Installing the S8700 IP Connect
May 2002
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.
Installing the Data Link Protector
The maximum range for out-of-building digital telephones is 3400 feet when using 24 AWG
(#5) (0.5 mm
2
) wire and 2200 feet (670 m) when using 26 AWG (#4) (0.4 mm
2
) wire. The
range can be extended to 5000 feet (1524 m) using 24 AWG (#5) (0.5 mm
2
) wire or 4000 feet
(1220 m) using 26 AWG (#4) (0.4 mm
2
) wire with the use of a data link protector. The protector
is an isolating transformer used to remove phantom power on the media gateway side and
re-introduce it on the terminal side.
When a protector is used, the telephone must be locally powered by an external power supply or
through the AC power cord provided with some telephones. The protector is installed on the
equipment side of the protection in both buildings.
