6 NETWORK MANAGEMENT
The radios operate as part of a network environment with many devices. Whether operated by an
Internet Service Provider (ISP) or the Information Technology (IT) department of a business, there is
often a need to supervise and manage the network from a central Network Operations Center (NOC).
This chapter describes the features of the AR24027 that are useful for this purpose.
6.1 Telnet
6.1.1 General
Telnet, which stands for Telecommunications Network, is a protocol that allows an operator to
connect to a remote machine giving it commands interactively. Once a telnet session is in progress,
the local machine becomes transparent to the user, it simply simulates a terminal as if there was a
direct connection to the remote machine. Commands typed by the user are transmitted to the remote
machine and the responses from the remote machine are displayed in the telnet simulated terminal.
6.1.2 Starting a Telnet Session
In order to start a telnet session with a radio you first need to configure the radio with a unique valid
IP address. This is done with the ip-configuration command described in section 5.6. This initial
configuration must be done using either the RS-232 console port or the ECON program.
Once the radio has an IP address, you must start the telnet application at the local machine and
establish a connection with the IP address of the radio. If the local machine is a PC running
Windows, you can start Telnet through Hyperterminal as follows:
1. Start the Hyperterminal application (in a typical Windows installation Hyperterminal can be
found from the Start button under Programs/Accessories/Communications…)
2. From the File menu choose New Connection.
3. In the Name field enter any name you wish and press the OK button. This will open the
“Connect To” window.
4. In the last field, titled “Connect using:”, select TCP/IP (Winsock). The fields above will
change to Host Address: and Port Number:.
5. In the Host Address field, type the IP address of the radio, then press the OK button.
6. TCP will now attempt to connect to the specified device. If successful the radio will request a
login name with the prompt login:
7. Type public followed by the Enter key
The radio will now display its prompt command and you may type any commands as described in
section 5.
If after entering the public login name, the terminal displays the message “Login Failed”, this may be
due to the radio being configured to be managed from only some specific IP addresses. This is
explained in the following section.
