ROTECTION
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.
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
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.
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.
