About the Product
2 May 29, 2002 Campus-RS Line Unit User Manual
When connecting to another Campus-RS unit, the three standard HDSL
transmission rates are available. In addition, the Campus system can be
configured to support an extended HDSL Operating Mode, as follows:
• Over a single-loop connection, the Line Unit supports rates from 64 kbps
to 2304 kbps in 64 kbps increments, depending on the interface card.
• Over a dual-loop connection, the Line Unit supports rates from 256 kbps
to 4608 kbps in 128 kbps increments, depending on the interface card.
The transmission rate you select depends on the type of copper infrastructure
and the physical layout of the network. The extended HDSL Operating
Modes provide a way to make trade-offs between the reach of the HDSL line
and the transmission rate.
The default setting for the HDSL Operating Mode depends upon the interface
card. If necessary, change the HDSL Operating Mode and associated
parameters through the system configuration menus. Instructions for using
the menus are in the User Manual for the interface card mated with the
Line Unit.
While the Line Unit supports all the rates listed above, the
actual rates available depends on the interface card installed
in the Line Unit. For example, the Campus Fractional Interface
Card support the full range of transmission rates, while the
CSU/DSX-1 Interface Card only supports the T1 standard rate.
The User Manual for the Interface Card provides a list of rates
supported by the card.
