S8100 Installation and Upgrades
November 2003
When possible, every new and reused wiring installation should use blocks that accept the standard 5-pin
plug-in 4C3S-75 protector. However, this may not be cost-effective in some cases; for these installations,
the ITW Linx protector may be installed. For example, if screw-type carbon block protectors (or other
comparable plug-incompatible types) are in place, it may be too costly to re-terminate the outside cable
on a 5-pin mounting block for only a few out-of-building terminals.

The ITW Linx Enhanced Protector may be installed in series with existing primary protection. Note the
4C3S-75 protector cannot be installed in series with other types of primary protection, but must be
installed as the only protection on the line entering the building. For the 4C3S-75 protector, various 25-,
50-, and 100-pair protector panels are equipped with 110-type connecting blocks and/or RJ21X
connectors. The ITW Linx Enhanced Protector mounts directly on connecting blocks and requires a
separate ground bar.

The maximum range for out-of-building digital voice terminals is:
•
3400 feet (1036 m) when using 24-AWG (0.26-mm
2
) wire
•
2200 feet (670 m) when using 26-AWG (0.14-mm
2
) wire
With the use of a data-link protector (an isolating transformer used to remove phantom power on the
system side and re-introduce it on the terminal side), the range can extend to
system side and re-introduce it on the terminal side), the range can extend to
•
5000 feet (1524 m) using 24-AWG (0.26-mm
2
) wire
•
4000 feet (1219 m) using 26-AWG (0.14-mm
2
) wire
When using a protector, the voice terminal must be locally powered by an external power supply or
through the AC power cord provided with some of the 7400-series voice terminals. Install the protector
on the equipment side of the protection in both buildings.
