Overview
CPE is defined as any telephone terminal equipment which resides at the customers
site and is connected to the public switched telephone network (PSTN). Telephones,
modems, caller ID adjunct boxes, PBX
’
s and answering machines are all considered
CPE.
Protection Requirements
CPE should be protected against over-voltages that can exceed 800V and surge
currents up to 100A. In Figures 3-1 through 3-5, the SIDACtor was chosen because
the associated peak pulse current (I
PP
) is great enough to withstand the lightning
immunity test of FCC Part 68 without the additional use of series line impedance.
Likewise, the fuse in Figures 3-1 through 3-5 was chosen because the amps
2
time (I
2
t)
rating is large enough to withstand the lightning immunity tests of FCC Part 68, but
small enough to pass UL power cross conditions.
Applicable Regulatory Requirements
FCC Part 68
UL 1459
UL 1950
All CPE that is intended for connection to the PSTN must be registered in compliance
with FCC Part 68. Also, because the National Electric Code mandates that
“
equipment
intended for connection to the telephone network be listed for that purpose
”
,
consideration should be given to certifying equipment with an approved safety lab
such as Underwriters Laboratories.
CPE Reference Circuits
Figures 3-1 through 3-5 are examples of interface circuits which meet all applicable
regulatory requirements for CPE. The P3100SB and P3100EB are used in these
circuits because the peak off-state voltage (V
DRM
) is greater than the potential of a
Type B ringer superimposed on a POTS (plain old telephone service) battery.

It should be noted that the circuits shown in Figures 3-1 through 3-5 provide an
operational solution for FCC Part 68, however FCC Part 68 allows CPE designs to
pass non-operationally as well.
For a non-operational solution, the I
PP
rating of the SIDACtor and the I
2
t rating of the
fuse should be coordinated such that both will withstand the Type B surge, but during
the Type A surge, the fuse will open (Table 5-1, Fuse Selection Criteria).
Note: For alternative line interface protection circuits, please refer to Regulatory Requirements
and Regulatory Compliant Solutions.
