The GRP has the following two types of Ethernet connections
RJ-45 media-dependent interface (MDI)
•
40-pin, D-shell type media-independent interface (MII)
•

To transceiver,
repeater, or DTE
You can use either Ethernet connection, but not both at the same time. Two LEDs
on the GRP front panel indicate which Ethernet port is active. Each connection
supports IEEE 802.3 and IEEE 802.3u interfaces compliant with the 10BASE-T
and 100BASE-TX standards.
The Ethernet port can use either unshielded twisted-pair (UTP) or shielded
twisted-pair (STP) cables. Shielded twisted-pair cables are recommended for sites
at which extremely high immunity to noise is required.
