GRP Ethernet Connection Equipment

The Ethernet port on the GRP has both a media independent interface (MII), 40-pin, D-shell
type receptacle and a media dependent interface (MDI) RJ-45 receptacle that are capable
of data transmission rates from 10 and 100 megabits per second (Mbps). (See Figure 3-15.)
Note
maximum usable bandwidth that is less than 100 Mbps; a maximum usable bandwidth of
approximately 20 Mbps should be expected from either the RJ-45 or MII connections.
Transmission speed is determined by the network to which the Ethernet interface is
connected and is not user-configurable.
