1 GENERAL INFORMATION
The DS73 and the DS73TP peripheral communications module supports remote access to TCP/IP Ethernet networks
by using the DS-Series Data Switch with a modem module installed. Remote users can dial into the DS-Series unit
and connect to network hosts from anywhere at anytime. Both remote in-band and out-of-band management is
available by using one DS-Series data switch. Use the DS73 module for in-band network management. And use the
DS74, EIA-232 module for out-of-band management.
Remote workstations and PCs connect to the DS73 using a dial-up PPP session. This offers dial-up users a low cost
IP network link suitable for remote access to the network.
IMPORTANT: You should determine what types of peripheral modules you have installed in your DS-Series unit in
addition to the DS73 peripheral module. You should familiarize yourself with the various operation modes of the
installed peripheral modules. A brief operational description of each peripheral module is provided in the DS-Series
Owner’s Manual.
