DRIVE UNIT
Function
This option enables remote monitoring, isolation, and
reduction of ingress on the return path by providing
signal attenuation of 6 dB or cutoff of 38 dB typical. The
unit is shipped with a jumper in this location.
These options should be installed in place of the JMP
jumper to activate the third output of the MB*/*.
This optional board provides additional flatness
response correction in the return path for systems that
must meet especially stringent return-path flatness
requirements.
This housing accommodates the signal bypass jumper,
which prevents transmission loss to subscribers during
maintenance and upgrades.
