Chapter 14. ETHERNET IP
MODULE – CLI
AND
TELNET
OPERATION
14.1 Overview
The CLI (Command Line Interface) is a user menu system that facilitates configuration,
monitoring and control, over a user-supplied terminal emulator (e.g., HyperTerminal) or Telnet,
of the CDM-570/570L and its Ethernet IP Module Interface.
14.1.1 Interface Access
1. The IP Module does not allow concurrent access to the menu via Telnet and
the Console port. If a user connects via Telnet, the IP Module automatically
disables the Console port for the duration of the Telnet session. All menu
pages allow a Telnet logout to end a Telnet session. Also, the IP Module
automatically ends a Telnet session after a period of inactivity (configurable
from 1 to 60 minutes).
2. Any changes made to the base modem and IP Module will be lost if the IP
Module is reset or loses power unless the changes are saved to permanent
storage. This applies to all of the IP Module and base modem parameters.
The parameters can be saved by selecting “S”, available on any CLI/Telnet
Menu page.
3. As of Modem Firmware Ver. 1.5.3, all parameters for the modem are stored
in the IP Module parameter file. This provides a single file to store the entire
contents of the modem.
4. As of Modem Firmware Ver. 1.5.3.1, all parameter changes made for the
modem or IP settings will automatically be saved by default. This applies to
any changes made from the front panel or any other user interface
(Web/CLI/SNMP, etc.) This feature can be disabled in Maintenance/Database
Operations.
For connection via a Terminal Emulator: The user PC should be physically attached to the
Console port of the IP Module. The terminal emulator should be configured to match the Console
port setting. The default Console port setting is 38,400 bps, 8 data bits, no parity, 1 stop bit and
no flow control.
