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.
Features
- Uses a multi-stage hybrid circuit for the best possible protection
- Handles surge energy up to 1.5 kW Conforms to the UL497A telco specification (except E1 versions)
- Available for ISDN-U (8-wire), ISDN-ST (4-wire), T1, E1, ISDN PRI, DDS, leased line and dial up configurations
- Diverts surges directly to chassis ground through braided metal ground strap Equipped with two RJ-45 jacks or four BNC connectors
- Easy to install Made in the U.S.A.
- Nine versions custom-tailored to specific telco interfaces
- Surge handling capacity of 1500 Watts
- Surge handling capacity of 600 Watts for G.SHDSL (2W/4W)
- Surge energy diverted to ground through braided metal strap
- "Fail Safe" design protects ISDN equipment in case of overload 6 in. (15.24 cm) modular cable included
