Basic Configuration Tasks
Establishing dial-in calls through terminal-server connections
MAX 3000 Installation and Basic Configuration Guide
5-9
Depending on how the terminal server has been configured to handle dial-in calls, it does one
of the following:
•
Displays the terminal-server command-line prompt, permitting the caller to use the
terminal-server commands that have been made available. This option is called terminal
mode. When in terminal mode, the user can initiate a PPP, CSLIP, or SLIP session.
•
Logs the user in to a designated host. This option is called immediate mode.
•
Displays a menu-style listing of as many as four Telnet and/or raw TCP host connections.
This option is called menu mode.
Terminal-server configuration tasks
To set up dial-in terminal-server functions, you need to set up the digital modems for call
handling, enable the terminal server, set up login procedures, and enable users to use the
terminal server to connect to hosts. Depending on your configuration, users can establish
connections through the terminal-server command line, be connected immediately to a host
after logging in, or select a host from a menu.
Setting up digital modems for call handling
To set up the MAX unit’s digital modems to handle dial-in calls, specify the following modem
characteristics:
•
Link Access Procedure, Modem Microm Networking Protocol (LAPM/MNP) error
control negotiation (the V42/MNP parameter).
•
The highest possible baud rate accepted by the far-end modem (the Baud Rate parameter).
•
Modem transit level, which is the amount of attenuation in decibels (the MDM Trn Level
parameter).
•
Modulation in 56K modems (the MDM Modulation parameter).
•
Whether the digital modem attempts cellular or conventional modem negotiation, and the
cellular modem gain level (the Cell First and Cell Level parameters).
•
Parity (the 7-Even parameter).
•
Packet handling for specialized applications (the Packet Wait and Packet Characters
parameters).
Enabling the terminal server and setting up login procedures
To configure the terminal server, access parameters in the Ethernet > Mod Config > TServ
Options profile. The terminal server is disabled by default. To enable it, set the TS Enabled
parameter.
By default, the terminal server does not require a login name and password for access to the
terminal-server CLI. To require a login and password, set the Security parameter. The
parameter permits the following types of access:
•
Full access, which prompts users for a name and password upon initial login and when
they switch between terminal mode and menu mode.
•
Partial access, which prompts users for a name and password only when they attempt to
enter terminal mode.
