The DB-96 is supported only in expansion site #1 on the MGC card. If
a DB-96 is detected in expansion site #2 during bootup, an installation
error message is displayed on the MGC faceplate. The installation
error message remains on the MGC faceplate display until the DB-96 is
removed from expansion site #2. The DB-96 installation error message
can be cycled through with other error messages. The DB-32 is supported
in both expansion sites on the MGC card.
There are five possible DSP daughterboard configurations for both Call
Server or Media Gateway configurations (3) and (4):
•
A DB-32 in DB expansion site #1.

#2.
•
A DB-96 in DB expansion site #1.
