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 the 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 1:1 protection feature available for this technology.
1.1.4
DSX-1 Considerations
The DSX-1 access module is used to drop a single DSX-1 channel out of an STS-1 or
DS-3 data stream for use locally in the CO or for further transport. Consequently, the
DSX-1 access module is used only for MUX-fed applications, and sends its 4-wire
DSX-1 signal out to pairs 7 and 8, where DSX-1 signals are normally found on the
Total Access3000/3010. There is no 1:1 protection capability in the DSX-1 access
module.
