IEN 1000
The IEN 1000 chassis supports one WAN and one serial port. The IEN 1000 chassis can
function as a simple bridge, bridge-router, or access device for a downstream controller or
terminal (SDLC, Bisync). Due to its design flexibility, the IEN 1000 chassis can have three
additional serial ports, an Ethernet or Token Ring router port, an eight-port UTP hub or an
eight-port Token Ring multiple access unit (MAU), data compression, data encryption,
integrated DSU, and 14.4Kbps dial backup.
