Introduction
The LAN-Modem permits devices that require dial-up
modems for communicating to use the Intranet or
Internet instead of the telephone system. On a serial
interface, the LAN-Modem behaves in a way this is
compatible with standard modems for the telephone
system; the only difference is that the dial-up number is
replaced by an IP address.

W&T Connections and Displays
2.1 Ethernet connection
The location of the LAN-Modem must be selected such that
on the network side a maximum cable length of 00 meters
is not exceeded.
For the network connection, an IEEE 802.3 compatible
terminal on a shielded RJ45 plug is provided on the front
panel. With a shielded patchcable the LAN-Modem can be
connected through here to a hub or switch. Pin assignments
conform to a standard MDI interface (AT&T258), so that you
can use here a : cable with a length of max. 00 meters.
1 = Tx+
2 = Tx-
3 = Rx+4 = nc 5 = nc 6 = Rx-
7 = nc
8 = nc
RJ45-Buchse (Belegung AT&T256)
Depending on the LAN-Modem model, the following
standards are supported:
10BaseT (Typ 5 210, 5 610)
These devices operate conformal with the 0BaseT
standard at 0MBit/s. It is also possible however to link
into a 00BaseTx network using an autosensing hub or
switch. Such an autosensing component automatically
adjusts to the transmission rates supported by the
terminal device.
10/100BaseT autosensing (Models 5 220, 5 620)
These devices support both 0BaseT as well as the
00BaseTx standrad at a bit rate of 00Mbit/s and offer
full-duplex transmission. Switching between the two
network speeds is done using the autosensing function
of the LAN-Modem according to the capabilities of the
hub or switch used. The prerequisite for operating at
