See Figure 9 for the pinout of a local loop connector on the system backplane (all
eight share identical pinouts). Note that Pin 64 is provided for automatically grounding
the shield of an installed cable. Recommended part number for cables provided by
TS1 (see Application Guides in this manual) are designed so that pin 64 is connected
to the cable shield drain wire.

Connectors 7 and 8 (labeled Pair 7 and 8 and located at P9 and P10, respectively)
deliver DSX-1 "A" to each access module slot in the system. Connectors 5 and 6
(labeled Pair 5 and 6 and located at P6 and P7, respectively) deliver DSX-1 "B" to
each access module slot in the system. Regardless of what is installed in the
multiplexer slots, the DSX-1 network interfaces are always available for use by an
access module installed in an access module slot.
Pairs 5 and 6 will be used for DSX-1 (DSX-B) if the user installs a dual DSX-1 card,
such as a QFO-C, in Total Access 3000/3010. If no dual DSX-1 cards are installed,
then pairs 5 and 6 can connect to the MDF.
Access modules are grouped into pairs consisting of an odd-numbered slot and an
even-numbered slot immediately to the right. For delivering DS2 services, a single slot
access module has access to both DSX-1 network interfaces dedicated to its slot, as
well as the two DSX-1 network interfaces dedicated to its paired slot.
