Setting Up the Modem
The unit has an internal modem for dial-in access to the menu-driven user
interface, as well as dial-out capability when an SNMP trap is generated. When the
modem will be used to dial out, Modem Directory phone numbers need to be set
up. Otherwise, simply configure or change dial-in access to the unit.
The modem port is already configured for connection to an asynchronous terminal
and dial-in access, with Port Use set to Terminal. However, additional changes
may be needed (see Table 4-25, Modem Port Options).

Modem Port
For dial-in access to the menu-driven user interface via Telnet, make sure Port Use
is set to Net Link, the IP address and subnet mask are entered if they are different
from the node’s, and that the Link Protocol is correct.
For dial-in access to the router connected to the unit’s COM port, make sure the
Communication Port’s Port Use option is set to Modem PassThru.
