Boxes C and D
Boxes F and J
Boxes G and H
The criterion for box C is overcurrent protection that reduces currents above
1.3 A. This requirement is met by a 1 A fuse (a 1 A current fusing rating, not an
IEC 1 A current carrying rating).
Modems which pass FCC Part 68 Type B surges and non-operationally pass
Type A surges can use a fuse of 1 A or less, so the yes path to box D can be
followed. High performance modems which operationally pass both Type A
and B surges would need a fuse of greater than 1 A and so follow the no path
to box F.
The criterion for box D is a fire enclosure.
Few modems can afford fire enclosures. However, for an internal modem in a
known comp uter case, the case may be evaluated as a fire enclosure. A
successful case evaluation will give a yes and an equipment pass.
More likely, the modem w ill not have a fire enclosure. The no flow goes to box
H.
The criterion for box F is a pass to clause 6.3.3 requirements.
A yes goes to box G and a no goes to box J.
The criterion for box J is to pass Test 5.
If all the three pass criteria of Test 5 are met, this is a yes and the flow goes to
box G.
A no result fails the equipment.
The criterion for box G is a fire enclosure and spacings (See box D
comments).
A yes result passes the equipment and a no result leads to box H.
The criterion for box H is to pass Tests 2, 3 and 4. Test 2 is not required if
there is overcurrent protection that reduces currents above 1.3 A (See box C).
High performance mod ems, using fuses and without fire enclosures, must
pass tests 2, 3, possibly 3A if the fuse opens, and 4. For standard modems,
using fuses of 1 A or less and without fire enclosures, tests 3, 3A and 4 must
be passed.
If the two pass criteria of each of the tests performed are met, this is a yes
and the equipment passes.
A no result fails the equipment.
