of network 70 a jumper not shown but similar to jumper 41 in fig4 is connected to a connector 32 c in network outlet 31 c the previous discussion regarding the splitting of the signal spectrum also applies here and allows for data transport between dte units 24 a and 24 b via the high frequency portion of the spectrum across segments 15 c and 15 d when only jumper 41 is connected at network outlet 31 c the same point to point performance as previously discussed can be expected the only influence on communication performance is from the addition of segment 15 d which extends the length of the media and hence leads to increased signal attenuation some degradation however can also be expected when a telephone is connected to jumper 41 at network outlet 31 c such degradation can be the result of noise produced by the telephone in the high frequency data communication band as well as the result the addition of a tap caused by the telephone connection which usually has a non matched termination those problems can be overcome by installing a low pass filter in the telephone in a preferred embodiment of network 70 a splitter 50 b is installed in network outlet 31 c splitter 50 b provides the lpf functionality and allows for connecting a telephone via connector 53 b however in order to allow for continuity in data communication there must be a connection between the circuits in connectors 56 b and 57 b such a connection is obtained by a jumper 71 as shown in fig7 installation of splitter 50 b and jumper 71 provides.
