NTDW62, NTDW64, and NTDW78 DSP daughterboards

The NTDW60 Media Gateway Controller provides Digital Signal Processor
(DSP) resources with the NTDW62 32-port DSP daughterboard, the
NTDW64 96-port DSP daughterboard, and the NTDW78 128-port DSP
daughterboard. These daughterboards transcode between IP and TDM
devices in a CS 1000E. The daughterboards eliminate the need for Voice
Gateway Media Cards in an MG 1000E, although the system can contain
both DSP daughterboards and Voice Gateway Media Cards, if desired.
Two positions are available on the MGC card for DSP daughterboards.
The following configurations of daughterboard placement on a Media
Gateway Controller are possible:
•
an NTDW62 32-port in position 1
•
an NTDW62 32-port in position 2
•
an NTDW62 32-port in position 1 and an NTDW62 32-port in position 2
•
an NTDW64 96-port in position 1
•
an NTDW64 96-port in position 1 and an NTDW62 32-port in position 2
