Each of the three Quad ADSL Access Modules
communicates via the backplane with the ATM BCU
and accepts four POTS signals from the CO. Each
ADSL module provides four 2-wire ADSL plus POTS
interfaces toward a customer. A fully loaded system
uses three Quad ADSL Access Modules and provides
12 data plus voice services. See
Figure 3
for an
application diagram.
Span Power
The Total Access 1000 DAT is completely powered
from the HDSL2 spans and requires at least three
spans of HDSL2 for proper operation.
WARNING
Risk of electric shock. Voltages up to 190 VDC
may be present on telecommunications circuit.
Always ensure that the frame ground is connected
to the lug inside the OSP housing.
