When connecting to another Campus-RS desktop unit or line unit, Standard Mode is still supported, providing access to HDSL transmission rates of T1, E1 and 768 kbps. In addition, the Campus-RS system can be configured to support an extended set of HDSL transmission rates, over either one or two HDSL loops.

To support these additional transmission rates, set the following options on the Campus-REX2:

•Set the HDSL Operating Mode to Extended Mode.

•Set the Extended Mode Loop Configuration to 1 Loop or 2 Loops, depending on the physical layout of your HDSL network.

•Set the Extended Mode HDSL Rate to the required setting.

The range of rates available for the HDSL Rate depends on the setting of the Extended Mode Loop Configuration:

–1 Loop HDSL rate settings are between 128 kbps and 1.152 Mbps, in 64 kbps increments.

–2 Loop HDSL rate settings are between 256 kbps and 2.304 Mbps, in 128 kbps increments.

Not all of these modes and rates are available if the remote Campus-RS system does not support them. Refer to the remote interface card User Manual to see the HDSL modes and rates supported by the card.

For information on setting these options, see “Selecting HDSL Parameters” on page 21.
