RE: FCC 68 surge for Bri -Reply

[Bill Vonalven]

Jack, the A surge is the standard surge. No failure mode causing harm to
network. Equipment does not have to work afterwards; whereas, the
Type B surge contains about half the energy of the Type A - also no
failure modes causing harm to network; but equipment must be
operational afterwards. A lot of people are insuring their designs are
opererational after the A surge; it cuts down substantiallly oin fleid
returns. In that case we call it the S surge.
