Getting to Know the P841C

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.

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.
