ABOUT THE PRODUCT 1

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 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.

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
