The NMI and DMM connectors on the standard transition board are not included on the
DBB. Connection to the CMS 400 network management system is made through the
Excalibur Card Carrier's Cage Input/Output (I/O) Card. The CMS control signals are
routed to the DBBs through a bus on the chassis backplane.
User Indicator
Each DBB has a LED indicator, labeled USER, that lights continuously while its
associated DAD is participating in a dial restoral activity. It flashes while the DAD is
selected by the control panel.
AC Power Connection
The Excalibur Multirate DAP draws power from a 92-127 VAC external power supply
that plugs directly into your AC power outlet. To make this connection, plug one end of
the power supply cable into the DAP's POWER receptacle and plug the other end into
the AC outlet. Figure 3-11 illustrates this connection.
Note: If there is a snap-on ferrite in the package containing this manual and the cables,
it must be attached to the DC power cable as close to the DAP as possible. See Figure 3-
11. The ferrite must be installed to comply with FCC Part 15 Requirements. If the ferrite
is not included in the package, it is not needed.
Caution: For use with Power Supply Part No. 25C168-01.
