1.1.2 HTU-C, H2TU-C, and T1-OR Considerations
When installing either HTU-Cs, H2TU-Cs, or T1-ORs into Total Access 3000/3010,
the odd-numbered slots of the shelf serve as the main slot and the even-numbered slots
serve as auxiliary. Therefore, the main module is always placed in the odd-numbered
slots and the auxiliary module should be placed to the immediate right.
NOTE
28/22 T1-ORs, 28/22 HTU-Cs, and 28/22 H2TU-Cs can be used as
independent circuits if 1:1 protection feature is not desired.
1.1.3 HD-10 (8 or 10 DSL mode) Considerations
Because the HD-10 is a double-wide module, it occupies the physical space of two
slots. There is no protection feature available for this technology.
NOTE
1. When wiring for HDSL, pairs 1 and 2 wire out to Loop 2 and Loop 1,
respectively.
2. When wiring for HDSL2, its signal is delivered to the loop on pair 2.
3. When wiring for ISDN, see Table 6 and Table 7 for more details.
