1.1.2 QFO-C Considerations
When installing QFO-Cs into the Total Access 3000/3010 shelf, the odd-numbered
slots of the shelf serve as the main slot and the even-numbered slots serve as the
auxiliary. If operating in a 1:1 protective mode, the slot that is adjacent and to right of
the main slot will then serve as the auxiliary slot. When operating in a non-protective
mode, the slot that is adjacent and to the right of the main slot must either remain
empty, or use an access module blank, P/N 1181953L1.
1.1.3 T1-OR, HTU-C, and H2TU-C Considerations
When installing either a T1-OR, HTU-C, or H2TU-C into the Total Access 3000/3010
shelf, the odd-numbered slots serve as the main slot and the even-numbered slots serve
as the auxiliary. If operating in a 1:1 protective mode, the slot that is adjacent and to
the right of the main slot will then serve as the auxiliary slot. When operating in a
non-protective mode, all 28/22 slots of Total Access 3000/3010 shelf can be used as
independent circuits.
NOTE
If 1:1 protection for the T1-OR, HTU-C, or H2TU-C is not desired, you can
use all 28/22 slots as independent circuits in the shelf. However, when a
QFO-C is used in a non-protection mode, then the slot adjacent and to the right
of the main slot is required to remain empty.
1.1.4 HD-10 (8 DSL mode) Considerations
Because the HD-10 is a double-wide module, it occupies the physical space of two
slots. There is no 1:1 protection feature available for this technology. The HD-10 is
capable of supporting ten U-interfaces. In this configuration, however, all four of the
bottom AMP connectors, labeled Pair 5-8, go to the DSX-1 cross connect, and Pair 5
in particular is unavailable to the HD-10 for DSL numbers 9 and 10, thus limiting the
HD-10 to 8 DSL mode.
