ABOUT THEPRODUCT1

The Campus-RS (Rate Selectable) Line Unit, mated with an RS interface card in aCampus-Starchassis, comprises half of aHigh-bit-rateDigital Subscriber Line (HDSL) transmission system. When connected to another Line Unit installed in aCampus-Star® chassis or to aCampus-RSDesktop 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-RSsystem is compatible, over the HDSL link, with earlier versions of Campus products. You can connect theCampus-RSLine Unit, through the HDSL link, to aCampus-E1®,Campus-T1®,orCampus-768® Desktop Unit or Line Unit. TheCampus-RSsystem is not compatible withCampus-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-RSstandard HDSL Operating Mode supports three preset transmission rates:

2.048 Mbps (E1)

1.544 Mbps (T1)

768 kbps

About the Product

When connecting to another Campus-RSunit, 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-loopconnection, the Line Unit supports rates from 64 kbps to 2304 kbps in 64 kbps increments, depending on the interface card.

Over a dual-loopconnection, the Line Unit supports rates from 256 kbps to 4608 kbps in 128 kbps increments, depending on the interface card.

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-1Interface Card only supports the T1 standard rate. The User Manual for the Interface Card provides a list of rates supported by the 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-offsbetween 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.

About the Product

HDSL REACH ANDTRANSMISSIONRATE

Four factors determine the maximum transmission rate and loop length of the HDSL line:

the wire gauge of the line

the condition of the line (presence of bridge taps, splices, and so on)

whether the line uses one or two loops

the amount of noise on the line

The following charts show the maximum loop length over the range of HDSL transmission rates for 26 AWG (.40 mm), 24 AWG (.51 mm), 22 AWG (.61 mm), and 19 AWG (.91 mm), respectively. The shaded area on each chart shows a range of expected maximum loop lengths that will provide a bit error rate (BER) of greater than 5E-8:

The best case (longest reach) is measured in a noiseless environment.

The worst case is measured using an industry-standardnoise model that simulates the cable pair in a bundle with 49 other cable pairs each transmitting with similar frequency characteristics.

The actual reach will fall somewhere between these two cases, and will vary according to such factors as the condition of the loop pairs, the presence of bridge taps, splices, line noise, and so on.

Depending upon the desired data rate and wire gauge, two-loopoperation provides between 12% and 47% greater reach than one loop operation at the same data rate. For example, for a 24 AWG loop, a unit configured fortwo-loopoperation at 1152 kbps will have a maximum reach of approximately 4.6 miles, whereas aone-loopconfiguration at 1152 kbps will have a maximum reach of approximately 3.0 miles.
