An example of this is where screw-type carbon block protectors — or other non
plug-compatible types — are in place and it is too costly to re-terminate the outside plant cable
on a 5-pin mounting block for only a few out-of-building terminals.

Installing the ITW Linx Enhanced Protector

The ITW Linx Enhanced Protector can be installed in series with existing primary protection.
The ITW Linx Enhanced Protector mounts directly on connecting blocks and requires a
separate ground bar.

Installing the 4C3S-75 Enhanced Protector

The 4C3S-75 protector cannot be installed in series with other types of primary protection. It
must be installed as the only protection on the line entering the building. For the 4C3S-75
protector there are a variety of 25-, 50-, and 100-pair protector panels equipped with 110-type
connecting blocks and/or RJ21X connectors.

equipment side of the protection in both buildings.
