ADTRAN Total Access 3000 System Manual page 79

Thus, every access module slot in the system can access up to a maximum of four
DSX-1 network interfaces, but any access module that uses all four of its available
DSX-1 network interfaces (e.g., QFO-C) precludes active use of any DSX-1 network
interfaces in the paired slot. Thus, when an access module using all four available
DSX-1 network interfaces is installed, the paired slot is restricted to being a redundant
card backing up the active module in the other paired slot. Or it can be an access
module that derives its network interface from a multiplexer installed in one of the
multiplexer slots of this same system. The sum of active DSX-1 network interfaces
available in two paired slots is a maximum of four. The system supports a total of (4
DSX-1 network interfaces per pair of access module slots) x (14 slot pairs), or 56
DSX-1 network interfaces.
To support pre-wiring, access modules using the "B" DSX-1 network interface
(e.g., QFO-C) should not be mixed in the same system with access modules
requiring the use of connectors 5 and/or 6 (e.g., HD10) for local loop
connections. This requires pre-wiring the same AMP Champ connector to two
different frames when a system is first installed. Nothing prevents the system
from operating with a mix of DSX-1 and local loop connections in connectors
5 and 6. The issue is solely one of pre-wiring. For further information on
wiring for different technologies, refer to the Application Guidelines section
of the manual.
