In ringing mode (Ring relay in position 2), the only
protection device involved is the CLP200M.
In normal conditions, the CLP200M operates in re-
gion 1 of
A1
curve, and is idle.
If an overvoltage occuring between TIP (or RING)
and
GND
reaches
the
refe-rence (+/- 215V), the CLP200M acts and the
line is short-circuited to GND. At this time the oper-
ating point moves to region 2 for positive surges
(region 3 for negative surges). Once the surge cur-
rent disappears, the device returns to its initial
state (region 1).

overvoltage
For surges occuring between TIP and RING, the
CLP200M acts in the same way. This means that
the CLP200M ensures a tripolar protection.
When used alone, the CLP200M acts at the inter-
nal overvoltage reference level (+/- 215V). Fur-
