4.4.1.1 Type A – 800V Surge (metallic) Terminal Connections
This surge waveform is intended to be applied between any
pair of connections on which lightning surges may occur,
including (for example):
a)
tip to ring;
b)
tip-1 to ring-1; and,
c)
for a 4-wire connection that uses simplex signaling, tip to
ring-1 and ring to tip-1.
The SGTEL-168 applies this surge between Terminals (A) and (B).
Therefore, the EUT lines to be tested should be connected to
these terminals for this surge, as shown in Figure 8.
