3.4.1. Ringing mode
The figures 23 and 25 give the voltage and current at the CLP270M terminals in Ringing mode and Speech
mode. The CLP270M is able to withstand all the first level AC power fault tests as required in the table 4-7
of GR-1089-CORE standard.
For the second level AC power fault tests serial protection as PTC or fuse are needed.
All these curves, lightning and AC power fault represent the behavior of the CLP270M in worst case tests,
any how the CLP270M withstands all the others surges of the Bellcore GR1098 standard. For the second
level AC power fault test, the use of series protection elements (PTC or fuses) are needed.
