ABOUT THE PRODUCT

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
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
Desktop Unit or Line Unit. The Campus-RS system is not compatible with

Campus-384

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:

®

Desktop Units or Line Units.

®

chassis or to a Campus-RS Desktop

®

, Campus-T1®, or Campus-768®

• 2.048 Mbps (E1)

• 1.544 Mbps (T1)

• 768 kbps

Campus-RS Line Unit User Manual 1

About the Product

When connecting to another Campus-RS unit, 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-loop connection, the Line Unit supports rates from 64 kbps

to 2304 kbps in 64 kbps increments, depending on the interface card.

• Over a dual-loop connection, 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-1 Interface 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-offs between 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 AND TRANSMISSION RATE

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

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

• The worst case is measured using an industry-standard noise model that

simulates the cable pair in a bundle with 49 other cable pairs each
transmitting with similar frequency characteristics.

-8

:

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-loop operation 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 for two-loop
operation at 1152 kbps will have a maximum reach of
approximately 4.6 miles, whereas a one-loop configuration
at 1152 kbps will have a maximum reach of approximately

3.0 miles.

INSTALLING AND

CONFIGURING

THE

This chapter describes how to install the Campus-RS Line Unit and its
corresponding interface card into a Campus-Star, and how to set up the HDSL
link.

Make sure the interface card you mate with the Line Unit is
a Campus-RS interface card. The Campus-RS Line Unit is not
compatible with previous versions of Campus interface
cards.

LINE UNIT

SURGE PROTECTION

To protect you and your Campus-RS devices, ADC recommends the use of a
dual line Network Interface Device (NID) with a gas tube or solid state
composition. The NID can protect both Campus-Star chassis and Campus-RS
Desktop Units.

Most lines leased from your local telephone company already
have protection devices installed. Contact your telephone
company to see if your lines require additional protection.

2

For surge protection:

• the maximum recommended breakdown voltage should not exceed

300 Vdc

• carbon based protection devices are not recommended

• data line surge protectors can also be used

Campus-RS Line Unit User Manual 9

Installing and Configuring the Line Unit

Install the NID on the HDSL line between the HDSL jack and the Telephone
Company (Telco) demarcation point.

ADC also suggests providing power line protection for critical circuits in high
lightning areas. Use conditioned AC voltage, furnished through an
Uninterruptible Power Supply (UPS), that is bonded to a good facilities
ground. This provides additional protection against voltage transients
entering through the power lines.

INSTALL THE LINE UNIT

To install the Line Unit:
1 Install the interface card into the back of the Campus-Star chassis,

following the instructions in the User Manual for the card.

Make sure you install the interface card before the line unit.
Installing the card with the line unit already installed may
cause damage to the card, the line unit, or both.

2 Ensure that the retaining latch is pulled completely forward and down.

SET THE HDSL TRANSCEIVER MODE

The Transceiver Mode option determines the hierarchy of the two Campus
units when attempting to establish an HDSL link. There are three settings:

• If a unit is set to Master, it initiates the HDSL link. The other Campus

unit must be set to Slave or Auto.

• If a unit is set to Slave, it waits for the other Campus unit to initiate the

HDSL link. The other unit must be set to Master or Auto.

• If a unit is set to Auto, it automatically switches between Master and

Slave until an HDSL link is established. The setting of the other Campus
unit is irrelevant. This is the default setting.

The default setting of Auto Mode is the recommended setting, regardless of
the setting of the remote unit. To determine the current Transceiver Mode, or
to change the setting:

1 Press Escape four times to go to the top level menu.
2 Press Next until HDSL LINK CONFIG & STATUS displays.
3 Press Enter. OPERATING MODE displays.

Installing and Configuring the Line Unit

OPERATING WITH EARLIER VERSIONS OF

AMPUS PRODUCTS

C

Campus-RS Desktop and Line Units are fully compatible with most of the
earlier versions of Campus products, including Campus-E1, Campus-T1, and
Campus-768. The Campus-RS Desktop and Line Units are not currently
compatible with Campus-384 products.

Furthermore, if a Campus-RS unit is connected over an HDSL link to an
earlier Campus product, and if either unit has the HDSL Transceiver (XCVR)
Mode set to AUTO, the HDSL link may not operate properly.

When operating the Campus-RS product with an earlier version of the
Campus products, to avoid any problems with link startup or operation, it is
recommended that the Transceiver Mode be set as follows:

• Campus-RS = MASTER

• Campus E1/T1/768 = SLAVE

If one or both units are already set to AUTO and the HDSL link is active,
disconnect the HDSL link, change the settings as recommended, and
reconnect the link. This will assure the link integrity on any subsequent
startups.

This situation does not apply to a circuit with two Campus-RS
units. You may leave the units set to their default setting of
AUTO, and they will operate properly.
