network interface.
Link-Status
The current link status of all models is indicated by the Error
LED on the device front panel. Flashing at a rate of approx. 1
second indicates that there is no connection to the hub or that
the connection is faulted.
3.1.1 10/100BaseT on RJ45
The LAN-Modem has a 10/100BaseT network interface on a
shielded RJ45 connector. The pin assignments shown below
correspond to an MDI interface, so that the connection to the
hub or switch is made using a max. 100m long 1:1 shielded
patch cable.
