Consideration should be given to installing secondary protection on each
out-of-building facility connected to the TAE if any of the following conditions
e x i s t :
The service entrance (protector block) ground is not properly
installed (bonded to building ground, for example).
The local telephone company does not permit access to the
protector block.
High-voltage surge protection is not provided.
Install the CBC as follows:
1. Connect one end of the CBC to the ground point at the network
i n t e r f a c e .
2. Wrap the CBC loosely around the cable from the network interface
to the TAE and then around a splitter cable to the cabinet. If
possible, tie wrap the CBC to the cables.
