Testing a loopback jack without a smart jack
When the loopback jack is added to a span that does not contain a smart jack, the span is
divided into 2 sections: from the MM710 to the loopback jack and from the loopback jack to the
central office (CO). Section 2 includes the short cable from the loopback jack to the dumb block
demarcation point (part of the loopback jack). This cable is the only part of Section 2 that is part
of customer premises wiring. It is not covered in the loopback jack’s loopback path. See
Figure 40: Network interface at “dumb” block for an MM710 multi-media module
