The Campus-RS ™ (Rate Selectable) Line Unit, mated with an RS interface
card in a Campus-Star chassis, comprises half of a High-bit-rate Digital
Subscriber Line (HDSL) transmission system. When connected to another
Line Unit installed in a Campus-Star
® chassis or to a Campus-RS Desktop
Unit, the Line Unit can transport digitized voice, data, and video signals over
existing copper wire at a number of different HDSL transmission rates.
The Campus-RS system is compatible, over the HDSL link, with earlier
versions of Campus products. You can connect the Campus-RS Line Unit,
through the HDSL link, to a Campus-E1
® , Campus-T1 ® , or Campus-768 ®
Desktop Unit or Line Unit. The Campus-RS system is not compatible with
Campus-384
® Desktop Units or Line Units.
All earlier versions of Campus products are manufactured to operate at a
single HDSL transmission rate. To establish an HDSL link with an earlier
product, the Campus-RS standard HDSL Operating Mode supports three
preset transmission rates:
• 2.048 Mbps (E1)
• 1.544 Mbps (T1)
• 768 kbps
The interface card mated to the Line Unit determines the
HDSL transmission rates available. Some cards may support
fewer rates or only one rate. See the manual for the interface
card to determine the available HDSL transmission rates for
the system.
