Leaving any ports punched down but not connected to a telephone, may
result in erratic operation.
Correct Installation process
It is important to connect a telephone to every jack that is connected to
the system. Extensions connected to a cable with “Bridge Taps”, may
experience distortion. If locating a bridge tap is not practical, a quick
resolution is to use a different cable pair such as the Yellow/Black or
White/Orange.
Note:
There should not be any unconnected telephones at the end of a
cable run that is over 200 feet.
Endpoint Device
Every live telephone jack connected to the system will receive a data signal. If
the system finds an open jack (bridge tap) the data signal may be lost, causing
the remaining digital telephone endpoints to receive erroneous data, which may
lead to improper operation. Therefore, for proper operation each live telephone
jack at the end of a cable run, connected to the system, must have either a
digital telephone endpoint or an endpoint device. Symptoms of an open jack
include – but not limited to - voice distortion, static and slow speakerphone
reaction when the button is pressed, problems accessing CO Lines, etc.
