ABOUT THE PRODUCT
The ADC Campus-RS
™
(Rate-Selectable) Fractional Interface Card provides
a connection between a High-bit-rate Digital Subscriber Line (HDSL) and a
network or other digital equipment. It installs into either a:
• Campus-Star chassis, along with a Campus-RS Line Unit
• Campus-RS Desktop Unit
This equipment comprises half of a High-bit-rate Digital Subscriber Line
(HDSL) transmission system. When connected to another Campus-RS,
Campus-T1
®
, Campus-768
®
, or Campus-E1
®
Desktop Unit or Line Unit, the
Campus-RS system can transport digitized voice, data, and video signals over
existing copper wire at a number of different HDSL rates.
The Campus-RS Fractional Interface Card converts incoming data, control
signals, and timing information into its internal format. The desktop unit or
line unit then converts this format to a Two Bit, One Quaternary (2B1Q)
HDSL line format for high-speed transmission over a local telephone-grade
copper network.
