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. 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. 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 Installing and Configuring the Line 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 line Campus-RS UnitHDSL jack 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.

Use the guide rails to align the card. 4 When the Line Unit is in as far as possible, push the retaining latch in until it snaps into place. Assuming the Campus-Star power is on, the Line Unit performs a power-on test. After completing the test, the HDSL LED flashes red. COMPLETE SYSTEM INSTALLATION To complete the installation of the Campus-RS system and ready it for use: 1 Install the remote unit. This may be an interface card installed in a Campus Desktop Unit or an interface card and line unit installed in another Campus-Star chassis. 2 Connect the cables according to the instructions in the Campus-Star or Campus-RS Desktop Unit documentation. Campus-RS Line Unit User Manual May 29, 2002 Installing and Configuring the Line Unit DETERMINE THE HDSL OPERATING MODE The Campus-RS Line Unit supports two operating modes: • Standard Mode provides HDSL compatibility with earlier versions of Campus products, such as the Campus-T1 Desktop Unit. • Extended Mode provides a wide range of HDSL transmission rates when the Line Unit is connected to another Campus-RS product. The following illustration shows the operating modes available for the possible Campus system configurations. Standard Mode Campus-RS Two pairs Legacy Campus-T1/E1 Campus-RS One pair Standard Mode Legacy Campus-768 * Standard Mode or Extended Mode Campus-RS One or two pairs Campus-RS * Depends on: Interface card capabilities, available/desired number of pairs, reach requirements.
