Overview
Your telco lines are a vital data link with the outside world. But they can also end up bringing some very undesirable transient spikes into your data ports. The Patton Model 552 installs between an incoming telco line and dial-up/leased line/xDSL modem, ISDN modem (a.k.a. TA or NTU), T1/E1/PRI or DDS and intercepts harmful telco line transients before they cause hardware damage. Surge energy is then diverted to nearby chassis ground through a braided metal strap.

The following versions are available:
  • Model 552-D2 (dial-up line) protects RJ-11 pins 3 & 4
  • Model 552-D4 (dual dial-up line) protects RJ-11 pins 2, 3, 4 & 5
  • Model 552-DDS protects RJ-45 pins 1, 2, 7 & 8
  • Model 552-T1 (T1, E1, PRI) protects RJ-45 pins 1, 2, 4 & 5
  • Model 552/U protects pins 3, 4, 5 & 6 on the RJ-45 connector
  • Model 552-ST (ISDN) protects all 8 RJ-45 pins. The ISDN versions of the Model 552 protect both data and battery signals.
  • Model 552-GS2 protects RJ-45 pins 4 & 5, whereas the 552-GS4 protects RJ-45 pins 3,4,5 & 6.
The G.SHDSL versions of the Model 552 have a surge handling capacity of 600W, all other versions can handle surges of 1500 Watts. A 6-inch (15-cm) adapter cable is supplied with all Model 552 versions.
