5 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 PulsAR radio that are useful for this purpose.

5.1 Telnet

5.1.1 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.

5.1.2 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 4. 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

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 4.
