DSX-1 "A" has transmit out of the system on connector eight, and receive into the
system on connector seven. DSX-1 "B" has transmit out of the system on connector
six, and receive into the system on connector five.
Cards using connectors 5 and 6 for local loops should not be mixed with cards using
these two connectors for their DSX-1 "B" interface. This is an issue solely with pre-
wiring the system. The system will operate with a mixture of these cards, but
connections in these two connectors will need to be routed to both local loop (MDF)
and DSX-1 wiring frames.

Fiber Loop Support

The system can accommodate as many as 28 fiber optic access modules, as well as two
fiber optic multiplexers. All fiber optic cable in Total Access 3000/3010 is routed out
the top front of cards installed in the system. This includes fiber optic cable used for
network interfaces as well as for delivering services across the local loop.
The heat baffle/fiber routing tray is recommended for routing fiber optic cables into
the system. This unit is installed above the associated system, and it can handle fiber
optic cables for a single system. Fiber optic cable is routed out of the top of a card into
the fiber tray, where it can be then routed out the sides or the back of the unit.
