P841C Central-Side VDSL Modem
Getting to Know the P841C 1-1
This chapter describes the key features, benefits and applications of your P841C.
The P841C is a VDSL Line Termination (LT) modem that is the perfect partner for the P841 VDSL subscriber
modem. It maps traffic from one VDSL (Very high bit rate Digital Subscriber Line) subscriber to one 10/100M
Ethernet that connects to a computer or LAN switch. It has built-in POTS/ISDN splitters and a console port for
local management.
1.1 Features
Compact Design With Integrated Splitters
The P841C is just 18cm x 12.6cm x 3cm (Width, Depth, Height) in size. Because of built-in POTS/ISDN splitters,
you do not have to allocate extra space for external splitters that separate voice-band and DSL signals.
10/100 Mbps Fast Ethernet Port
The 10/100 Mbps Fast Ethernet port allows you to connect it to a LAN switch.
VDSL Modes and Rates
The P841C supports the following DSLAM VDSL modes.
• 10BaseS mode giving upstream rates from 1.56 Mbps to 18.75 Mbps and downstream rates of 4.17
Mbps Kbps to 16.67 Mbps.
• ANSI Mode giving upstream rates from 1.56 Mbps to 6.25 Mbps and downstream rates of 4.17 Mbps
to 16.67 Mbps.
• ETSI Mode giving upstream rates from 1.56 Mbps to 6.25 Mbps and downstream rates of 4.17 Mbps
to 12.50Mbps.

1.2 Application Example
The following diagram depicts a typical application of the P841C VDSL line termination modem working
together with the P841 VDSL subscriber modem in a campus setting. With the built-in splitters, VDSL service
can coexist with voice service on the same line.
