Daughterboard configurations
The DBs are available in two sizes: An NTDW62 32-port daughterboard
(DB-32) and an NTDW64 96-port daughterboard (DB-96).
There are four possible Media Gateway configurations:
• A pure TDM single Media Gateway with no DSP daughterboards or
Media Cards.
• A system with only Media Card.
• A system with only DSP daughterboards.
• A system with both DSP daughterboards and Media Cards.
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.
