Chapter 1 Connecting to the UA5000

The UA5000 universal access unit supports local maintenance and remote

maintenance. The local maintenance is achieved through a serial port connection or a

local Telnet session. The remote maintenance is achieved through a modem dialing

connection or a remote Telnet session.

For maintenance, you must connect a maintenance terminal, which is a PC, to the

UA5000.

This chapter introduces how to connect a PC as the maintenance terminal to the

UA5000. The methods include:

Connecting to the UA5000 Through the Local Serial Port

Connecting to the UA5000 Through the Remote Serial Port

Connecting to the UA5000 Through the Telnet Terminal

1.1 Connecting to the UA5000 Through the Local Serial Port

You can connect a local PC to the UA5000 through a serial port, and log in to the

UA5000 using the HyperTerminal of the Windows operating systems.

Note:

The following sample procedure is carried out on Windows 2000 operating system.

1.1.1 Connecting the Serial Port Cable

Use a standard RS-232 serial port cable to connect a serial port of the PC with theserial port COM on the PVM card of the UA5000.

See Figure 1-1 .

Bits per second: 9600

Data bits: 8

Parity: None

Stop bits: 1


4/13



1-3

Flow control: None

Here the Bits per second , or baud rate must be consistent with that set on theUA5000. By default, it is 9600 bit/s. See Figure 1-3 .

Figure 1-3 Setting the properties of the serial port

Note:

Inconsistent baud rates often causes illegible display of characters on the PC. If this

happens after you log in to the UA5000, select another baud rate from the following for

the PC: 9600 bit/s, 19200 bit/s, 38400 bit/s, 57600 bit/s and 115200 bit/s.

1.1.4 Setting the Terminal Type

Select the menu File > Properties in the HyperTerminal window to set the terminalemulation type as ANSI or Auto detect .

Figure 1-5 Setting the line delay and character delay

Note:

The line delay controls the time interval of displaying each line, while the characterdelay controls how fast a character in a text is pasted to the HyperTerminal.

Insufficient line delay or character delay will lead to loss of characters.

1.1.6 Logging in to the UA5000

After setting the parameters, press Enter to display the system prompt. At the prompt,enter the user name and password on the HyperTerminal console.

The default administrator name is root , and the password is admin .

1.2 Connecting to the UA5000 Through the Remote SerialPort

For remote maintenance through a serial port, you must connect a modem to the

UA5000 and another modem to the PC. Through the modem dialup, you can maintain

the UA5000 from the PC. See Figure 1-6 .

The description is as follows:

The Modem at the UA5000 side is the called one.

The Modem at the PC side is the calling one.

When you connect the Modems, make sure that both the calling and the called

ones are standard Modems and support the AT command set.

Note:

Although the calling Modem can be either external or built-in, we suggest an

external one.

Modems of the same brand are recommended on both sides to guarantee better

performance.

1.2.1 Setting the Called Modem

Note:

The following configuration is just a sample, since the AT commands may vary with

different modems you use. Refer to the user manual of the modem for details in case of

inconsistency.

1-7

The UA5000 communicates with the called Modem only through the SD, RD and SG

leads of the serial port cable. Therefore, you must disable the flow control and ignore

the handshake signals on the Modem.

To configure a Modem, you need connect it to an intelligent terminal such as a PC. Thefollowing is a sample configuration procedure on a PC running the Windows 2000

operating system.

1) Connect the Modem with serial port 1 (COM1) of the PC using a serial port cable.

2) Connect the power cord and then power on the Modem.

3) (Optional) Install the Modem driver in the operating system.

4) Run the HyperTerminal program and select the port COM1 for the connection.

5) Set the port properties as: 9600 for baud rate, 8 for data bits, none for parity, 1 for

stop bits and none for flow control.

Note:

If there is no display on the terminal after you set up the connection, check whether the

no echo display function of the Modem is enabled at the previous setting. Enter the

command AT&F to restore the default settings of the Modem.

6) Check whether the Modem works normally.

Run the command AT&F in the HyperTerminal window to restore the default settings ofthe Modem. See whether the state code “OK” is displayed on the screen. If yes, the

Modem is working normally.

7) Enter the following commands in the HyperTerminal window. ATS0=1 //Set automatic answering (ringing once).

AT&D //Ignore DTR signal.

AT&K0 //Disable flow control.

AT&R1 //Ignore RTS signal.

AT&S0 //Force DSR at a higher level.

ATEQ1&W //Disable the modem from returning command response and execution

result, and save the configuration.

Note:

After you run the last command, no echo characters or command execution results

are displayed on the screen for any AT command. Most of the Modems can work

normally without any settings after power on.

To control the line rate between the Modems, you can run the AT$MB=9600 command to limit the highest rate at 9600 bit/s before you run the ATEQ1&Wcommand.

1.2.2 Setting the Calling Modem

Most of the Modems work normally without any settings after power on.

If the PC connects to the calling Modem through a non-standard serial port, disable the

flow control and ignore the handshake signals on the Modem. To do this, refer to

"1.2.1 Setting the Called Modem ".

1.2.3 Setting the Configuration Environment

Set the configuration environment as shown in Figure 1-6 .

I. Connect the called modem

1) Connect the telephone line to the LINE port on the Modem.

2) Connect the serial port of the Modem with the COM port on the PVM card using

the serial port cable delivered with the UA5000.

3) Power on the Modem.

II. Connect the calling modem

1) Connect the telephone line to the LINE port on the Modem.

2) Connect the serial port of the Modem to a serial port on the PC using the serial port

cable for the Modem.
