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.

1.3 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.

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.
