PRACTICE 
5. DESIGN CONSIDERATIONS
FOREIGN AND SURGE
VOLTAGE PROTECTION
5.01 When telephone lines connected to the line circuit are exposed to
foreign voltages by direct contact or induction (e.g., power line crosses
or lightning), protection devices must be installed on the customer’s
premises. These devices must be capable of providing a path to ground
from tip to ring for foreign 
 that exceed 600 V peak.
OVERLOAD LEVEL
5.02 Signal levels exceeding 
 
 applied to the tip and ring will
cause distortion in the system.
