ABOUT THE PRODUCT 1 The Campus-RS (Rate Selectable) Desktop Unit, with an RS interface card installed, comprises half of a High-bit-rate Digital Subscriber Line (HDSL) transmission system. When connected to another Desktop Unit or to a Line Unit installed in a Campus-RS chassis, the Desktop Unit can transport digitized voice, data, and video signals over existing copper wire at a number of different HDSL transmission rates.
About the Product When connecting to another Campus-RS Desktop Unit or Campus-RS Line Unit, the three standard HDSL transmission rates are available. In addition, the Desktop Unit can be configured to support an extended HDSL Operating Mode, as follows: • Over a single-loop connection, the Desktop Unit supports rates from 64 kbps to 2304 kbps in 64 kbps increments, depending on the interface card.

About the Product HDSL REACH AND TRANSMISSION RATE There are four components that 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 on page 1-6 through page 1-7 show the maximum loop length over the range of HDSL transmission rates for 26 AWG (.40 mm), 24 AWG (.51 mm), 22 AWG (.

SETTING UP AND TESTING THE DESKTOP UNIT 2 This chapter describes how to install an interface card into the Campus-RS Desktop Unit, set basic configuration options, and test the HDSL link. Make sure the interface card you are installing is a Campus-RS interface card. The Campus-RS Desktop Unit is not compatible with previous versions of Campus interface cards.
Setting Up and Testing the Desktop Unit Install the NID on the HDSL line between the HDSL jack and the Telephone Company (Telco) demarcation point. Telco demarcation point HDSL line port NID HDSL jack Campus-RS Unit HDSL line 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.
Setting Up and Testing the Desktop Unit INSTALLING AN INTERFACE CARD You can install any ADC Campus-RS interface card into the Campus-RS Desktop Unit. To install the interface card: 1 Slide the card into the guide rails in the rear of the Desktop Unit.

Setting Up and Testing the Desktop Unit • Extended Mode provides a wide range of HDSL transmission rates when the Desktop Unit is connected to another Campus-RS product. The following illustration shows the operating modes available for the possible Campus system configurations.
Setting Up and Testing the Desktop Unit SET THE HDSL OPERATING MODE AND TRANSMISSION RATE This section provides basic instruction for setting the HDSL Operating Mode and transmission rate. The actual steps depend on the interface card in the Desktop Unit. Refer to the interface card user manual for a description of configuration and implementation options.
Setting Up and Testing the Desktop Unit Standard Mode Configuration This section continues from Step 5 in the previous section to set a standard HDSL transmission rate. 1 If the Operating Mode is set to STANDARD, proceed to Step 3. Otherwise, press Enter. 2 Press Next until STANDARD displays, then press Enter. The LCD displays OPERATING MODE. 3 Press Next until HDSL RATE displays, then press Enter. 4 Press Next until the desired HDSL transmission rate displays, then press Enter.
Setting Up and Testing the Desktop Unit 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.
Setting Up and Testing the Desktop Unit It is recommended that the Transceiver Mode be set as follows to avoid any link startup or operation problems: • 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.
Setting Up and Testing the Desktop Unit TEST THE HDSL PORT It is recommended that you test all Desktop Units at your location prior to installing units at a remote site. This minimizes additional trips to the remote site to troubleshoot problems. It is also possible to test a Desktop Unit with a Line Unit installed in a Campus-Star chassis. This requires creating a cable to connect the HDSL port on the Desktop Unit to the port on the Campus-Star.

The units attempt to synchronize the HDSL link. Synchronization may take up to 60 seconds or several minutes, depending on the interface card.
Setting Up and Testing the Desktop Unit TEST THE DATA PORT The data port of most Campus interface cards can be tested prior to installing the Desktop Unit in a remote location. This minimizes the chance of having to make additional trips to the remote site to troubleshoot problems. To test the data port, initiate a loopback from the local data port toward the local data port. Refer to the interface card user manual for instructions on initiating loopbacks.

DEPLOYING THE DESKTOP UNIT 3 This chapter describes how to deploy the Desktop Unit into its operating location. SET UP THE HDSL LINE Before you can connect the Campus-RS Desktop Unit to the HDSL line, you must first connect and install the RJ-45 modular jack that came with the Desktop Unit. You need needle-nosed pliers and a No. 2 standard screwdriver to complete these steps. You can connect the Desktop Unit to two different types of HDSL lines: • Dual-Loop uses two pairs of copper wire.
Deploying the Desktop Unit Dual-Loop Line A dual-loop line requires two pairs of wire. Use the same wiring for both the local and remote sites. A dual-loop line is compatible with all the standard modes and extended modes supported by the interface card. 3-2 1 Separate the two halves of the RJ-45 modular jack. 2 Connect the Tip wire for HDSL loop 1 to pin 1 of the jack. 3 Connect the Ring wire for HDSL loop 1 to pin 2 of the jack. 4 Connect the Ring wire for HDSL loop 2 to pin 4 of the jack.
Deploying the Desktop Unit Single-Loop Line A single-loop line requires a single pair of wire. Use the same wiring for both the local and remote sites.
Deploying the Desktop Unit CONNECT THE DESKTOP UNIT TO THE HDSL LINE To finish setting up and connecting to the HDSL line: 1 Place the RJ-45 jack where you are going to install it and push the excess wire into the punch box. 2 Use the two provided screws to screw the jack to the wall. 3 Snap the jack cover into place.
