A.10 ET100R 10/100Base-TX Ethernet Router
When the ETU-01A is ordered with an ET100R Interface,
the unit is not only an access unit for E1, but also becomes a
high performance router for 10Base-T or 100Base-TX Ethernet
LAN connection. The ET100R utilizes standard pin out on one
RJ-45 connector, providing connection to Ethernet (10Base-T)
or Fast Ethernet (100Base-TX) networks over UTP (unshielded
twisted pair) cabling.
Configuration of the router is beyond the scope of this manual.
Please refer to the CDROM based instructions that are included
with the router module. The ET100R router module is
configured with the CLI Telnet or Web based GUI. The user
manual and quick start guide are included on the CDROM. Alternately the router may be
configured via the RS-232 console port. A special cable must be used to connect to the modules
DIN connector. Pinouts are provided below for reference.
