ISDN router - Computer Definition
A device that enables several users on a network to access the Internet via ISDN. Also known as an ISDN LAN modem, it contains a BRI ISDN port and an Ethernet port. It may also provide several Ethernet ports, which lets it serve as a central Ethernet hub for a small workgroup. Access to the unit for configuration and monitoring is typically done via a Telnet connection or Web browser or both. See modem router and ISDN.
