fl_fly_boy: do you even bother to read your own citations? Your
citation says that protection is only for metallic mode. You
therefore assume the only destructive surge is metallic? You do if
you don't have basic electrical knowledge. You do what propagandists
hope you will do? You only believe what was first told; then you do
everything to deny later and accurate facts. Propagandists hope more
people think that way. fl_fly_boy - the retail saleman who
recommended a secondary protectors was wrong. Spinning
Which component in the app note is the protection? Not the
Polyswitch as fl_fly_boy assumed. Read that post again. The
Polyswitch acts only like a fuse. The Sibar (or other equivalents
such as Sidactor) provides surge protection inside the phone AND for
only one type of surge. fl_fly_bly - where is the protection?
Already exists Inside the phone, modem, etc. as you were told
repeatedly. View the figure labeled "Figure 2: Modem Interface".
Protector is inside the modem. Protector is not a secondary (and
expensive) device. Protection is already inside the phone as I posted
and as fl_fly_boy repeatedly ignored.
Telephone appliance contains internal protection. Why would a
secondary protector do anything when a protector is already inside the
telephone? But then fl_fly_boy has no experience with POTS hardware
and no basic electrical knowledge. He did not know that protector
already exists even after reading his own application note.
fl_fly_boy has assumed the typically destructive transient is
metallic.

Other type of surges that are typically destructive are not
discussed because that protection is elsewhere.. Since the app note
only discussed metallic, then fl_fly_boy assumes only metallic
transients exist? Of course not. If he had basic knowledge, then
fl_fly_boy would not make those assumptions.
First, it should have been obvious to fl_fly_boy that the Polyswitch
does not provide surge protection. Obviously the SiBar is the
protector. Obviously the SiBar is only for one type of surge -
metallic. Most embarrassing is that fl_fly_boy still thinks
Polyswitch is for blocking surges. It is not. But explaining
anything more will only result in more denials in long rambling posts
and quotes that he does not understand.
Second, protection already exists inside telco equipment. Why would
spending big bucks for a secondary protector do anything when the
protector is already inside the phone? It would not. If fl_fly_boy
had learned this stuff or if he even read his app notes, then
fl_fly_boy would not have posted spin.
Third, what provides protection from another type of surge that
typically does damage? The telco 'whole house' protector ... if
properly earthed. Protector that makes all type of surges irrelevant
so that protection inside POTS equipment is not overwhelmed.
fl_fly_boy even demonstrated protection exists inside telephone
appliances. Now if he would only admit it. fl_fly_boy still insists
we must install on telephone cords what already exists inside the
telephone, modem, et al.
mm - for DSL modem protection - so that the protector circuits
already inside that DSL modem are not overwhelmed - you must inspect
and may need to upgrade your earthing system. The protector is only
as effective as its earth ground. The telco provided protector is
earthed so that protection already inside telephone and modem is not
overwhelmed.
