Coral IPx 800 Installation Manual
Generally, leased or switched circuit facilities provided by the local telephone utility
company are equipped with primary protection devices installed with the circuit.
However, privately owned aerial or buried cable feeding from one building to another
may not be equipped with protection devices. Always consult with whomever
provided the circuits to determine whether protection devices are present, and if so,
what type. Never assume that protection devices have been provided by another party,
or that existing protection devices are adequate.
The secondary protection has to include a leakage current protector in series of every
wire, tip and ring, on every port that is either connected to the public telephone
network or to an out of the building cable. The requirement is in accordance with UL
Specification 60950, Third Edition or CSA C22.2 No. 60950. The required protectors can
be mounted directly on a 66 block in the MDF.
