Console port (outlined in red)
The unshielded RJ-45 RS-232 console DCE port (EIA-561) with the pin-out listed in the following table:
Ethernet port (outlined in green)
Shielded RJ-45 10Base-T/100Base-TX Ethernet port using pins 1,2,3, & 6. See MDI-X switch for hub or trans-
ceiver configuration.The following table defines conditions that occur when the MDI-X switch is in the out position.
MDI-X
The MDI-X push switch operates as follows:
•
When in the default out position, the Ethernet circuitry takes on a straight-through MDI configuration and
functions as a transceiver. It will connect directly to a hub.
•
When in the in position, the Ethernet circuitry is configured in cross-over MDI-X mode so that a straight-
through cable can connect the Model 3201 DSL modem's Ethernet port directly to a PC's NIC card.
Line port (outlined in yellow)
The RJ-11/4 DSL line port uses pins 2 and 3 of the RJ-11 port.
