THE LINE UNIT

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.

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
