HDSL Interface
The HDSL interface block connects the HDSL loops to the MX and DX blocks. The block can
provide loop switching, as well as loopback for each external incoming loop and a loopback for the
internal MX signals to the DX block.
Figure 6
shows the possible signal routings. When the
HDSLLB bit in the LPCTL register (
Table 5
) is set, all HDSL Interface loopbacks are set. The
LOOP_REV block shows how any loop swap combination can be set by the DX Process in
Figure
2.3
. The status of the loop connections can be monitored by reading the LPREV bits in the
LPRSTAT register. See
Table 28
.
