IR-ETH Interface Module
IR-ETH is an interface module for RAD products, which is used for converting the
Ethernet (10BaseT or 10Base2) electrical levels to the TTL levels. It also converts
the Ethernet protocol to HDLC to enable long-distance transmission and avoid the
Ethernet collision limitation.
IR-ETH includes an internal, self-learning Ethernet bridge, which enables a high
performance link between two Ethernet segments at a low transmission rate. The
low-speed HDLC transmission is sent over the G.703 link.
Figure B-1 shows a typical application using RIC-E1 with IR-ETH module.
