Overview

The P-871M is a VDSL modem in CPE (Customer Premises Equipment) mode and can also act as CO (Central Office) equipment. CO equipment is where home and office phone lines terminate and connects to a much larger switching system. In the following example, you can build up a VDSL bridge connection between two P-871Ms.

1 Hardware Connections

You can set the P-871M to work in either CO mode or CPE mode. Follow the procedure below to complete the hardware connections.

1.1 CO Mode

CPE

1 Set the CO/CPE switch on the rear panel to the CO side. 2 Use the included console cable to connect the CONSOLE

port to your computer’s COM port for configuration.

3 Use the included yellow Ethernet cable to connect the

ETHERNET port to your network device, such as a switch.

4 Over ISDN: Use the included gray cable with a RJ-45

connector to connect the DSL port to another P-871M in CPE mode.

Over POTS: Use the included gray cable with a RJ-11 connector to connect the DSL port to another P-871M in CPE mode.

5 Use the included power adaptor to connect the POWER

socket to a proper power source.

6 Push the power switch to the on position.

1.2 CPE Mode

6 Push the power switch to the on position.

1.3 LEDs (Lights)

Look at the LEDs on the top panel of the P-871M.

•The POWER LED is on when the system is ready.

•The ETHERNET LED turns on if the ETHERNET port is con- nected to an Ethernet device and blinks when the P-871M is sending or receiving data through the ETHERNET port.

•The DSL LED is on if the VDSL connection between two P- 871Ms is set up.

•The CO LED is on when the P-871M is operating in CO mode.

VIf none of the LEDs (lights) are on, check your

connections. Make sure that you have the power adaptor connected to the P-871M and plugged in to an appropriate power source. Make sure the power source is turned on. Turn the P-871M off, wait for a few seconds and turn it back on. If the LEDs are still off, contact your vendor.

2 CLI Commands Configuration

When the P-871M is in CO mode, use the CLI (Command Line Interface) commands to configure it.

2.1 Syntax Conventions

This manual follows these general conventions:

• Units of measurement may denote the “metric” value or the “scientific” value. For example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000” or “1048576” and so on.

Command descriptions follow these conventions:

• Commands are in

• Required input values are in angle brackets <>; for example,

ping <ip-address> means that you must specify an IP

address for this command.

• Optional fields are in square brackets []; for instance vdsl profile [1|2], the name field is optional.

•The | (bar) symbol means “or”.

• italic terms represent user-defined input values; for example, in vdsl downrate [y], y can be replaced by the actual data rate that you want to set, for example, 10000.

• A key stroke is denoted by square brackets and uppercase text, for example, [ENTER] means the “Enter” or “Return” key on your keyboard.

courier new font.
