2.2 DESCRIPTION
The potential threats to ISDN and Telco hardware are vast:
lightning, AC power induction, electrostatic discharge, ground potential
differences, EMI/RFI interference and more. The Patton Model 552 has
been designed to greatly reduce these risks. Just attach one unit to
each of your telco ports and rest easy.
The Model 552 connects directly between twisted pair telco cables
and their respective I/O ports. Grounding is accomplished using an
external ground strap that provides a separate unit-ground to chassis-
ground connection. By shunting threatening voltages directly to chassis
ground, the Model 552 insures data integrity and protects connected
equipment from damage.
The Model 552 uses a solid state design and sophisticated
multistage hybrid circuits to achieve maximum protection without
performance loss. Eight versions are available: Model 552-ST, 552-
D8, and 552-L8 protect all 8 pins; Model 552-D6 protects six pins;
Models 552-DDS, 552-D4, 552-U, 552-L4, 552-E1, 552-E1 CX, and
552-T1 protect four pins; and, Model 552-D2 protects two pins. All
versions provide up to 1500 Watts of data line protection.
NOTE: Model 552-L8 may be used to protect Leased Line, DDS,
T1, E1, ISDN PRI, and ISDN BRI “U” and “ST” interfaces.
WARNING!: This product will not provide complete protection
should your equipment or building be subject to a direct lightning hit.
