Remote Power Supply
The1642 AM and 1643 AMS units, as SHDSL LTUs, are connected to third-party
NTUs and SHDSL Regenerator Units (SRUs). To enable the remote powering of an
SRU, an external power box called the Fernspeisemodul (FSP) box or the External
SHDSL Power Supply (ESPS) box is delivered alongwith the unit.
This external power supply box is managed through the MDI/MDO interfaces located
on the NE. The power box is monitored by manually setting the DIP switch on the box
to “Managed” and setting the NE to the managed mode. There are also individual DIP
switches to monitor each port on the box. The management system displays the status,
“FSP on/off”, of the DIP switches per port.
The MDI/MDO interfaces on the power box can be used by the1642 AM and 1643
AMS units as the MDI/MDO interfaces for external signalling.
