for the entire LAN.
- Packet Filtering. IP Access List
Network Management
- The IRT-401 can be managed using either the IRT-401 Network
Management System (NMS), a local console, a Telnet session.
- IRT-401 NMS runs on Windows 95, 98 and Windows NT platforms.
- Alarm warning on ISDN usage.
- Configuration files, save and restore.
Analog Services
- 2 RJ-11 ports for analog devices such as a telephone, modem
or fax.
- Multiple Subscriber Numbering (MSN) support; assign a
different telephone number to each analogue port, for routing specific calls, e.g. Fax and
Phone.
- Voice Call Preemption.
- Call Bumping.
Router Firmware
- Firmware upgraded through NMS (TFTP) and stored in FLASH
memory.
