Campus-REX2 RS Interface Card User Manual 137
Compatibility with Campus-RS Products
The Campus-REX2 RS Interface Card is also compatible, over the HDSL
link, with another Campus-RS unit, as shown in the following illustration.
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.
For information on setting these options, see “Selecting HDSL Parameters”
on page 21.
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.
